University of Washington Ph.D. student Scott Saponas demonstrated his muscle-movement interface for computer systems, by using it to control a familiar application: Guitar Hero. The system appears to guess finger movements by reading the signals from muscles in the forearm. The result: a true air guitar experience. In the custom Guitar Hero setup, the player can hold frets simply by touching a finger with his thumb, and strum by, well, strumming the air. See it in action after the break!

This is just a demonstration of some experimental technology. It's not specifically a game controller, and Activision won't be shipping electrodes to stores any time soon. This is a presentation for the Association for Computer Machinery's Symposium on User Interface Software and Technology -- the Guitar Hero thing just makes for an impressive show.
