Title:
METHODS AND SYSTEMS FOR POINTING DEVICE USING ACOUSTIC IMPEDIOGRAPHY
Document Type and Number:
WIPO Patent Application WO/2011/143661
Kind Code:
A3
Abstract:
Invention includes a novel pointing device which uses acoustic impediography as a means to locate the position of finger and then uses the said location to control the position of a cursor on a computer screen. In addition, while the finger is touching the sensor the touch- pressure level can be estimated via statistical data evaluation, as average brightness decreases with increasing touch-pressure providing a means for gesturing. This new device has the advantage that it can double as a biometric identification device for verifying the identity of the computer's user.
