TAFFI

By Dave on December 26, 2006

TAFFI (Thumb And ForeFinger Interface) is, in the words of its creator, “an inspired hack”. Andy Wilson of Microsoft Research wrote an algorithm that uses a cheap USB camera connected to his PC to allow him to control the computer with his hands held over the keyboard. No mouse or other pointing device; the software simply recognizes when his thumb and forefinger close together to make a loop. Watch the video in the link above, or here.

I’m no programmer, but this just strikes me as brilliant. Simple and brilliant.

A pdf of Andy’s paper on the subject — “Robust Computer Vision-Based Detection of Pinching for One and Two-Handed Gesture Input” (catchy title, eh) — can be downloaded here.
