Here is an amusing video about “beliefing (or not) in UFOs” which shows our boundaries of imaginative power and that optical illusions should be known as brain failures.
In my opinion we have to recognize these things “mental / perception problems” when designing human machine interfaces, in a way that new technology doesn’t confuse the users.
Beside the thoughtful aspects concerning human life:
Are we able to learn anything for human computer interaction based on the human brain workings (right hemisphere = parallel processing & left hemisphere = serial processing)?
Here is some interesting stuff by combining pen input with multitouch (which gives the ability to realize “tools“):
Seems to be developed in extensive technical view. For example, (initially) it is not intuitive for the user to copy an image by holding the one hand down and drag the other with the pen (starting in video at about 1min). So some improvement work in human view on this good idea is still pending…
On the way to “Terminator”!?!
