Just a suggestion that someone come out with a pressure sensitive
keyboard. It would sense the direction and how hard I am hitting the
keys on the keyboard.
Imagine the possibilities.
Just what direction did you plan on pressing them, and what
result did you hope for, if you were to press the "m" key
leftwards instead of down?
A keyboard is a standardized human interface, you would have
to have a very specific need for such a control method and
it would seem most likely that an even more suited
controller could be made that didn't try to integrate a
keyboard into itself, too. Alternately, many keyboards have
special function, programmable keys. Is it really good to
make a lot of keys perform several functions instead of
dedicated keys? IMO, most people would rather not have to
use multi-key combinations for a function rather than one
dedicated key or a standard way of accessing the secondary
function like the shift or control key.
