ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of Endeavor
The present invention relates to computer input devices and more particularly to a wireless computer input system.
2. State of Technology
The abstract of U.S. Pat. No. 4,988,981 for a computer data entry and manipulation apparatus and method by Thomas G. Zimmerman and Jaron Z. Lanier, patented Jan. 29, 1991, provides the following description: “Apparatus is disclosed for generating control signals for the manipulation of virtual objects in a computer system according to the gestures and positions of an operator's hand or other body part. The apparatus includes a glove worn on the hand which includes sensors for detecting the gestures of the hand, as well as hand position sensing means coupled to the glove and to the computer system for detecting the position of the hand with respect to the system. The computer system includes circuitry connected to receive the gesture signals and the hand position signals for generating control signals in response thereto. Typically, the control signals are used to manipulate a graphical representation of the operator's hand which is displayed on a monitor coupled to the computer system, and the graphical representations of the operator's hand manipulates virtual objects or tools also displayed by the computer.”
The abstract of U.S. Pat. No. 5,414,256 for an apparatus for and method of controlling a device by sensing radiation having an emission space and a sensing space by Asaf Gurner and Oded Y. Zur, patented May 9, 1995 provides the following description, “An optical controller is capable of surrounding a player with a radiation screen from a plurality of panels, and enables the player to produce control signals for interface with a controlled instrument such as a musical instrument, a video game processor, etc. The insertion of the appendage of the player can produce a functional control signal. The relative position of the insertion of the appendage can be determined, for example, as a result of the intensity of the reflected radiation in the dispersing radiation screen and adjusted in elevation. The video game processing unit can play either a conventional video game that usually accepts eight functional control signals, or it can utilize the full capacities of the control signals available from the optical controller for enhanced play action.”
The abstract of U.S. Pat. No. 5,442,168 for a dynamically-activated optical instrument for producing control signals having a self-calibration means by Asaf Gurner and Oded Y. Zur, patented Aug. 15, 1995 provides the following description, “An optical controller is capable of surrounding a player with a radiation screen from a plurality of panels, and enables the player to produce control signals for interface with a controlled instrument such as a musical instrument, a video game processor, etc. The insertion of the appendage of the player can produce a functional control signal. The relative position of the insertion of the appendage can be determined, for example, as a result of the intensity of reflected radiation in the dispersing radiation screen. The video game processing unit can play either a conventional video game that usually accepts eight functional control signals, or it can utilize the full capacities of the control signals available from the optical controller. The player can simulate the movements of the video character to experience a more realistic game play action.”
U.S. Pat. No. 5,510,800 for a time-of-flight radio location system by Thomas E. McEwan, patented Apr. 23, 1996 and U.S. Pat. No. 5,661,490 for a time-of-flight radio location system by Thomas E. McEwan, patented Aug. 26, 1997 provide the following descriptions, “A bi-static radar configuration measures the direct time-of-flight of a transmitted RF pulse and is capable of measuring this time-of-flight with a jitter on the order of about one pico-second, or about 0.01 inch of free space distance for an electromagnetic pulse over a range of about one to ten feet. A transmitter transmits a sequence of electromagnetic pulses in response to a transmit timing signal, and a receiver samples the sequence of electromagnetic pulses with controlled timing in response to a receive timing signal, and generates a sample signal in response to the samples. A timing circuit supplies the transmit timing signal to the transmitter and supplies the receive timing signal to the receiver. The receive timing signal causes the receiver to sample the sequence of electromagnetic pulses such that the time between transmission of pulses in the sequence and sampling by the receiver sweeps over a range of delays. The receive timing signal sweeps over the range of delays in a sweep cycle such that pulses in the sequence are sampled at the pulse repetition rate, and with different delays in the range of delays to produce a sample signal representing magnitude of a received pulse in equivalent time. Automatic gain control circuitry in the receiver controls the magnitude of the equivalent time sample signal. A signal processor analyzes the sample signal to indicate the time-of-flight of the electromagnetic pulses in the sequence.

The abstract of U.S. Pat. No. 5,982,352 for a method for providing human input to a computer by Timothy R. Pryor, patented Nov. 9, 1999, provides the following description, “The invention provides a method for providing human input to a computer which allows a user to interact with a display connected to the computer. The method includes the steps of placing a first target on a first portion of the user's body, using an electro-optical sensing means, sensing data related to the location of the first target and data related to the location of a second portion of the user's body, the first and second portions of the user's body being movable relative to each other, providing an output of the electro-optical sensing means to the input of the computer, determining the location of the first target and the location of the second portion of the user's body, and varying the output of the computer to the display based upon the determined locations for contemporaneous viewing by the user.”
