  • Patent number: 6452585
    Abstract: A method and apparatus is disclosed for transmitting data about an object within a defined field and using the transmitted data to generate a virtual object on the display screen of a computer. In one embodiment of the present invention the object used to transmit input data is a wireless glove assembly. The glove assembly supports a transmitting device which transmits data bursts, containing position and gesture information, in the radio frequency wavelength to four stationary receivers. The received signal is converted to a digital signal and input to a microprocessor control unit. The software used in the microprocessor control unit uses an averaging method to generate a virtual object on the computer display screen. The position of the virtual object is calculated based on the strength of the signal received. The movement of the virtual object on the computer display screen is in the same direction as and is proportional to the glove movement.
