Yesterday I received an Amazon Dash for ordering IZZE juice.
I think it is a great device, not that I would order tons of IZZE from Amazon, but at $5 it has wifi module + a micro controller + a LED light + a battery + nice enclosure, and it’s usually in deep sleep which means the device can last for years. That’s a bargain – a similar device would cost $20 – $40, at least before ESP8266 became available.
First thing I tried is to re-purpose it to toggle on/off the poor man’s Nest screen, because the PiTFT screen is quite bright and gets warm, I want to turn it off without unplugging the cord, and turn it back on instantly if needed. And here is it. Note the IZZE sticker color coordinates well with Nest warm yellow color
The signal cycle goes through PubNub, which has MQTT at its core, the response time is less than 0.5 second. So it is remotely controlled – if leave poor man’s Nest in office, I can push the button at home to turn it off.
While my daughter is excited about the IZZE toggle button controlling PiTFT screen, my wife asked me to do something more meaningful So I made a second try, turned IZZE button to be a “dinner time” call button.
Every time when dinner is ready, I have to shout toward upstairs to get my kids, and more often than not, I couldn’t get them because they have head-phones on.
So I modified a little bit of the code, to listen for IZZE wake up and try to connect to my router, then use that signal to ask Philips Hue lights to blink 3 times.
Now my wife can just press IZZE button in the kitchen, the Hue lights at my kid’s desk start to blink, and that’s dinner time call.
I guess that is more meaningful, at least I don’t have to shout toward upstairs again Possibly Related Posts:

We are always on the hunt for interesting new uses of the Apple Watch, so when my colleague Ben Bendig alerted me to AstroPad’s new iPhone/Apple Watch app, I downloaded it immediately.
The app, AstroPad Mini, is intended to let you use your iPhone as a graphics tablet and controls Photoshop nicely right out of the box. But it will work with any Mac app; it lets you map any area of your Mac screen to the iPhone and map up to eight keyboard commands to buttons in an Apple Watch app. I reprogrammed it to work with NodeBox.
Although you can zoom and pan the Mac screen from your iPhone, this seems awkward for precision work (the iPad app would work better for that). It was more useful to map a small control area of the screen to the iPhone instead. For Photoshop you could arrange palettes (tools, layers, history) and dialogs (e.g. color picker) into a corner somewhere (maybe on a second monitor), map the iPhone to that, and use the iPhone as an auxiliary screen so you don’t have to keep moving your mouse back and forth. This worked particularly well for the color picker.
For NodeBox I mapped the node pane, a small area which displays properties of the currently selected node. I could then select any node on my ginormous screen using a mouse or trackpad and then scrub its properties from the phone (without having to relocate the mouse).
Even more fun: I mapped common actions to Apple Watch buttons: Save, Full Screen, Escape, New Node, Undo, Redo, Play, and Rewind. When creating animations, it’s pleasant to lean back in my chair, put the display in full screen, and play and rewind to my hearts content all from my watch.
I was also able to focus the iPhone on the slider of my transforming table (running as a web app) and could then stand back from the display and move the slider back and forth from my phone. You could do the same thing by just running the table app on the phone and mirroring it via AirPlay, but AstroPad let me focus the entire iPhone screen on the slider so that it was easier to manipulate.
The app did occasionally lose its wifi connection for a few moments, but otherwise worked fine.
I think with a little thought and practice this setup could speed my workflow somewhat. The benefits are marginal, though, not revolutionary. One tip: if you use the Apple Watch be sure to set “Activate on Wrist Raise” to “Resume Previous Activity” instead of “Show Watch Face” so that you don’t have to keep relaunching the AstoPad app.
We could conceivably use this app in some of the concept demos our group does. It would be a quick and dirty way of controlling some features from an iPhone or Apple Watch without having to write any special code. The catch is that the demo would have to run on a Mac. One advantage: they have an option for controlling the Mac via USB cable instead of wifi, a handy workaround at HQ or demo grounds when sharing a local wifi router is problematic.
Hmmm. I wonder if I could aim and fire my USB Rocket Launcher from my watch. Now THAT might be a killer app.Possibly Related Posts:

