Intuition, Pleasure and Gestures

Cooper article: "Intuition, Pleasure and Gestures"

Intuition:

    There you have what people really mean by "intuitive:" easy to explain,     powerful in its implications, impossible to forget. You get that through systems     that possess a clear, coherent internal logic that feels natural and obvious.     Of course, it can take hard work to figure out those "natural and obvious"     behaviors; we interaction designers call that work "interaction design."

Pleasure:

    I believe that this hits us at a deep, animal level. Just as we get pleasure     from the form and tactility of good industrial design, we get pleasure from     good interaction design, both as we learn it and as we work with it.     Learning things that make sense, working with tools that work right; these     things make us East African Plains Apes happy right down to our DNA. So instead     of saying "intuitive" or "easy-to-use," at Cooper we often     talk about designing interactive products that deliver power and pleasure     to the people who use them.

Gestures

    I believe that part of why I enjoy it so much comes from something we don't     get to do much when working with computers and other interactive tools: I     do the gestures from muscle memory, rather than cognitive memory, just like     I do with my typing on my computer keyboard. Most of the time tools that run     on software tax our cognitive capacity but leave the intelligence that lives     in our bodies relatively untapped, which makes us East African Plains Apes     a little uncomfortable; using those gestures makes me a happier animal.
