| Title: |
Tracking System |
| Abstract: |
A performer tracking system, and an associated method, for tracking
movements of at least one performer upon a stage. A plurality of signal
transmitters are positioned about the stage and transmit electromagnetic
signals. Performers on the stage carry transponders which receive the
electromagnetic signals and, responsive thereto, generate coded sound
signals. Sound signal receivers positioned together with the signal
transmitters receive the sound signals. A controller determines positions
of the transponders and, hence, the performers carrying the transponders
and causes spotlights to track the performers.
