In regards these principles, I’d suggest there are three things we really need to care about. These aren’t categories, they’re just things that strike me as important. They are:* Assumptions * Attention * Affordances
Now they bleed into each other terribly, and if there are any psychologists in the room then I apologise in advance. I’ve done the typical technologist thing of appropriating a word and twisting it until it means something that’s useful for me, but has only a tenuous relationship to its original meeting.
A big hello to all the “information architects” who are here, by the way.
So what I’m going to do, hopefully, is point out a few places where human perception – and I’m going to concentrate on visual perception – is filtered an augmented by these three things. Make of it what you will, and maybe I’ll even have a conclusion at the end. We’ll see how brave I’m feeling.
Since we started on assumptions, I’ll carry on a bit. I’ve actually got the most examples around this bit too.
