Abstract: A position detection apparatus and method are provided. The apparatus includes a touchscreen on which an image is displayed, a sensor, and a controller. The sensor includes at least one hall element. The method includes detecting a touch coordinate input into a touch panel through the touchscreen, storing the detected touch coordinate, counting a number of detected touch positions to determine whether a an executing application program permits only a single touch input, and selectively operating the sensor to detect a position of a magnet according to whether the an executing application program permits only the single touch input.
