DIY multitouch interface

by

This is uncharacteristic for this blog, but that just goes to show how impressed I was by this simple bit of tech. Take

  • One cardboard box
  • One sheet of paper
  • One sheet of perspex
  • Some tape
  • A webcam

You get a fine multitouch interface! It works on the principle that your fingers create darker dots, and that the webcam picks up on these. You’ll need to download the relevant software, which is currently Windows only in binary, though you can compile yourself (with varying success according to the forum).

Fantastic work guys!
