    摘要: In an interactive display system, a transmitter is provided for transmitting a periodic signal to a plurality of receivers through the air. One or more phase differences are measured between the receiving at pairs of receivers. These phase differences control the coordinates of a locator on a display screen. Separate measured phase differences control the positions along different coordinate axes independently.