The Intel Compute Stick provides a full desktop experience in an ultra-portable HDMI dongle form factor. It’s like Google Chromecast, but an entire PC instead of just a web browser. I tested both the $150 Windows 8 version and the new $110 Ubuntu version.
TAP TAP TAP. IS THIS THING ON?
The HDMI end goes into a display, the power goes into an outlet, and a blue light comes on but the Stick does not boot. Either tap or long press the power button, then switch the display input source after a few seconds. Just by looking at the Stick you cannot tell if it’s off, on, or booting. Long press the power button and you may end up at the boot menu or the blue light may go off—I suppose making the Stick even more off than previously.
It boots. This is where you need to find a keyboard, then a little later find a mouse. See, there’s only one USB port on the Stick so we ended up swapping peripherals during the setup. This gets old instantly so either get a USB hub or some bluetooth peripherals. Unsurprisingly, the Microsoft bluetooth keyboard we got from our local StaplesMax Depot did not like the Ubuntu version of the Stick so we needed a hub.
You will want to plug the included HDMI extension cable into the Stick or your wifi will be—at least in my experience—absent. Use the micro-USB charger that came with the Stick if you want it to boot at all. It’s a proprietary charger masquerading as non-proprietary. It’s better to find this out now rather than on the road. All of these non-moving parts make for something…squiddy.
GETTING THAT FOR WHICH YOU PAID
I type this now with the intestines. The quick brown fox jumps over the lazy dog. It performs well for the tasks that most people perform most often, but then again we live at a time where my $35 MP3 player has a word processor, plays chess, and even runs the game DOOM.
Web pages load with a small delay but I have little complaint there. YouTube, for example, runs smoothly and overall the Stick is fine for common tasks.
Lag is lag. While typing I get periodic freezes. No words appear and then all of a sudden abracadabra. Opening a folder in the file manager sometimes takes a few beats. There’s a 64-bit quad-core Atom processor inside® but it sometimes feels like Mac OS 8 or Windows 3.1 on 20 year old hardware. Fun fact: the Ubuntu Stick has 1GB RAM / 8GB storage while the Windows Stick has 2GB RAM / 32GB storage. The internet says you can install Linux on the Windows version.
Let’s push things a bit. The Leap Motion is a cool USB device which tracks your hands’ motions and provides an API to do things with that data. Even though the Stick doe—oops, freeze-up—does not meet the minimum requirements, why not give it a try? I’m sure it’s fine and no harm will come of it.
PART NUMBER II
The Leap Motion did not work so I tried rebooting the Stick. And tried. And tried. And tried… Sure, I had not mastered the power button but this was different. The Stick would show the Ubuntu splash screen and then go endlessly dark. Luckily, others had faced the same issue. I simply had to hold the power button for just less than 4 seconds—not 4 seconds, mind you—to get into the boot menu, then choose to recover the BIOS. BIOS recovery did not fix the black screen. Update the BIOS then. That went smoothly, but did not fix it. There were other trials too.
At this point, I just wanted the beginnings of this very blog post off of the Stick. I decided to make a bootable USB drive so I could at least grab the document. I’ve only made “live” CDs/DVDs before and making a live USB stick was more challenging and time-consuming than I had anticipated. I was able to get GParted installed but then decided Puppy Linux with persistency would be easier. I tried doing this on my Linux machine at home but in the end the easiest thing I found was LinuxLive USB Creator on Windows. Prepared, I hoped that the next day I would be able to grab those words up there from the borked Stick.
When I got to work I decided to try the Stick again: same problem, of course. I had a meeting so I left it plugged in. When I got back I tried rebooting, ever the naïve optimist.
It boots!!! And an error message popped up, perhaps the cause of all of this: The volume “Filesystem root” has only 156.5 MB disk space remaining. Where had I seen that before?
My confidence restored along with the bootability, I am continuing this blog post on the Stick. It is behaving well with little lag although Firefox crashed a couple times with one tab open. I’m not entirely sure if this is “normal” or if the trials and tribulations took their toll.
If the self-healing mini-miracle had not happened, would I have been able to boot from the USB stick? No. There’s a Catch-22 because of the sole USB port. The keyboard needs that port to use the boot menu. Using the hub or switching to the hub when at that menu ends all input from then on. There is a micro SD slot, and if I wasn’t exhausted from all of this I would try to boot from it.

If not, here’s a recap of some of the tinkering going on in OAUX Emerging Technologies land.
Meanwhile, Raymond (@yuhuaxie) has been busy building a smart thermostat.
And finally, completely unrelated to IoT tinkering, earlier this month the Oracle Mexico Development Center (MDC) in Guadalajara celebrated its fifth anniversary. As you know, we have two dudes in that office, Os (@vaini11a) and Luis (@lsgaleana), as well as an extended OAUX family. Congratulations.

If you read here, you’ll recall that Noel (@noelportugal) and I have been supporters of the Raspberry Pi for a long time, Noel on the build side, many, many times, me on the talking-about-how-cool-and-useful-it-is side.
And we’ve been spreading the love through internal hackdays and lots of projects.
So, yeah, we love us some Raspi.
The little guy has become our go-to choice to power all our Internet of Things (IoT) projects.
Given all that we do with Raspis, I’ve always meant to get one for my own tinkering. However, Noel scared me off long ago with stories about how long it took to get one functional and the risks.
For example, I remember reading a long post early on the Pi’s history about how choosing a Micro USB was critical, amperage too high burned out the board, too low and it wouldn’t run.
The information was out there, contributed by a huge and generous community. I just never had the time to invest.
Recently, I’ve been talking the good people at the Oracle Education Foundation (@ORCLcitizenship) about ways our team can continue to help them with their workshops, and one of their focus areas is the Raspberry Pi.
After all, the mission of the Raspi creators was to teach kids about computers, so yeah.
I figured it was finally time to overcome my fears and get dirty, and thanks to Noel, I found a kit that included everything I would need, this Starter Kit from Vilros.
Armed with this kit, I took a day and hoped that would be enough to get the little guy running. About an hour after starting, I was done.
Going from zero to functional is now ridiculously easy, thanks to these kits that include all the necessities.
So, now I have a functioning Pi running Raspbian. All I need is a project, any ideas?
Coda: Happy coincidence, as I wrote this post, I got a DM from Kellyn Pot’Vin-Gorman (@dbakevlar) asking if knew any ways for her to use her Raspberry Pi skills in an educational capacity. Yay kismet.

A couple months a go IFTTT added a much needed feature: A custom channel for generic urls. They called it the Maker Channel. If you noticed my previous post, I used it to power an IoT Staples Easy Button.
At a closer look this is a very powerful feature. Now you can basically make and receive web requests (webhooks) from any possible connected device to any accessible web service (API, public server, etc..) It is important to highlight that requests “may” be rate limited, so don’t start going crazy with Big Data style pushing.
You can also trigger any of the existing Channels with the Maker Channel. So either you can choose to trigger any of the existing Channels when you POST/GET to the Maker Channel:
Or you could have IFTTT POST/GET/PUT to your server when any of the existing Channels are triggered.
Do you use IFTTT? Do you find it useful? Let me know in the comments.Possibly Related Posts:

The Amazon Dash button, it’s all the buzz lately. Regardless whether you think it is the greatest invention or just a passing fad, it is a nice little IoT device. There is already work underway to try and make it work with custom code.
This is where the up and coming ESP8266 mcu can shine. For under $3 you can have a wifi chip plus a programable micro-controller. You just need to add a cheap button (like the Staples Easy Button for around $7.) Add good ol’ IFTTT Maker Channel and you will be set to go with your custom IoT button for about $10.
Check my hackster.io project (https://www.hackster.io/noelportugal/esp8266-ifttt-easy-button) to learn how to make your own.

