Cultural Differences through Time

by  • 

Bottle of Heroin (1890-1910) by Bayer, sold as a non-addictive substitute for morphine

There’s been a shift in our culture (at least in US) towards seeing medication as a sign of weakness from one of alleviation of suffering that predominated out society some 100 years ago. Some people I know are even proud of the fact that they’ve never taken a painkiller or were treated for cough. Stoicism became a virtue all in itself — “I’m a good person because I don’t take medicine, preferring to suffer the illness and/or the symptoms of the disease.” And it’s not just the patients that feel this way. Medical professionals routinely prescribe to the “complain 3 times” rule: their patients have to mention being in pain on multiple visits prior to getting a prescription that would deal with it. A friend told a story of a doctor visit during which he was told that “he didn’t want to appear to be complainer.” Several weeks later, he was having back surgery and remains in a wheelchair to this day, a decade later! How did we get here? This is a very complicated question, but it might help to examine how things use to be. Below are medications as they were packaged and sold all over America in the…

Special Preview: Philosophy of Interaction and User Experience

by  • 

A person uses a piece of software, a Web site, or any other product — “virtual” or “real” — to achieve a goal. The design of interaction with these products can either help or form obstacles that interfere with the realization of that goal. A product is easier to use when its interaction is designed to meet the needs of its intended audience. Product designers who consider those needs produce far more effective interaction solutions than those who base their designs on aesthetics or business needs alone. But how does one go about “considering” user needs and then come up with a design solution that works? Oscar Wilde famously said: The pure and simple truth is rarely pure and never simple. Pure and Simple design is similarly rarely pure and never simple to develop. I my class, Cognitive tools for Product Designers, we explore what users bring to usability. We all arrive at the scene with different baggage — our experiences, education, perception, memory, and so on are unique to each of us. No two individuals interpret an experience in exactly the same way. While this sounds daunting, we shouldn’t give up on design all together. We all have some…

End-User Development (EUD) Educational Preview

by  • 

This is an interesting collection of videos and background materials on End-User Development — situations when end users design and develop software for their own use. If you’re old enough, you would remember BASIC and HyperCard — tools that let anyone develop simple games and applications. A great example is “Spelunking” game totally developed in HyperCard (these guys when on to develop “Myst”!). I’ve made a few games like this myself. And of course FileMaker is another system that allows application development by the end users — we have one for time tracking. There have been many many others, and unfortunately, many of them are now gone. The discussion on what happens when end users develop for themselves is fascinating. Most times, these users are experts in their own fields and are not software developers (some have no and some have little formal training). Thus there are cultural differences between “real” programmers and end users that take up programming to achieve their own goals, often because they can’t find what they need out in the world. These end-user designed products have strengths and they also have many weakness. In particular, these products are tightly focused on the needs of those…

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…

Design for Emotion, for Empowerment

Aimee Mullins legs collection

I use a cane to get around, a consequence of an unfortunate encounter with a taxi many years ago. I have many different canes (each heel size, for example, requires its own cane). All are cool. Some have animal carvings, some have silver, some have gold, some are complex in design, some are very Deco in style, and one has a sword (another a compass and a secret compartment). I get stopped on the street all the time — people love my canes and always comment. I was even told once that my limp is sexy — whatever… What I don’t have is an “old woman” cane — the kind you buy at a pharmacy. I’m just not that old, and plan never to be that old. I want funky, I want things that match my outfits and my moods. And I want them functional: the right hight, the right feel of the cane handle, the stability of the tip, the light weight, the structural security. I want it all and I want it sexy. Cane is a product — a very personal one. But most are stuck with poorly designed, boring, ugly, you-make-me-feel-like-an-invalid cane. Why? Aimee Mullins is a…

Intel i5 Core Commercial: When a company just doesn’t get it

by  • 

Sometimes, a company just doesn’t get it: it’s not about what a product can theoretically do, but what it can do for the user. Intel has a history of making a particular type of commercials — “the power inside” commercials, I call them. Intel marketing people use the following mental model: people/men like muscle cars; people like powerful things; thus if we emphasize the power “on the inside” people would like our computers. And so their current commercials for Intel i5 Core look like this: So what’s wrong with this? It’s all about them, it’s not about me. I don’t care what’s inside the machine, I care what it can do for me. Or, more accurately, what I can do with it. It’s about my performance. Imagine going to a car lot and the car salesmen tells you: “It got huge pistons. I mean HUGE. You’ve got to see those pistons!” Perhaps some car buyers would get inspired by such language, but I bet most would find it puzzling. Why should I care? Does it drive well? What’s the performance like? Maneuverability? Intel’s commercials about its chips are just like a car manufacturer’s fetish remarks about pistons. Sure some would…

Socially Constructed Beliefs

by  • 

American Academy of Pediatrics (AAP) came out with a strong recommendation against the use of bumpers in cribs. The September 2007 issue of The Journal of Pediatrics examined deaths and injuries attributed to infant crib bumper pads: “Twenty-seven accidental deaths reported by medical examiners or coroners were attributed to bumper pads. The mechanism of death included suffocation and strangulation by bumper ties. Twenty-five nonfatal injuries were identified, and most consisted of minor contusions. All retail bumpers had hazardous properties.” AAP has finally announced that it is formally against bumpers. That certainly took a while. And, amazingly, the bumper pads are still for sale by all major baby room outfitters, and parents are still buying them and using them with their beloved offspring. Why? Why would parents knowingly endanger their children? This is an interesting case of Mental Model Traps, Mirroring Errors, and Cognitive Blindness. Mental Model Traps Let’s start by Mental Model Traps that parents fall into in this particular case. To do this, we need to back up in time a bit. The design of children’s beds had undergone considerable evolution over the last few centuries. Cribs used to be just large baskets with tightly woven sides. The weave…
