A coordinate measuring apparatus and a method of controlling the same are provided. The coordinate measuring apparatus includes a touch panel including a plurality of electrodes, a driver configured to generate a driving signal and to provide the driving signal to the touch panel, a receiver configured to receive a first receiving signal for detecting a change in capacitance from the touch panel and a second receiving signal corresponding to a signal transmitted from a coordinate indicating apparatus, and a processor configured to determine an activation region from which a hand position is detected, based on the second receiving signal, and determine the hand position in the determined activation region.
