True, but even as laymen I think we could be useful. Even a hobbyist
analysis might be better than none at all.

For example we might analyse an interaction process (a user doing
something) and measure the number of mouse clicks, mouse pointer move
distance, swaps between mouse and keyboard etc. Then we could see if
any steps could be simplified or removed. If we feel that comparing
the efficiency of two processes, I guess the difference might be so
small that it's not worth it.

Ok, maybe not the best word, that's why I added the explanation :)

What I meant by this category is how the computer presents information
to the user. For example how well in conveys which actions are
possible, the consequences of these actions, help texts and of course
pure data.

Getting the computer to understand the user is what I tried to
describe with category 1. I also think that everything we talk about
on this list falls within HCI, as it's a rather wide field of science.

Sure, why not :)

I think the problem with experimental UI's is that they only work when
you're using a single application at a time (like you said, with Amiga
screens or on the iPhone). But if you need to stick several apps on
one screen or try to connect 2 apps, where one isn't a plugin designed
specifically for the other, it would most likely turn rather messy.
On the other hand, Propellerheads' Reason is an example where I think
a custom UI really works.

I think screens aren't that far away. We have workspaces already and
I'm advocating that all the junk on the desktop should be removed (and
that functionality added elsewhere), dynamic creation of workspaces
and when I have time I'll finish my gnome-do clone so don't need the
deskbar for everything.
