Some of the most interesting glove and hand controllers have come from STEIM, the Dutch center for electronic performance research in Amsterdam. One of the most advanced is Laetitia Sonami's (now at CNMAT, U.C. Berkeley) "Lady's Glove", an extremely dexterous system, with bend sensors to measure the inclination of both finger joints for the middle 3 fingers, microswitches at the end of the fingers for tactile control, Hall sensors to measure distance of the fingers from a magnet in the thumb, pressure sensing between index finger and thumb, and sonar ranging to emitters in the belt, shoe, or opposite arm. This video clip (11.1 MEG MPEG) shows excerpts of Laetitia Sonami performing with this system.
