Publication number: 20120016604Abstract: 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.Type: ApplicationFiled: May 16, 2011Publication date: January 19, 2012Applicant: Sonavation, Inc.Inventors: Richard Irving, Omid S.