Recently, my four year-old daughter and her little bestie were fiddling with someone’s iPhone. I’m not sure which parent had sacrificed the device for our collective sanity.
Anyway, they were talking to Siri. Her bestie was putting Siri through its paces, and my daughter asked for a joke, because that’s her main question for Alexa, a.k.a. the Amazon Echo.
Siri failed at that, and my daughter remarked something like “Our Siri knows the weather too.”
Thus began an interesting comparison of what Siri and “our Siri” i.e. the Echo can do, a pretty typical four year-old topping contest. You know, mine’s better, no mine is, and so forth.
After resolving that argument, I thought about how natural it was for them to talk to devices, something that I’ve never really liked to do, although I do find talking to Alexa more natural than talking to Google Now or Siri.
I’m reminded of a post, which I cannot find, Paul (@ppedrazzi) wrote many years ago about how easily a young child, possibly one of his daughters, picked up and used an iPhone. This was in 2008 or 2009, early days for the iPhone, and the child was probably two, maybe three, years old. Wish I could find that post.
From what I recall, Paul mused on how natural touch was as an input mechanism for humans, as displayed by how a child could easily pick up and use an iPhone. I’ve seen the same with my daughter, who has been using iOS on one device or another since she was much younger.
I’m observing that speech as equally natural to her.
Kids provide great anecdotal research for me because they’re not biased by what they already know about technology.
When I use something like gesture or voice control, I can’t help but compare it to what I know already, i.e. keyboard, mouse, which colors my impressions.
Watching kids use touch and voice input, the interactions seem very natural.
This is obvious stuff that’s been known forever, but it took how long for someone, Apple, to get touch right? Voice is in an earlier phase, advancing, but not completely natural.
One point Noel (@noelportugal) makes about about voice input is that having a wake word is awkward, i.e. “Alexa” or “OK Google,” but given privacy concerns, this is the best solution for the moment. Noel wants to customize that wake word, but that’s only incrementally better.
When commanding the Amazon Echo, it’s not very natural to say “Alexa” and pause to ensure she’s listening. My daughter tends to blurt out a full sentence without the pause, “Alexa tell us a joke” which sometimes works.
That pause creates awkward usability, at least I think it does.
Since its release, Noel has led the charge for Amazon Echo research, testing and hacking (lots of hacking) on our team, and we’ve got some pretty cool projects brewing to test our theories. I’ve been using it around my home for a while, and I’m liking it a lot, especially the regular updates Amazon pushes to enhance it, e.g. IFTTT integration, smart home control, Google Calendar integration, reordering items from Amazon and a lot more.
Amazon is expanding its voice investment too, providing Alexa as a service, VaaS or AVS as they call it.
I fully believe the not-so-distant future will feature touch and speech, and maybe gestures, at the glance and scan layers of interaction, with the old school keyboard and mouse for heavy duty commit interactions.
So, what do you think? Thank you Captain Obvious, or pump the brakes Jake?

For me, 2015 has been the year of the quantified self.
I’ve been tracking my activity using various wearables: Nike+ Fuelband, Basis Peak, Jawbone UP24, Fitbit Surge, and currently, Garmin Vivosmart. I just set up Automatic to track my driving; check out Ben’s review for details. I couldn’t attend QS15, but luckily, Thao (@thaobnguyen) and Ben went and provided a complete download.
And, naturally, I’m fascinated by biohacking because, at its core, it’s the same idea, i.e. how to improve/modify the body to do more, better, faster.
Ever since I read about RFID chip implanting in the early 00s, I’ve been curiously observing from the fringe. This post on the Verge today included a short video about biohacking that was well worth 13 and half minutes.
If you like that, check out the long-form piece, Cyborg America: inside the strange new world of basement body hackers.
This stuff is fascinating to me. People like Kevin Warwick and Steve Mann have modified themselves for the better, but I’m guessing the future of biohacking lies in healthcare and military applications, places where there’s big money to be made.
My job is to look ahead, and I love doing that. At some point during this year, Tony asked me what the future held; what were my thoughts on the next big things in technology.
I think the human body is the next frontier for technology. It’s an electrical source that could solve the modern battery woes we all have; it’s an enormous source for data collection, and you can’t forget it in a cab or on a plane. At some point, because we’ll be so dependent on it, technology will become parasitic.
And I for one, welcome the cyborg overlords.

