I presented an overview of the Sydewynder application to Sven Travis's Creativity and Computation lecture class today. I've attached the PowerPoint and PDF below (and an OpenDocument presentation can be posted, if anybody wants that).
Also, I've released Sydewynder 0.1.1, which has the option to take screenshots of the apps as they run (useful for putting together the presentation) and a new "Round Robin" sample app that shows how to send a single SMS messages to multiple recipients and multiple messages to several recipient lists.
The latest version of Sydewynder, our mobile application server for the S60, has been released! With Sydewynder, any S60 phone, like the Nokia N80, can become an automated SMS gateway. You can grab version 0.1 off of the SourceForge site.
This new version features:
And these bugs were fixed:
Much thanks for Sven, Colleen, Chuck, Eric, Albert, and Chloe for their support, ideas, and code.
Kitsch causes two tears to flow in quick succession. The first tear says: How nice to see children running on the grass! The second tear says: How nice to be moved, together with all mankind, by children running on the grass! It is the second tear that makes kitsch kitsch.
I was assigned to go into a NYC neighborhood and document what I noticed about the type. What I found, in Chelsea and Hell's Kitchen, was a lot of kitsch, in Kundera's sense of the word. So much of the type in the newest presentations refers back to old industrial or distressed type, but in a way that is knowing and safe. It simultaneously induces a frisson from the decayed and supposedly dangerous in a New York working-class neighborhood, while letting the observer in on the joke.
To reformulate the quote above, the two tears are how nice to be in a tough NYC neighborhood and then how nice to know, together with all mankind, that we are in a tough NYC neighborhood.
This is the newest version of the ScanBand series of arm-measuring devices. This time around, I've made it as narrow as I think it can possibly get. The measuring numbers were turned 90 degrees and laid out side-by-side along the edge. The bar codes are the same size as version 0.4, but I think this is as small as I can make them while still allowing for them to be scanned.

At last, version 0.4 of my ScanBand prototype has rolled off the presses (or, at least, the printer in the lab.) This version tossed out the color strip, which turns out to be less useful than I had hoped. It is also significantly narrower, making it more like existing mid-upper arm circumference measuring devices. There is also a window alongside the scanning window that displays the millimeter measurement in numbers, so that the band is still useful in situations with computers or power.
Even more importantly, the version is able to be print two ScanBands completely on a single 8.5x14 inch sheet of paper, BUT can also (potentially) print out on a continuous roll from a 3-4 inch wide label printer. I'd really like to test this latter scenario in Malawi, since the good folks at Baobab have indicated that this might be a great way to print these out as needed.
Attached to this post is the zip file with the PDF of the most recent version.
When I was a kid growing up on army bases, the most popular game played by kids my age was called "Guns." We would come up to each others' houses, find our friends, and ask them, "Wanna play guns?" And they always would.
Here at the rules for "Guns", as they emerged over a couple of years in my section of barracks:
Players are divided into two teams. The teams are usually, though not always, designated as "US" and "Soviets."
Each player selects a toy gun from the collective neighborhood cache of plastic weapons. It is typically good form to select guns appropriate to one's side (e.g. plastic AK-47 goes to the Soviet side.) Also, the better looking weapons should tend to go to older players.
Version 0.2 of scanband increases the size of the measuring window to 5 mm and adds a colored warning strip to allow for quick diagnosis of dangerously diminished mid-upper arm circumference. The barcode gradient in this might be inverted (snafu) and the strip still needs a numerical readout. Also, a window system that folds over the strip, rather than relying on cut slits, would be easier to fit on patients.
ScanBand v0.2Thursday night marked the first presentation of my thesis work to outside critics. It went well, despite a snafu with the barcode scanner that prevented the ScanBand from displaying its results on screen. As a non-digital user scenario, though, it was fine.
Here's the breakdown of my presentation. I've also attached the PDF of the show and a PDF of the version 0.2 ScanBand prototype, which is made available under the Creative Commons Attribution-ShareAlike License 3.0
For me, the annual New Yorker Style Issue is usually thin on content and long on made-up 15 year olds looking studiously blase about their Burberry togs. But this issue featured an article by Henry Alford called "Solar Chic," where the author user tests a Zegna bomber jacket with removable solar panels in the collar. The solar panel fed a battery in the breast pocket which, in turn, would charge standard 5-volt devices like music players and phones. The piece could almost be a case from the Knight et al. paper.
I've been doing a lot of work on anthropometrics, and I found the articles for this week to be really helpful for my thesis research. I have been thinking about how to measure vital signs on a patient's body in a way that is inexpensive, accurate, and user-friendly, both for the patient and the technician. Equally important, however, is that a measuring device should be wearable, by the authors' definitions, if only for a short time.
In "The Comfort Assessment of Wearable Computers," by James Knight, et al., the authors invented a multidimensional test for describing the feelings of comfort or discomfort for a wearable device. I'm a freak for numbers and hard data, so it's nice to have this tool available to me for evaluating prototypes. I am especially glad to see how the evaluations are broken down, getting rid of the unhelpful, single variable comfortable/uncomfortable and allow researchers to get more toward the point of what actually is making the user uncomfortable with a device.
More specific to the design of the devices themselves, in "Design for Wearability" Gemperle et al. delineated the constraints for device placement, form, allowance of movement, peripersonal space, attachment, and several other considerations. For me, this could work as a checklist as I create new devices and wearables, making sure I've considered all of the problem areas. I especially appreciated their breakdown of good places to site the devices, which helps give me a starting point for how to shape and attach them.
Rounding out the readings, Dunne and Smyth's "Psychophysical Elements of Wearability" dove more into the neurological side of comfort, which I also liked. I have done a bit of work with haptic interfaces before, and the deadening of response to a continuous stimulus is something I've noticed. If you want the user to notice an output, the stimulus must be fresh. On the flip side, if you want the user to not attend to the device, it must be comfortable (that is, it must not irritate the nerves.)
I think the Dunne and Smyth article sums up something for me that I have been thinking about for a while. For a wearable to be successful, in my opinion, it must be peripheral. In their terms, it must be something that is subconsciously processed but not attended to. Important input from the wearable may be perceived by the user and later attended to, but it should otherwise fall into the background noise of the rest of the world.
With all this in mind, I conducted a little experiment with some equipment I picked up at Modell's, a local sporting goods chain store. I picked up a set of Adams Forearm Pads, Adams Football Pants, Adams Football Thigh Pads, Adams Neck Roll (flat contour), a pair of Trace Hand-Guard Plus, Nike Dri-FIT Sliding Pad, and a Nathan L.E.D. Wrist Runner. I put on the pants with the thigh pads inserted, put the forepad on my left forearm, the sliding pad on my upper right arm with the thickest part on my tricep, put the neck roll loosely over my shoulders, and put the hand guard on my left hand. Then I performed ordinary tasks to see how I reacted to these additions to my body in daily life.
