  • METHOD AND SYSTEM FOR DETECTING SPATIAL POSITION OF INDICATOR OBJECT BY USING SOUND WAVE
    Publication number: 20140050052
    Abstract: A method for detecting a spatial position of an indicator object by using sound waves. The method is adapted to be used with a sound wave transceiver device and a plurality of sound wave receiving devices. The method includes steps of: obtaining a relative position of the sound wave transceiver device to each one of the sound wave receiving devices; obtaining a plurality of reflection times respectively indicating time periods from the sound wave transceiver device emitting the sound wave to the sound wave transceiver device and the sound wave receiving devices receiving the reflected sound wave from the indicator object; and calculating a position of the indicator object according to the relative positions and the reflection times. A system for detecting a spatial position of an indicator object by using sound waves is also provided.
