Article: Herbert, W. (2011). “Deadline Pressure Distorts Our Sense of Time.” scientificamerican.com. Visited on October 9th, 2012: http://www.scientificamerican.com/article.cfm?id=looming-deadlines Summary: The perceived difficulty and deadline pressure associated with a task alters our perception of time. In an initial study, subject were presented with a series of tasks of varying difficulty and asked how far away the day of completion felt to them. The tasks that were more complex and work intensive were perceived as being further in the future. To arrive at this result our brains are translating effort into time, assuming that the more difficult tasks must be further away since they will require more work to complete. An opposite effect is encountered when deadlines are associated with the tasks. If subjects are presented with either an easy or difficult task that they must complete by a set date in the future, those with the more complex and effortful task report that the date feels much closer to them than those with the simple task. This effect may sometimes cause us to feel overwhelmed as multiple complex tasks pile up on us, but our skewed perception of time also ensures that we typically complete necessary tasks within the actual amount of time…

RE: Is Pink Necessary?
by Natesh Daniel •
How many different ways can someone describe a color? There is a delightful video titled “Luscious” by the Sappi paper company Off Register. In it, the main character attempts to describe the exact shade of “luscious” she wants printed on paper. “It’s like the inside of a baby polar bear’s ear,” she tells the printer. “It’s a nuclear accident, but there’s no problem with it,” she insists. “It’s like King Kong French kissed you … stop it Kong!” All of the metaphors from “Luscious” have another thing in common: They link disparate ideas, a seductive idea with a dangerous one. This is the problem encountered with Annie Paul’s article “Is Pink Necessary?,” which is a review of the book Cinderella Ate My Daughter by Peggy Orenstein. What color best describes a little girl’s sexuality? But little girls have no sexuality, one may protest. Research indicates they do, that children identify with external signs to determine their sex. What then is the hue of sparkly tulle and chiffon? What is the color of a kiss blown from the palm of your hand or a coyly twirled finger in softly dimpled cheek? From the viewpoint of product design, the article is better contemplated as a…

Optical Illusion — Peripheral Vision Distorts Faces into Grotesque Masks
by Olga Werby •
Here’s an interesting optical illusion — by focusing on the center point of the image and using peripheral vision to observe the faces, the perception of the faces changes drastically, making what we culturally consider “beautiful people” into grotesque masks. In particular, watch the eyes. The eyes seem to grow in size and in proportion to the face. The effect in more pronounced with brown eyes.

Where to post the “OK” Button on the Screen?
by Olga Werby •
I have very strong opinions about where on the screen the OK or NEXT or SUBMIT buttons go in relation to CANCEL. Without giving it away, I’m going to walk through the design decision tree and provide a lot of references for both sides of the issue — yes, there are strong feelings about the right versus the left position choice. I’m not alone! Passive versus Active Buttons Active Buttons are the ones that advance the action to the next level. Passive ones return the users to previous state, negate the action sequence. OKAY, OK, NEXT, SUBMIT, ACCEPT, GO are all active buttons. CANCEL, BACK, PREVIOUS are action that reverse forward momentum and push the user to places they’ve been before. HELP and INFO sidetrack the user and distract from forward thrust of activity. In general, product designers want to move the users toward their goals — thus we want the perceptual focus to be on the action buttons. We want to make sure that users fist see the way forward, and then click on the right button that propels them forward to completion of the task. All distractions and side movements should be downplayed with Interface Design with the…

Alternative Haptic Interface for 3D Animation and Drawing
by Olga Werby •
Qumarion built a prototype of a mannequin input device for intuitive 3D manipulation. For many years, artists used little wood manikins to help them with perspective and body positioning. 3D artists also used them for references, but there was no way translate directly from haptic manipulation of a little wooden figure into x, y, and z position in virtual space. Now there is:

Design Solution to Real World Problem — Speeding!
by Olga Werby •
Knowing something about behavior, visual processing, and human nature, designers can nudge users into doing the right (or in this case, lawful) action. Speeding is a problem all over the world. People are notorious for underestimating the real amount of time it takes to get places they need to be. Traffic congestion, car problems, detours, and other (un)foreseen events can make a huge difference in time variability of getting from one place to another. The problem, though, is that we can’t really force people to leave on time or drive the speed limit when the drivers think that no one is looking. So with the law on our side, we can create other ways of forcing people to behave lawfully by changing environmental conditions and relying on human nature not to do what’s right, but to do what they think they have to based on circumstance. Here are a few creative ways of solving the speeding problem on our streets. Using Visual Processing Errors to Slow Traffic Canadian drives misdiagnose the problem and try to drive straddling the “hole” in the road. Everyone is successfully slowed down. The Fake Traffic Cop Threat as a Speeding Deterrent In general, people tend…

Special Preview: Wearable Computing (Steve Mann)
by Olga Werby •
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…
