Navigation device providing sensory feedback
First Claim
1. 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, anddetect 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.

Abstract
A device and method is provided for sensory feedback control during touchless navigation of a user interface. The navigation system permits touchless user interface control via a wand pointing device and a receiver device. The wand is used to identify points of interest in three-dimensional space via a wand tip. The wand tip does not contain any electronics or sensors and permits precise access measurements. The wand can also be affixed to objects to track their movement and orientation within proximity of the receiver. In one arrangement, the sensory feedback provides a visual indication of the wand'"'"'s location and orientation through the user interface. Other embodiments are disclosed.
