I am always thinking about eye controlled robotics but don't have many skills in computer controls and programming step motors.

I did my son to assemble a sort of toy robotic arm a couple of years ago that I could with my head movement so could be controlled with eye's but it does not use step motors and the control screen takes all of the computer screen and can't be made smaller.

You could pick things like tissues, small drinks etc up and move them near you.

Anyway, I was watching Click episode "Domo Arigato, Mr Roboto" it had some assistive technology but nothing over suitable for us.
