Patent ID: 7148879

Claim:
A method for controlling an electronic device comprising: receiving one or more bioacoustic signals conducted by finger bones to one or more piezo-electric contact materials (microphones) at a wrist location, each signal related to one or more hand gestures including finger movements; determining the identity of the one or more hand gestures based on a positive correlation between the received signals and predetermined hand gesture data; and selectively issuing one or more commands associated with the identified hand gesture for activating one or more functions of the electronic device and wherein the one or more hand gestures includes a first gesture which reflects contact between a thumb and an index finger of a human hand, a second gesture which reflects contact between the thumb and a middle finger of the human hand, a third gesture which reflects contact between the thumb and a ring finger of the human hand, a fourth gesture which reflects contact between a finger and a fingernail, a fifth gesture which reflects non-contact between one or more fingers, a sixth gesture which reflects contact based on a displacement threshold and seventh gesture which reflects contact based on a pressure threshold.
