Coordinate measuring apparatus and coordinate measuring system having the same

摘要

A coordinate measuring apparatus and a coordinate measuring system are provided. The coordinate measuring apparatus includes a channel electrode circuit including a plurality of electrodes, a driver configured to generate a driving circuit signal and provide the driving signal to the channel electrode circuit, a receiver configured to receive first receiving signal for detecting capacitance change from a portion of the plurality of electrodes, and simultaneously receive second receiving signal corresponding to a signal transmitted from a coordinate indicating apparatus from another portion of the plurality of electrodes, and a processor configured to determine a position of at least one of a hand and the coordinating indicating apparatus based on the received first receiving signal and second receiving signal.