Noel (@noelportugal) talked about the technical bits in a post last week, and today, ODTUG posted an interview featuring our fearless leader, Jeremy Ashley (@jrwashley), and Noel from the conference wherein they talk about Internet of Things (IoT) and the IoT bits included in the Hunt.
If you read here, you’ll know that IoT has been a long-time passion of Noel’s, dating back to well before Internet-connected devices were commonplace and way before they had an acronym.
Thanks to ODUTG for giving us the opportunity to do something cool and fun using our nerdy passion, IoT.Possibly Related Posts:

The Apple Watch came out, and we had a lot of questions: What do people want to do on it? What do they expect to be able to do on it? What are they worried about? And more importantly, what are they excited about?
But we had a problem—we wanted to ask a lot of people about the Apple Watch, but nobody had it, so how could we do any research?
Our solution was to do some guerrilla testing at the OHUG conference in June, which took place in Las Vegas. We had a few Apple Watches at that time, so we figured we could let people play around with the watch, and then ask them some targeted questions. This was the first time running a study like this, so we weren’t sure how hard it would be to get people to participate by just asking them while they were at the conference.
It turned out the answer was “not very.” We should have known—people both excited and skeptical were curious about what the watch was really like.
Eventually we had to tell the people at our recruiting desk to stop asking people if they want to participate! Some sessions went on for over 45 minutes, with conference attendees chatting about different possibilities and concerns, brainstorming use cases that would work for them or their customers.
The activity was a great success, generating some valuable insights not only about how people would like to use a smartwatch (Apple or not), but how they want notifications to work in general. Which, of course, is an important part of how people get their work done using Oracle applications.
Our method was pretty simple: We had them answer some quick survey questions, then we put the watch on them and let them explore and ask questions. While they were exploring, we sent them some mock notifications to see what they thought, and then finished up asking them more in depth about what they want to be able to accomplish with the watch.
At the end, they checked off items from a list of notifications that they’d like to receive on the watch. We recorded everything so we didn’t have to have someone taking notes during the interviews. It took some time to transcribe everything, but it was extremely valuable to have actual quotes bringing to life the users’ needs and concerns with notifications and how they want things to work on a smartwatch.
Most usability activities we run at conferences involve 5–10 people, whether it’s a usability test or a focus group, and usually they all have similar roles. It was valuable here to get a cross-section of people from different roles and levels of experience, talking about their needs for not only a new technology, but also some core functionality of their systems.
In retrospect, we were a little lucky. It would probably be a lot more difficult to talk to the same number of people for an appreciable amount of time just about notifications, and though we did learn a good deal about wants and needs for developing for the watch, it was also a lot broader than that.
So one takeaway is to find a way to take advantage of something people will be excited to try out—not just in learning about that specific new technology, but other areas that technology can impact.Possibly Related Posts:

As we found out, scavenger hunts are a great way to get people to see your content, create buzz and have fun along the way. We also used the scavenger hunt as a platform to try some of the latest technologies. The purpose was to have conference attendees complete tasks using Internet of Things (IoT), Twitter hashtags and pictures and compete for a prize.
Here is a short technical overview of the technologies we used.
We opted to use a Node.js back-end and a React front-end to do a clever Twitter name autocomplete. As you typed your Twitter handle, the first and last name fields were completed for you. Once you filled all your information the form submitted to a REST endpoint based on Oracle APEX. This piece was built by Mark Vilrokx (@mvilrokx) and we were all very happy with the results.
We researched two possible technologies: Bluetooth Low Energy (BLE) Beacons and Near Field Communication (NFC) stickers and settled for NFC. The reason behind choosing NFC was the natural tendency we have to touch something (NFC scanner) and get something in return (notifications + points). When we tested with BLE beacons the “check-in” experience was more transparent but not as obvious when trying to complete a task.
We added a NFC sticker to all scavenger hunt participants’ badges so they could get points by scanning their badge in our Smart Scanners. To provision each NFC badge we build an Android app that took the tag id and associated with the user profile.
The Smart Scanner was a great way to showcase IoT. We used the beloved Raspberry Pis to host an NFC reader. We used the awesome blink(1) USB LED light to indicate whether the scan was successful or not. We also added a Mini USB Wi-Fi dongle and a high capacity battery to assure complete freedom from wires.
Raymond Xie (@YuhuaXie) did a great job using Java 8 to read the NFC stickers and send the information to our REST server. The key part for these scanners was creating a failover system in case of internet disconnection. In such case we would still read the NFC tag and register it, then it would post it to our server as soon as connectivity was restored.
Twitter and SMS Bots
Another key component was to create a twitter and SMS bot. Once again, Mark used Node.js to consume the Twitter stream. We looked for tweets mentioning #kscope15 and #taskhashtag. Then we posted to our REST server which made sure that points were given to the right person for the right task. Again we were pleasantly surprised by the flexibility and power of Node.js. Similarly we deployed a Twilio SMS server that listened for SMS subscriptions and sent SMS notifications.
We just didn’t settled by creating a web client to keep track of points. We created a web mobile client (React), an iOS app and an Android app. This was part of our research to see how people used each platform. As a bonus we created Apple Watch and Android Wear companion apps. One of the challenges we had was to create a similar experience across platforms.
We needed a way to manage all task and player administration. Since we used APEX and PLSQL to create our REST interface, it was a no brainer to use APEX for our admin front-end. The added bonus was that APEX has user authentication and sessions management, so all we had to do is create admin users with different roles.
Creating a scavenger hunt for tech conference is no easy task. You have to take into consideration many factors, from what are the right task for the conference attendees to having the optimal wifi connection. Having an easy registration and provisioning process are also paramount for easy uptake.
We really had fun using the latest technologies and we feel we successfully showcased what good UX can do for you across different devices and platforms. Stay tuned to see if we end up doing another similar activity. You wont want to miss it!Possibly Related Posts:

