Special Preview: Activity Theory

Crisis Mapping Illustration

Once again, we get an early preview of the next chapter of Interaction-Design.org textbook: Activity Theory. The author of the chapter, Victor Kaptelinin, did a wonderful job of summarizing decades of research in educational psychology, cognitive science, and HCI — from Vygotsky to Moran. If you’re unfamiliar with the theories, research, and thinking that brought us to present day HCI design, this is a great place to start (and includes all of the references to the relevant literature). Adopting an activity-theoretical perspective has an immediate implication for design: it suggests that the primary concern of designers of interactive systems should be supporting meaningful human activities in everyday contexts, rather than striving for logical consistency and technological sophistication. While this chapter focuses mainly on human computer interaction (HCI), I would argue that we need to be broader: we need to focus on product design. And as always, I mean product to be interpreted in a very broad sense. We are moving rapidly into a world where everything we touch is a computing device. Today, I Twitted that my washing machine is an ICT device — the new ARM chip is small, requires very little power, and will be incorporated into everything.…

Emotional Scaffolding

Processing emotions takes time and energy. Part of the working memory is taken up by analyzing the emotional state of others, environmental stresses, personal feelings, and anxiety. Since working memory is an extremely limited resource, anything that takes up space there without our bidding (against our will) takes away from our ability to think through situations, to problem solve, and to make well-reasoned decisions. Instead of thinking, we are using up the working memory for processing emotions. Sometimes, emotions are just the right thing to focus on — to pay attention to. How does this painting makes me feel? Do I like this person? This music feels good… But if you are taking a math test, focusing on how much you really hate test-taking takes away from your ability to take the test. It is very common for individuals to “get” the subject matter, but fail the test. Some people are good at dealing with anxieties and some have trouble controlling their attention controls away from fretting. That’s one of the reason some educators are talking about doing away with summative assessments (final exams) in favor of continuous assessment (assessment as part of learning) — the on-going observation of students’…

Special Preview: Philosophy of Interaction and User Experience

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…

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…

Special Preview: Social Media by Thomas Erickson

Interfaces.com was given a free advanced preview of Thomas Erickson’s report and videos on social computing. The videos are very well produced and provide an interesting point of view and good insights on social media. Below are few of my notes based on the video content and ideas discussed on this blog in the past (my former students should find these familiar). Social Media Definitions & Ideas Social Computing: this is really about groups working together using ICT (Information Communication Technologies). I think this is a broader definition then the one offered by Thomas Erickson, as it includes all forms of ICT. Social Scaffolding: we all have a set of social scripts — culturally-specific, socially constructed norms of behavior — that help us navigate group interactions and allow for self-organization of crowds, at least shot-term and for a limited goal (like crossing the street). [Please watch Dr. Erickson’s example of street crossing in “Video 4.3: Social Computing video 3 – Face-to-face Interaction as Inspiration for Designing Social Computing Systems”.] Product design needs to create opportunities for social interaction — these scaffolds have to be built into the system: meeting spaces, places to sit down, well-lit areas, easy communication tools, games,…

Fun, Functionality, Flow: the 3 F’s of Product Design

Good product design—design that solves a real need; design that considers the strengths and weaknesses of the user; design that stands the test of time and cultural fads—always incorporates the the 3 F’s: Fun, Functionality, and Flow. It’s easy to talk about the 3 F’s in abstract, but I thought taking a concrete example of a bicycle would be more productive. A bicycle is a designed object that satisfies a real need, does so in way that brings joy to its users, and the act of riding results in flow experience for many. The old “Liberator” poster tries to communicate all 3 F’s to the potential buyers of its products: liberator means freedom to move, real functionality; the woman warrior communicates power and fun—you will feel the way she looks! It’s exhilarating! Notice the high heels and the beautiful vista (with a rough terrain) and a kid pointing at the riders with envy. These posters, old advertising ads for bicycles, try to communicate the same: it’s fun, functional, and exciting to ride a bike. Ride, and look good. Ride, and be the center of attention. Design for Fun So what makes a particular design fun? It seems that one of…

The Haptic Feel of Books versus eBooks

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…
