Special Preview: Wearable Computing (Steve Mann)

by  • 

The next chapter in the Interaction-Design.org tome on human-computer interaction design is now up for an early review to my readers. This chapter takes on Wearable Computing and is written by Steve Mann. Mostly, this is a historical review of Prof. Mann’s experimentations with wearable computing devices, and for those unfamiliar with this subject area, this is an interesting introduction. On the left, you can see an early version of wearable computing: Steve Mann’s backpack based system from the late 1970’s and early 1980’s. But as always, I have a slightly different take on this topic… The Little Mac That Saved My Son’s Life Almost 18 years ago, I went into a preterm labor. At 24 and a half weeks into gestation, this was very scary. At the time, San Francisco Children’s Hospital was pioneering a program for high risk pregnancies (which mine just turned out to be). Two doctors, Dr. Kuts and Dr. Maine, figured out how to use an old Mac SE, a modem, a telephone, a subcutaneous pump, and a belt which measures contractions to allow women like me to stay at home as much as we could (as opposed to spending months in the hospital). Here’s…

Creativity, Perception, and Public Art

by  • 

Coming Unzipped

Art or craft? Creativity or public nuisance? Sometimes, the line between these is so fine, so complex, so fractal, that it’s simply doesn’t matter. The images below span thousands of years in dates of creation. The artists used light and shadow, perspective, and clever geometry of space to add meaning to their work. All showed an amazing amount of imagination, all provide commentary on current events or a point of view. Happy holidays to all! Enjoy! [flagallery gid=3 name=”Gallery”]

Thinking about the Science of Communication and Interaction

Alien Senses

In the Galaxy Far Far Away… What if sentient being evolved on a planet with permanent cloud cover? What if these being never saw stars? Would they still be able to discover the laws of nature? These kinds of hypothetical thinking questions — the Gedankan Experiments, as Einstein put it — are very useful in science. I’ll try to use them here for analyzing product design and communication. So what senses do we need to communicate? And what body appendages are necessary to produce this communication? Note that it helps keep track of these separately. Aroma-bet When I was little, I “designed” a language based on smell: each smell was assigned a character in an alphabet and, strung together in sequence, my smelly letters transcribed into words — the Aroma-bet. There were several problems with this: It was difficult to get an alphabet-worth of distinct odors; Arranged next to each other, the odors started to blend into each other, making “reading” difficult; I got a very bad headache; My mom didn’t like her expensive perfumes used in such a creative way… And I couldn’t remember what letter each smell stood for, requiring the creation of a smell-o-dictionary, which in turn…

The Haptic Feel of Books versus eBooks

by  • 

We’ve traveled to Rome for our family vacation this year, and aside from a few summer reading books that I couldn’t find in an eBook format, we relied on our two Kindles and 3 iPads for our family reading needs. This is the second summer we brought primarily electronic versions of books—”The Count of Monte Cristo” is much easier to read when it fits into your hand and doesn’t weigh a ton… In the days before the Kindle and iPad, we carried an extra suitcase just for books. But there are drawbacks to buying and reading eBooks. Below are some of my thoughts and experiences—the cogitations of a voracious reader. Time & Progress As I was reading my novels, I found myself repeatedly trying to figure out where in the book I was. How far along was I? When is the next natural break (chapter, section end)? How many pages are there to the end of the chapter, end of the section, end of the book? These were not idle curiosities about my reading accomplishments, although when you do finish reading the book version of “The Count of Monte Cristo”, you do have a sense of having read something. An…

Attention Control Errors & Perceptual Blindness

by  • 

Harvard Vision Lab created a few experiments that feature Attention Controls Errors and Perceptual Blindness. Below is one of their optical illusions. Directions: concentrate on the central white dot. Did the colors of the outside dots continue to shift throughout the video? If they stopped when the dots were rotating, then you’ve just experienced Silencing—the lab’s vocabulary for individual’s inability to pay attention to both motion and color shift at the same time. Here, we mostly call it Perceptual Blindness. My Personal Experience with this Illusion: The first time I watched the video, I think the colors stopped shifting…but I don’t really remember—I wasn’t paying attention! The second time, I saw the shift. When I showed the illusion to a colorblind individual, he saw the shift from the first viewing. To read about the complete experiment and to view more illusion videos, please visit the lab: http://visionlab.harvard.edu/silencing/
