Patent number: 9823760Abstract: A source audio signal to be rendered by a touch input medium is received. A transmitted signal to be propagated through the touch input medium is sent. The transmitted signal includes the source audio signal and a touch location detection signal. An event is indicated, where the touch input medium has been contacted at a location on the touch input medium by a touch contact such that rendering of the source audio signal by the touch input medium is affected by the touch contact. The location of the touch contact on the touch input medium is determined by analyzing a disturbance by the touch contact on the rendered touch location detection signal. At least a portion of the source audio signal is modified based on an expected effect of the contact on the touch input medium determined using the indication of the detector.Type: GrantFiled: June 4, 2015Date of Patent: November 21, 2017Assignee: Sentons Inc.Inventors: Samuel W.
