Patent ID: 8471868

Claim:
One or more non-transitory computer-readable media having computer-executable instructions embodied thereon for performing a method of providing a gesture-controlled user interface with a communication device that includes a microphone array and a laser projector, the method comprising: receiving one or more microphone-array signals from the microphone array communicating a representation of one or more sound waves received from one or more transducers that are positioned remotely from the communication device and are capable of being removably attached to a user and that are utilized by the user to perform a gesture comprising moving one or more fingers in the outline of a letter or a number; performing calculations on the one or more microphone-array signals received to generate two or three dimensional coordinates of the one or more fingers making the gesture; comparing the coordinates to gesture patterns in a data store using a best-fit algorithm; and identifying the gesture from matching gesture patterns in the data store and retrieving the associated meaning from the data store.
