I second Andrei's call for clarity here - I don't understand what you're tilting at.

The best I can do is:

- you contend that behaviours are designed for people, not computers or interfaces or software or widgets
- you contend that to speak as behaviour as an attribute of a system and of a human in close proximity is a contradiction
- you say that one of these is 'forward' and the other is 'reverse' (retrograde?)

A few questions:

1) Why can't we have it both ways, depending on your frame of reference? This way, depending on why you are looking at things, behaviour is an attribute of a person, a widget, software, or the overall system. Could we solve this issue just by declaring (or taking some effort to read in) a frame of reference?

2) What is the view that we flatworlders are continuing to support despite evidence to the contrary?

3) What is it exactly in my post of 20 July 2004 (appended to the end of this message) that is ironic (which I read to mean amusingly self-contradictory; please tell me what your definition of irony is).

4) Do the above questions betray the fact that I've not understood you, or do they show that I'm getting close?

Hypertrophically and mutatedly yours,

The 20 July post:

Dan quoted Nico Macdonald who wrote:

Since we're trying to get clean on terminology here, I'd like to suggest that what Dan and Nico MacDonald are getting at is similar to Don Norman's argument in his recent book, Emotional Design.

Norman muses that design can be successful on three levels:

1. Visceral - something that is just appealing
2. Behavioural - something that works well
3. Reflective - something that you can reflect on and appreciate

For example, I write with a fountain pen. I think that they write smoothly and clearly, so they score high on one aspect of behavioural design. However, they require refilling and cleaning, and can be messy - so they score much lower than ballpoints on other aspects of behavioural design. Reflectively, though, is where they have the most appeal for me - I like the *thought* of writing with a fountain pen. If somebody wants to contribute a nice Mont Blanc pen to my cause, then I'll have a great visceral experience as well.

It is true that a strict focus on behavioural designs - things that work well are easy to use - *can* lead to designs that are boring. They work well, but who enjoys using them? It is also true that there is lots of scientific and quasi-scientific research published on doing behavioural design well.

So, to ease up the burden on the terms we're using around here, I'd like to suggest that it isn't usability that hinders innovation, but the type of usability that optimizes designs only on the dimension of behavioural design. Or rather, it is a one-sided focus on behavioural design (or visceral design, or reflective design) that hinders innovation. Truly innovative designs take all of these things into account and makes decisions about which are most important for a given context. I design devices for pilots to use while flying aircraft - behavioural design holds the trump card, and actually produces the best innovations. Someone else might work in a much more consumer oriented, and marketing-driven domain - then visceral or reflective design might be the keys to innovation.

Does that clarify anything? Any comments to build on this?
