A Large Touch Surface Brainstorm
April 23, 2011
Something I was thinking about was what if you were to build a surface that had fast moving linear sensors on the side. These sensors could be moved maybe with a stepper motor and a timing belt. So you have a sensor moving in the x direction and one in the y direction. Now you should be able to put your finger on this surface and the sensors would detected it. The x and y coordinates could be figured out and boom, you have a large touch surface. Maybe these sensors could be IR range sensors, or a laser and photo cell. I think it could be a fun idea to play with if I could get the sensors to move fast enough. Once the sensors found your finger, they would then make minute movements to follow your finger. This touch surface could then be used to control a robot with gestures.
Practical? Crazy? Not going to work? Already been done?