Last week a group of high school students from Royal High School visited Oracle Headquarters in Redwood Shores, California.
Royal High School, a public school in Simi Valley, California, is launching an International Business Pathway program. This program is part of California’s Career Pathways Trust (CCPT), which was established in 2013 by the California State Legislature to better prepare students for the 21st Century workplace.
The goal of the visit was to introduce students to real life examples of what they will be studying in the year ahead, which include Business Organization and Environment, Marketing, Human Resources, Operations, and Finance.
I was honored to be invited to be on a career panel with three other Oracle colleagues and share our different careers and career paths.
While Oracle is known as a technology company, it is comprised of many different functional areas beyond engineering. The panel shared our diverse backgrounds and education, our different roles within the organization, the different cultures within Oracle, and more.
Since these are students in an international business program, we also discussed Oracle as a global business. The panelists shared our individual involvement and impact on Oracle’s international business – from working with Oracle colleagues located throughout the world to engaging with global customers, partners, and journalists.
By the end, the students heard stories of our professional and personal journeys to where we are now. The common themes were to be authentic and true to yourself, change is inevitable, and it is a lifetime of learning. All of the panelists started on one path but ultimately found new interests and directions.
The students learned there are many different opportunities in companies and many different paths to achieve career and life goals. Bring your passion to work and you’ll succeed.
On a personal note, I grew up in the same area as these students, that being the San Fernando Valley in Southern California. I moved from the San Fernando Valley to the Silicon Valley years ago, but thanks to Oracle Giving, I am able to give back to my roots and proud to participant in Oracle’s community outreach .Possibly Related Posts:

User experience design as a career fell largely on the era of GUI. Thus most people in my profession are visual thinkers if not by birth than by experience. When it comes to presenting information, we think visualization. Times are changing, and with that we are challenged to present information verbally. This is where text analytics meets UX. I only worked on a handful of projects that are about text, and only with a handful of text technologies, but the experience has been worth mentioning.
Text analytics, more or less meaning the same as text mining, is “devising of patterns and trends from text through means such as statistics…” (Oh, Wikipedia!)
There are many areas of text analytics – text summarization, information retrieval, sentiment analysis, named entity recognition, and on… The tools and techniques are constantly getting better, it is exciting. I get an impression that the text mining companies are intoxicated with the coolness of technologies they build, so they think of it first and think of possible industry applications later. As I am conditioned to think in an opposite direction, it was interesting for me to see how the same technique can be so useful in one case and completely irrelevant in another.
Here is my use case inventory. Take a brand manager versus a sales representative. A brand manager might like daily sentiment analysis of her brands and those of her competitor. On the other hand, the sales representatives we have interviewed are not at all into sentiment analysis. What they look for is highly tuned searches that would brief them daily on what’s happening with their top clients. They also search for industry news that they can retweet with a hope to influence the clients. A money manager might need to use text analytics to contextualize the jump in a stock price, while a marketer would rather have a predictive text mining tool to target customers for a purchasing recommendation. I often research different design topics and am interested in text analytics that would make me see at a glance what a collection of papers or articles is about. I also like to see daily summaries of trending topics in design and technology.
So the first lesson I’ve learned is how all text analytics use cases are different.
The second lesson is how the devil is in detail.
For one of my project, I wanted to have a condensed representation of press coverage for the new release of HCM applications, specifically, its user experience. For my purposes, I wanted to have it as a cloud of words. I have collected a number of press releases and reviews, and fed them through four text analytics tools I could put my hands on, namely Semantria, Open Calais, TagCrowd, and Oracle’s own Social Relationship Management (SRM) Listen and Analyze.
Here are the results.
For the fairness of the comparison, I have stripped the lists of its the original formatting (the products have drastically different interfaces), and limited the results to 20 items. Moreover, some packages categorize the results into “themes,” “entities,” etc. I kind of had to either pick or merge. SRM doesn’t allow me to feed corpus of text to it to analyze, so I had to create a search query about OAUX instead.
You can see that the differences are dramatic. I believe some differences are the results of subtle choices made by the product designers – frequency thresholds, parts of speech included, the choice of either 1, 2 or 3 word phrases, etc. Other differences are the results of the actual algorithms beneath – bag of words, word vectors, neural nets, skip grams, chaining, deep learning, … . At first, I was determined to figure them all out. I quickly realized that there is no way I can get through the math of it. So I decided to approach it in a chocolate tasting way. If I like the taste, I’ll make an effort to read the ingredients.
Semantria I liked the most. I liked the combination of themes and entities; I thought the length of the phrases was well balanced. I read the ingredients. Instead of plain word frequencies, Semantria uses something called “lexical chaining” to score themes. “The algorithm takes context and noun-phrase placement into account when scoring themes.” I put “lexical chaining” high on my list of likes.
OpenCalais looked totally solid, though heavy on terms and nouns, and light on themes and adjectives. This is to no surprise, as Named Entity Recognition is OpenCalais’ core competency, and there it is unsurpassed. The new “generic relations” feature in a shape of a “subject-predicate-object” is amazing.
TagCrowd’s was definitely too plain to represent what the collection is about. This is a very simple well-meaning word frequency tool, with the stop words (the and a removed) being its only “lexical analysis” feature. From TagCrowd I’ve learned that the word frequencies can take you only that far.
Finally, there is SRM. SRM uses latent semantic analysis, which is a type of vectorial technique.

