A simple idea.
A gaming keyboard which has pressure sensitive keys. I’m no gamer but I think pressure sensitve keys can come in handy.
The idea with pressure sensitive keys is to let the gamer have more controle than simply on/off keys. Here something else could happen if you press harder.
I can imagine the fun games which can be made and improved with pressure keys.
As an alternative I belive its possible to have keyboard keys which when pressed on the border of the key gives another output. I think one can call it XY-keys. Meaning where you hit on the key matters to the digital output.
