Abstract: The technology disclosed addresses these problems by supplementing optical gesture recognition with the ability to recognize touch gestures. This capability allows the user to execute intuitive gestures involving contact with a surface. For example, in low-light situations where free-form gestures cannot be recognized optically with a sufficient degree of reliability, a device implementing the invention may switch to a touch mode in which touch gestures are recognized. In implementations, two contact microphones or other vibratory or acoustical sensors, that are coupled to an optical motion-capture and are in contact with a surface that a user touches, are monitored. When the contact microphones detect audio signals (or other vibrational phenomena) generated by contact of an object with the surface that the user touches, a position of the object traveling across and in contact with the surface is tracked.
