TSA: the Good, the Bad, and the Ugly

by  • 

There has been a lot of stories lately about the Transportation Security Administration (TSA), and most have been less than flattering (to say the least). How can an agency that was designed to “serve and protect” the citizens of the United States from harm evoke such wrath from ordinarily shy and non-vocal travelers? This blog is about product design, and so my analysis of the situation will treat this as a failure of product design. Where are the failures? Mistake #1 TSA Conceptual Design: Blocking There are bad guys out there that want to do us—citizen travelers from US—harm. There are the box-cutter carrying terrorists, the shoe-bombers, the liquid explosives bandits, the underwear-bombers, the printer cartridge explosives engineers. TSA installed airport security measures that would counteract each of these threats as they revealed themselves. The basic conceptual design strategy here is blocking: identify a threat and find an effective block. This is a strategy based on hindsight: if we knew that people could sneak bombs in their underwear, then we would have had a way to block it. We didn’t know, but now we do, and so we created systems to block this threat in the future. TSA Game Plan: Escalating…

e-Waste & Product Design

by  • 

I just came across a very interesting video by Annie Leonard. She’s been making little, approachable documentaries that explain difficult to understand issues—e-waste being one of those. Here’s her latest: The Story of Stuff. This is the story about how stuff gets designed, made, distributed, and then trashed. The Story of Bottled Water. This is the story about drinking water and the marketing of bottled water.

Sizing Up Consciousness by Its Bits

by  • 

Zimmer, C., (2010). “Sizing Up Consciousness by Its Bits.” NYTimes.com. Visited on October 3, 2010: http://www.nytimes.com/2010/09/21/science/21consciousness.html Carl Zimmer’s article “Sizing Up Consciousness by Its Bits” for The New York Times seeks to introduce and explore a relatively new area of research into human consciousness. In interviews with the medical researcher Dr. Giulio Tononi, the article discusses current and past conceptions of consciousness and its’ implications for our interactions with each other and with our environment. Given the importance of consciousness in everyday human life, one would reasonably assume that at this time science would have a detailed understanding of consciousness and how it functions. This is not the case, however. Despite centuries of philosophical debate, medical research, and technological development, humans are largely in the dark, so to speak, about what creates and maintains the spark of consciousness. In the context of our currently vague understanding, Dr. Tononi’s research proposes a novel way of conceptualizing consciousness. Dr. Tononi’s goal is to apply the theories of informational networks to the human brain, in a method he terms “Integrated Information Theory.” This theory, hereafter referred to as IIT, seeks to understand the human brain as an integrated network of nodes (neurons in…

More is always better – Or so most think!

by  • 

Tugend, A., (2010). “For the Dishwasher’s Sake, Go Easy on the Detergent.” NY Times Online. Visited on November 04, 2010: http://www.nytimes.com/2010/03/13/your-money/13shortcuts.html   If dishwashers do not seem to be doing their job or if your clothes are not coming out as soft as you’d like them to, or if these machines break down easily, it is most likely due to “user error.” We throw in multiple fabric softener sheets because more is better. More isn’t better in this case! The excess sheets liquefy when the dryer gets hot and gum up the dryer. Most people use ten to fifteen times the amount of soap they need. This excess soap is detrimental to the life of the machines.   This article has some clear implications for interaction and interface design.  User errors are likely to happen. Even if you have a manual with detailed instructions, the chances of somebody reading that manual are very slim. Even if they read it, they are still likely to err. How can design inculcate the right usage in the user? In this case, what can design do to prevent errors resulting from the ‘More is better’ p-prim?    Possible Interaction Design Solutions: Solutions could be…

Thinking About the Future of Reading

by  • 

The Taxonomy of Usefulness We are a family with two Kindles, three iPads, two iPods, and an iPhone. We also have a few thousand old-fashioned paper books stored on bookshelves in every nook and cranny of our home: bedrooms, bathrooms, kitchen, stairs, garage, closets, family room, and any other space and surface that might hold a book or two or ten. We are into reading! And we use our Kindles, iPads/Pods/Phone, and computers to read as well. And while statistically speaking, we make just four data points for four family members, I feel we have something interesting to say about using technology to read. To help me understand my own relationship with reading and technology, I’ve come up with a little Taxonomy of Usefulness. If you’ve been reading this blog (or my books and papers), you’d have noticed that I like to slice up the world into groups sorted by a set of variables that I find useful at the time. Forming categories helps me think—the Cognitive Wheel is a prime example. Taxonomy of Usefulness These variables help derive the value of the electronic reading devices. Ergonomics There are many attributes to consider when describing the ergonomics of a device,…

Language and thought in user-centered design

by  • 

Deutscher, G. (2010). “Does language shape the way you think?”  New York Times Online Edition. Retrieved on October 4, 2010. http://www.nytimes.com/2010/08/29/magazine/29language-t.html This article summarizes the history and the current status of the linguistic relativity hypothesis or the idea that “language shapes thought.” This idea comes in several different formulations. The version on which Deutscher’s review focuses is a cross-linguistic claim that speakers of different languages use different mental representations or processes as a result of having learned different languages as children. A particularly strong version of the cross-linguistic hypothesis suggests that our native language provides us with a basic toolbox of conceptual representation, so if a concept or a mode of thought is not encoded in a given language, its monolingual speakers would be incapable of thinking about such a concept or thinking in such a mode.  For instance, linguistic relativity led to the prediction that people’s perception of differences in color should reflect the way their language encodes color.  This prediction was spectacularly disproven by the discovery that people whose language only has two color terms in its vocabulary perceive and categorize colors similarly to speakers of English, which has 11 basic color terms, plus many non-basic ones (Berlin…

Re “Wine Study Shows Price Influences Perception”

by  • 

Svitil, K., (2008). “Wine Study Shows Price Influences Perception.” California Institute of Technology. Visited on October 4, 2010: http://media.caltech.edu/press_releases/13091 This article is a research study about how the region of the brain called the medial orbitofrontal cortex showed higher activity when participants drank wines at a higher price. A wine tasting study was conducted at the California Institute of Technology and Stanford University. Twenty volunteers tasted five wine samples at different retail prices: $5, $10, $35, $45 and $90 per bottle. The volunteers tasted and evaluated which wines that they found more pleasurable. Two out of five of the wines were the same but one was priced at $10 and one at $90. In the experiment the subjects rated and preferred the $90 priced wine more than the $10, although they did not know that they tasted the same wine. Cognitive Design What does the product do? In this study the cognitive design was a wine tasting experiment. The concept of the research was to experiment on the perception of price on different wines.  The setting was controlled in that the subjects did not know that they tasted the same wine but told that the price was different. While tasting…
