WIDEBAND TRANSMITTER FOR POSITION TRACKING SYSTEM IN COMBINED VIRTUAL AND PHYSICAL ENVIRONMENT
First Claim
1. A method for transmitting a plurality of wide band tracking signals within a position tracking system, the method comprising:
- serially transmitting portions of a transmitter identifier for each transmitter by each transmitter of a plurality of transmitters in serial format, the transmitters located within a pod, the pod including one or wide band receivers;
transmitting a wide band pulse from the first transmitter of the plurality of transmitters; and
transmitting a wide band pulse from each of the remaining plurality of transmitters; and

Abstract
A positional tracking system used in a virtual reality environment in which multiple users may freely and unrestrictedly explore an environment without affecting position tracking. Receivers mounted to the user in several locations may be accurately tracked regardless of the position of the user and other users in the system. A plurality of transmitters may transmit wide band signals to one or more receivers on a user. Each receiver may receive the wide band signals from the plurality of transmitters, process those signals, and determine a receiver location based on the received signals. The signals themselves may be wide band signals, for example in the range of 3 GHz to 10 GHz. The wide band signals may include identifier information and a pulse for determining a time-of-flight between the transmitter and receiver.

23. A system for transmitting a plurality of wide band tracking signals within a position tracking system, the system comprising:
-
a plurality of transmitters, each transmitter including an antenna and circuitry; the antenna for each transmitter configured to transmit a wideband signal; the circuitry serially transmitting portions of a transmitter identifier for each transmitter through the antenna as a wideband signal, the transmitters located within a pod, the pod including one or wide band receivers; the circuitry generating a wide band pulse and transmitting the wide-band pulse serially through an antenna of each transmitter; the circuitry repeating the serial transmission of the wideband pulses from each of the plurality of transmitters until a minimum number of transmissions required for sub-sampling processing by a receiver have been sent by each transmitter. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32)
