Game controller with pulse width modulation position detection

摘要

A game controller includes a plurality of LEDs formed on the rear of a case. The plurality of LEDs are arranged two-dimensionally in its layout area. The game controller has a plurality of PWM control units which are provided inside the case and control the lighting of the plurality of LEDs, respectively. The PWM control units control the lighting of the LEDs based on a control signal from a game apparatus. The game apparatus acquires a captured image of the game controller, and acquires the position of the game controller in the captured image based on the positions of the LEDs in the captured image.

1. A game controller capable of communication with a game apparatus, the game apparatus including an imaging device, the game controller comprising:
a wireless communication module configured to transmit a user's operation inputs to the game apparatus input via a plurality of input units provided on a top or rear of a case; a light-emitting element provided on the rear of the case; and a processing unit configured to cause the light-emitting element to emit light so as to allow the user to identify the game controller, wherein the processing unit includes a PWM control unit that operates to light the light-emitting element, wherein the light-emitting element caused by the processing unit to emit light is imaged by the imaging device and used by the imaging device to detect a position of the game controller.
