Title:
METHOD AND SYSTEM FOR OBTAINING POSITIONING DATA
Document Type and Number:
WIPO Patent Application WO2003088136
Kind Code:
A3
Abstract:
A position detection system for use in association with computing applications, the system comprising: a positional element for attaining a position and comprising a first emitter for emitting a substantially continuous ultrasonic waveform decodable to fix said position, and a detector arrangement for detecting said waveform in a manner permitting fixing of said position and outputting said waveform for computation, in a manner retentive of said position fixing ability.
