Bringing Sketching Tools to Keychain Computers with an Acceleration-Based Interface

Golan Levin and Paul Yarin
8 January 1999

We report the use of an embedded accelerometer as a gestural interface for an extremely small ("keychain") computer. This tilt- and shake-sensitive interface captures the expressive nuances of continuously varying spatio-temporal input, making possible a set of applications heretofore difficult or impossible to implement in such a small device. We provide examples of such applications, including a paint program and some simple animation authoring systems.
