This is a naive idea.

Unfortunately, all the typing I did Researching led me to develop occasional episodes of repetitive strain injury. It gets really hard to type at times, sometimes I just have to give up entirely. 

It is amazing how much we rely on the mouse and keyboard to interface with computers.

This led me to try to develop a glove, that would sense motion of the fingers. You would then softly touch a keyboard layout printed on a piece of paper, and the glove would relay the pressed keys to the computer.
