Abstract
A digitizer system includes a stylus comprising a plurality of transmitters for transmitting signals, wherein each of the plurality of transmitters are distanced from one another by a defined distance, a digitizer sensor operable for sensing signals transmitted by the plurality of transmitters, and circuitry associated with the digitizer sensor for tracking a projected location on the digitizer sensor of each of the plurality of transmitters based on the signals sensed, and for tracking a geometric relationship between the projected locations.
