Scratch Input

We conclude with a study that shows users can perform six Scratch Input gestures at about 90% accuracy with less than five minutes of training and on wide variety of surfaces.

As far as low-cost surface computing goes, scratch input takes the cake; it could find a million uses in ten-foot interfaces around the home. But will it? Doubtful.

Sure would be fun to control Sous Chef from across the room like this, though.

Gestures include a double tap, an X, an O with a line through it, an i, an F, and a Y.
