Abstract

A memory card with a tilt sensor is inserted into a personal digital assistant (PDA). When the PDA is tilted back and forth, the tilt sensor detects a tilt angle and outputs the tilt angle to an A/D converter. The A/D converter converts the tilt angle into digital data and supplies the digital data to a signal controller. The signal controller converts the format of the tilt data (digital data) into a communication format processable by the PDA in which the memory card is installed. The signal controller outputs the converted data to the PDA through an input/output interface. Accordingly, the PDA can control display of a game screen in accordance with the tilt data supplied from the memory card. A user who used to play the game using key input can now cause the PDA to function as a more interesting game machine.