In my previous post I argued that the hunt is on for a better way to code, a way more suited for a designer’s need to test new interactions. I said I wanted a process less like solving a Rubik’s cube and more like throwing a pot. What does this actually mean?
“I want to grab a clump of clay and just continuously shape it with my hands until I am satisfied.”
There are two key concepts here: “continuously shape” and “with my hands.”
Code that is continuously shaped is called reactive programming. A familiar example is the spreadsheet: change a single cell and the rest of the sheet automatically updates. There is no need to write a series of instructions and then “run” them to see what happens; instead every change you make instantly affects the outcome.
“With my hands” refers to a kinesthetic or visuospatial style of thinking which leverages our ability to perceive and manipulate spatial relationships. Traditional programming languages are frustrating for visual thinkers; they rely on a phonological style which uses hands only to type and eyes only to read.
In theory, any written language can instead be represented as a collection of elements arranged and connected in space; this is the idea behind visual programming languages. Instead of typing instructions, you drag objects around and connect them together to express ideas.
The image above includes some typical examples. Block style IDEs (e.g. Scratch) let you snap together commands like Lego bricks. The others let you drag boxes around and string wires between them.
I think it’s easy to see at a glance the problem with this approach: it doesn’t scale. Stringing wires or snapping bricks gets really messy really fast. Reaching elbow deep into a rat’s nest of wires is not anything like shaping clay.
But it doesn’t have to be this bad. The problem these examples have is that, although visual, they slavishly adhere to an imperative style of coding where instructions are listed in order and even the words within each instruction must follow a specific syntax. This forces connections into arbitrary knots and loops, creating more tangles and going against the overall flow. A visual style demands a simpler, more fluid kind of logic.
Enter an old idea in computer science which has seen a recent resurgence: functional programming. In place of a sequence of instructions which focus on how to do things, functional programming languages use chains of transformations that focus on the desired result at each point. Loops are banished and each node can have only one output so everything naturally flows in the same direction. A classic example is Lisp; a more modern functional language now gaining traction is Clojure. Don’t be scared.
So what we need is a functional reactive programming language with a responsive, fun to use visual IDE, designed specifically for artists. Extra bonus points if it includes natural scrubbing interactions for setting values ala Bret Victor.
Meet NodeBox. NodeBox is an open source, cross-platform GUI originally developed for generative artists. I first encountered it at the OpenVis conference in 2013. The video of that presentation is a great introduction; you can skip to 22:00 to see a demo of NodeBox in action which shows how quickly and easily you can shape a visualization. This is what I mean by shaping clay.
This NodeBox “network” draws a set of nested pentagons. The structure is so simple you can see how it works just by looking at it. Make a pentagon node, color it, hook it to a “nextChild” subnetwork that makes a smaller copy, repeat three more times, then combine all five pentagons into a single display.
You can double-click on any node to render it on the main screen; a white triangle in the lower right corner indicates the currently rendered node. You can then single-click any other node to adjust its parameters – in this case the original pentagon node. By scrubbing (dragging the mouse across) the radius field I can increase or decrease its size; making the top pentagon bigger will automatically make all its children bigger. In this way I can quickly scrub values to get the result I want.
Another (somewhat mind-bending) example: a NodeBox network which can draw itself. On the right is a set of nodes that opens a JSON file, analyzes the contents, and plots it as a series of rectangles and connecting lines. On the left is what happens when that JSON file happens to contain this network’s own structure (taken directly from it’s .ndbx file).
I’ve been playing with NodeBox for about six months now and have created over forty networks which let me play with and try out various visualizations and data-driven animations. I find that some things which are easy to do in other languages are hard to do in NodeBox (or just hard for me to figure out how to do). But the reverse is also true: some things that are difficult or time-consuming to do in any other language are spectacularly easy in NodeBox.
Debugging, in particular, is much less time-consuming and almost fun. I catch most bugs instantly since every change I make is instantly rendered. When something unexpected does happen I can just click on each node in turn to follow the steps of a process. When something is too big or too small or in the wrong place I can simply scrub a parameter or even just grab the offending object and drag it where it needs to go.
Scaling up to large projects is manageable, but remains problematic. If you think clearly enough you can encapsulate everything into a handful of subnetworks and sub-subnetworks. But this can only go so far. NodeBox’s functional approach eliminates “side effects;” a change made to one function cannot affect distant functions unless those two functions are physically linked. This prevents the nasty hard-to-trace bugs which plague procedural languages, but it also means there are no global variables, which in turn means that if you want a variable to effect twenty different functions you will need to create at least twenty separate links.
You can alleviate this somewhat by using Null nodes as cable ties. If two clumps of nodes have many interlinkages, you can physically separate them, lay one cable across the void to a Null node, and then distribute its output from there. After I get something working in NodeBox I usually spend some more time “tidying up,” rearranging nodes into related clumps and positioning nodes to reduce the number of crossing lines. I regard this not as a nuisance, but as a pleasant, almost meditative ritual that helps me optimize my code.
NodeBox does have one major limitation: it doesn’t do input. It was designed to produce intricate still images and animations, not to facilitate end user interactions. So there are no input fields, no buttons, no sliders, no checkboxes – no way to create a standalone interactive prototype. These things could all be done in theory, it’s just that NodeBox does not currently provide any *nodes* to do them.
This is ironic because the NodeBox IDE itself is richly interactive. It’s vector-based ZUI (zoomable user interface) is a joy to use. So as a designer I can experience wonderful interactions by scrubbing node parameters and zooming in and out, but I can’t create a similar experience for my end users.
My use of NodeBox, therefore, is limited to creating sketches and animations. This is no small thing – it allows me to play and try and then convey the essence of ideas which are inherently hard to test and demonstrate. But for now I will still have to move to other languages if I need to create stand-alone interactives.
I think the deeper value of NodeBox is that it shows what is possible. There are better ways of imagining, better ways of coding. If we hope to create ever better experiences for our users, we need to keep searching for these better ways.Possibly Related Posts:

