RF tracking with active sensory feedback
First Claim
1. A system for providing sensory feedback to a wireless device, the system comprising:
- at least three antennae receiving radio signals transmitted by the wireless device, the radio signals conveying haptic input provided by a user of the wireless device;
a radio frequency (RF) receiver coupled to that at least three antennae to receive therefrom the radio signals transmitted by the wireless device, the RF receiver acquiring from the radio signals the haptic input and timing information to be used to compute data representing a physical multi-dimensional position of the wireless device within a physical three-dimensional environment;
a system controller including a processor configured to receive the haptic input from the RF receiver and the data representing the physical multi-dimensional position of the wireless device within the physical three-dimensional environment, to correlate, when the data are received, the physical multi-dimensional position of the wireless device to a point of interest registered within a computer program, and to generate haptic data in response to the haptic input and to the physical multi-dimensional position of the wireless device being correlated with the registered point of interest; and
an 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.
