RF TRACKING WITH ACTIVE SENSORY FEEDBACK
First Claim
1. A system for providing sensory feedback to a wireless device, the system comprising:
- a system controller including a processor configured to receive data representing a physical multi-dimensional position of an object within a physical three-dimensional environment, to correlate, when the data are received, the physical multi-dimensional position of the object to a point of interest registered within a computer program, and to generate haptic data in response to the physical multi-dimensional position of the object being correlated with the registered point of interest; and
an interface, including a radio frequency (RF) transmitter that transmits radio signals with the haptic data generated by the processor of the system controller to the wireless device, to produce sensory feedback.

Abstract
A system includes a wireless device having a radio frequency (RF) receiver, an RF transmitter, and means for producing sensory feedback to a user of the wireless device. A position-tracking system includes at least three antennae. The position-tracking system computes a multi-dimensional position of the wireless device using triangulation or trilateration based on time of arrival information from radio signals transmitted by the RF transmitter of the wireless device and received by each of the at least three antennae. A processor receives the multi-dimensional position of the wireless device determined by the position-tracking system, correlates the multi-dimensional position to a point of interest registered with an interactive software program that produces a virtual reality environment, and generates, in response to the multi-dimensional position correlated with the registered point of interest, data configured to activate the sensory feedback producing means of the wireless device.

7. A method of providing sensory feedback to a wireless device, the method comprising:
-
registering points of interest within a software program; receiving radio signals with haptic input transmitted by the wireless device over an RF communication link; transmitting radio signals to the wireless device with timing information acquired from the received radio signals; computing, by the wireless device, a physical position of an object within a physical three-dimensional environment based on the timing information transmitted to the wireless device; correlating the physical position of the object within the physical three-dimensional environment to one of the points of interest registered within the software program; and generating haptic data configured to activate a particular sensory feedback on the wireless device in response to correlating the physical position of the object to one of the points of interest.