- Fact 1: Dazzling animated displays (sprites, shaders, parallax, 3D) are more plentiful and easier to make than ever before.
- Fact 2: More natural and expressive forms of input (swiping, pinching, gesturing, talking) are being implemented and enhanced every day.
- Fact 3: Put these two together and the possible new forms of human computer interaction are endless. The only limit is our imagination.
That’s the problem: our imagination. We can’t build new interactions until A) someone imagines them, and B) the idea is conveyed to other people. As a designer in the Emerging Interactions subgroup of the AppsLab, this is my job – and I’m finding that both parts of it are getting harder to do.
If designers can’t find better ways of imagining – and by imagining I mean the whole design process from blank slate to prototype – progress will slow and our customers will be unable to unleash their full potential.
So what does it mean to imagine and how can we do it better?
Imagination starts with a daydream or an idle thought. “Those animations of colliding galaxies are cool. I wonder if we could show a corporate acquisition as colliding org charts. What would that look like?”
What separates a mere daydreamer from an actual designer is the next step: playing. To really imagine a new thing in any meaningful way you have to roll up your sleeves and actually start playing with it in detail. At first you can do this entirely in your mind – what Einstein called a “thought experiment.” This can take weeks of staring into space while your loved ones look on with increasing concern.
Playing is best done in your mind because your mind is so fluid. You can suspend the laws of physics whenever they get in the way. You can turn structures inside out in the blink of an eye, changing the rules of the game as you go. This fluidity, this fuzziness, is the mind’s greatest strength, but also its greatest weakness.
So sooner or later you have to move from playing to trying. Trying means translating the idea into a visible, tangible form and manipulating it with the laws of physics (or at least the laws of computing) re-enabled. This is where things get interesting. What was vaguely described must now be spelled out. The inflexible properties of time and space will expose inconvenient details that your mind overlooked; dealing with even the smallest of these details can derail your entire scheme – or take it wild, new directions. Trying is a collaboration with Reality.
Until recently, trying was fairly easy to do. If the thing you were inventing was a screen layout or a process flow, you could sketch it on paper or use a drawing program to make sure all the pieces fit together. But what if the thing you are inventing is moving? What if it has hundreds of parts each sliding and changing in a precise way? How do you sketch that?
My first step in the journey to a better way was to move from drawing tools like Photoshop and OmniGraffle to animation tools like Hype and Edge – or to Keynote (which can do simple animations). Some years ago I even proposed a standard “animation spec” so that developers could get precise frame-by-frame descriptions.
The problem with these tools is that you have to place everything by hand, one element at a time. I often begin by doing just that, but when your interface is composed of hundreds of shifting, spinning, morphing shapes, this soon becomes untenable. And when even the simplest user input can alter the course and speed of everything on the screen, and when that interaction is the very thing you need to explore, hand drawn animation becomes impossible.
To try out new designs involving this kind of interaction, you need data-driven animation – which means writing code. This is a significant barrier for many designers. Design is about form, color, balance, layout, typography, movement, sound, rhythm, harmony. Coding requires an entirely different skill set: installing development environments, converting file formats, constructing database queries, parsing syntaxes, debugging code, forking githubs.
A software designer needs a partial grasp of these things in order to work with developers. But most designers are not themselves coders, and do not want to become one. I was a coder in a past life, and even enjoy coding up to a point. But code-wrangling, and in particular debugging, distracts from the design process. It breaks my concentration, disrupts my flow; I get so caught up in tracking down a bug that I forget what I was trying to design in the first place.
The next stage of my journey, then, was to find relatively easy high-level programming languages that would let me keep my eye on the ball. I did several projects using Processing (actually Processing.js), a language developed specifically for artists. I did another project using Python – with all coding done on the iPad so that I could directly experience interactions on the tablet with every iteration of the code.
These projects were successful but time-consuming and painful to create. Traditional coding is like solving a Rubik’s Cube: twist and twist and twist until order suddenly emerges from chaos. This is not the way I want to play or try. I want a more organic process, something more like throwing a pot: I want to grab a clump of clay and just continuously shape it with my hands until I am satisfied.
I am not the only one looking for better ways to code. We are in the midst of an open source renaissance, an explosion of literally thousands of new languages, libraries, and tools. In my last blog post I wrote about people creating radically new and different languages as an art form, pushing the boundaries in all directions.
In “The Future of Programming,” Eric Elliott argues for reactive programming, visual IDEs, even genetic and AI-assisted coding. In “Are Prototyping Tools Becoming Essential?,” Mark Wilcox argues that exploring ideas in the Animation Era requires a whole range of new tools. But if you are only going to follow one of these links, see Bret Victor’s “Learnable Programming.”
After months of web surfing I stumbled upon an interesting open source tool originally designed for generative artists that I’ve gotten somewhat hooked on. It combines reactive programming and a visual IDE with some of Bret Victor’s elegant scrubbing interactions.
More about that tool in my next blog post…Possibly Related Posts:

