US Patent 9390726 Supplementing speech commands with gestures

Described is a system and technique to supplement speech commands with gestures. A user interface may be improved by providing the ability for a user to intuitively provide speech commands with the aid of gestures. By providing gestures contemporaneously with a speech command, the user may delimit the commencement and end of a command thereby allowing the system to provide an immediate response. In addition, gestures may be detected in order to determine a source of a provided speech command, and accordingly, user specific actions may be performed based on the identity of the source.
