Patent ID: 8570274

Claim:
A system for sensory feedback control, comprising: an ultrasonic receiver device to: generate a three-dimensional ultrasonic sensory space one centimeter or more beyond the receiver device and the ultrasonic sensory space is wider than any size of the receiver device, defining a plurality of concentric boundary regions within the three-dimensional ultrasonic sensory space that are each associated with a wand location and a sensory feedback response, and detect and report the location and position of the wand in the three-dimensional ultrasonic sensing space from peak-detection of directed ultrasonic signals with high-resolution positional accuracy; and an indicator communicatively coupled to the ultrasonic receiver device, the indicator providing a sensory feedback response associated with the location and position of the wand in the three-dimensional ultrasonic sensory space, wherein the sensory feedback response is visual, auditory, or haptic.