After wearing the Fitbit Surge for seven weeks, I developed an ugly skin rash. So, I took a break and let my skin breathe for a while.
I’m all better now, thanks for asking.
For most of the year, I’ve been test-driving various fitness bands and super watches and journaling my impressions here as one man’s research. After all, wearables are, and have been, a thing for a while now. So, I need to know as much as possible.
If you’re scoring at home, that’s 18 weeks with something on my wrist, a lot for me after 23 years, give or take, of nothing on my wrist; I’m not really a watch guy.
Physical bands aside, I was also tracking and quantifying myself, my fitness and general activity data and my sleep data. I’m a fan of the quantified self and better living through statistics and math. Looking at raw numbers forces introspection that can be very revealing, in good and bad ways.
Anyway, before I put on another device, I decided to capture the pros and cons of not wearing one, at least in terms of what was missing when I had a naked wrist.
Not having something on my wrist all the time is pro enough. I generally don’t like encumbrances, and having my wrist free again is nice.
Typing on a keyboard is another plus. I still don’t know how people with watches do it. A guy I used to work with wore a watch, and his Macbook Pro showed the scratch damage it did to the unibody aluminum.
Being free of data collection is liberating, but it cuts both ways. On the plus side, I don’t obsess about my step count. Wearing a fitness tracker has made it painfully obvious that my life is dangerously sedentary.
If it weren’t for running on a treadmill, there are many days when I wouldn’t reach the 10,000 steps magic number.
Why is this a pro? Now that I know, I can adjust accordingly, without a tracker, and I have a general idea of how much activity generates 10,000 steps.
Taking a break from testing has given me time to reflect on the four devices I’ve used without being too close to the one I’m currently testing. When I finish this research experiment, I should take a similar break to reflect.
On the downside, I really got used to having the time on my wrist, which is something I missed when I wore the Jawbone UP24 as well.
Even though I did find myself checking the time as a nervous habit, the utility outweighed the nervous tick.
I really miss the phone and text notifications that the two super watches, the Basis Peak and Fitbit Surge provide.
On the data collection side, I find myself needing to be pushed by numbers. It’s weird, I know; I’ll recognize something that generates more activity, like walking vs. driving, but I need the extra push to do it.
I also miss my morning data review. It became routine for me to review my night’s sleep and browse through my data each morning, my own a personal, daily report.
Now that Google has Your Timeline for Maps, you can begin to see the value of aggregating data summaries; yes, it’s creepy, especially the implications of kismet or whatever the opposite of that is, but I remain in the optimistic camp that hopes to correlate and improve based on personal data sets.
Anyway, figured since I’d been sharing my wearables observations, I might as well share my lack of wearable observations.
Sometime in the next few weeks, I’ll get started on a new one. Stay tuned.Possibly Related Posts:

I don’t particularly like protective cases for phones because they ruin the industrial design aesthetics of the device.
Here at the ‘Lab, we’ve had spirited debates about cases or not, dating back the original team and continuing to our current team.
I am not careful with phones, and the death of my Nexus 5, which I’ve only had since October 2014, was my fault. It was also very, very bad luck.
I usually run with a Bluetooth headset, the Mpow Swift, which I quite like (hey Ultan, it’s green), specifically because I had a few instances where my hand caught the headset cord and pulled my phone off the treadmill deck and onto the belt, causing the phone to fly off the back like a missile.
Yes, that happened more than once, but in my defense, I’ve seen it happen to other people too.
However, on July 8, I was running on the treadmill talking to Tony on the phone, using a wired headset. I’ve found the Mpow doesn’t have a very strong microphone, or maybe I wasn’t aiming my voice in the right direction. Whatever the reason, the Mpow hasn’t been good for talking on the phone.
While talking to Tony, possibly mid-sentence, I caught the cord and pulled the phone off the deck.
Unlike the other times, this time, the phone slipped under the treadmill belt, trapping it between the belt and housing, sliding it the length of the belt, and dragging it over the back drum.
I stopped the treadmill and looked under, but it was trapped inside the machine. After sheepishly asking for help, we were able to get the machine to spit up my mangled phone.
Interestingly, the screen is completely intact, which gives an idea of how tough it really is. The phone’s body is sadly bent in an aspect that describes its journey over that drum. Luckily, its battery hasn’t leaked.
The device didn’t die right away. While it wouldn’t boot, when I connected it to my Mac via USB, it was recognized, although it wouldn’t mount the storage like it normally would. Something about the device consuming too much power for USB.
I tried with a powered USB hub, but I think the battery gave up the ghost.
Happily for me, I had recently bought a second generation Moto X on sale, and I’d been postponing the switch.
Unhappily, every time I switch phones, I lose something, even though I keep backups. When my Nexus 4 died mysteriously, I lost all my photos. This time, I lost my SMS/MMS history.
Like I said, I’m careless with phones.Possibly Related Posts:

If you’re involved in enterprise user experience (UX) it will come as no surprise that the humble pen and paper remains in widespread use for everyday business.
Sales reps, for example, are forever quickly scribbling down opportunity info. HR pros use them widely. Accountants? Check. At most meetings you will find both pen and paper and digital technology on the table.
That’s what UX is all about, understanding all the tools, technology, and job aids, and the rest, that the user touches along that journey to getting the task done.
Although Steve Jobs famously declared that the world didn’t need another stylus, innovation in digital styli, or digital pens (sometimes called smartpens), has never been greater.
Microsoft is innovating with the device, h/t @bubblebobble. Apple is ironically active with patents for styli, and the iPen may be close. Kickstarter boasts some great stylus ideas such as the Irish-designed Scriba (@getbscriba), featured in the Irish Times.
It is the tablet and the mobility of today’s work that has reinvigorated digital pen innovation, whether it’s the Apple iPad or Microsoft Surface.
I’ve used digital pens, or smartpens, such as the Livescribe Echo for my UX work. The Echo is great way to wireframe or create initial designs quickly and to communicate the ideas to others working remotely, using a pencast.
Personally, I feel there is a place for digital pens, but that the OG pen and paper still takes some beating when it comes to rapid innovation, iteration, and recall, as pondered on UX StackExchange.
An understanding of users demands that we not try to replace the pen and paper altogether but to enhance or augment their use, depending on the context. For example, using the Oracle Capture approach to transfer initial strokes and scribbles to the cloud for enhancement later.
You can read more about this in the free Oracle Applications Cloud User Experience Innovations and Trends eBook.
Sure, for some users, a funky new digital stylus will rock their world. For others, it won’t.
And we’ll all still lose the thing.
The pen is back? It’s never been away.
