Abstract
A technique which easily removes the motion element of the game controller which is attributed to the vibrating motion of a vibrator from the output data of an acceleration sensor or reduces the element can be achieved by the present invention. In a game controller, an acceleration sensor detects the movement of the game controller. LPF is installed at the output of the acceleration sensor. Vibrators are installed inside of a housing. The cutoff frequency of LPF is set lower than the peak value of the natural frequency of the game controller. The cutoff frequency of LPF may be set to two thirds or less of the peak value of the natural frequency of the game controller.
Claims9
A game controller operative to transmit game operation data to a game device, comprising:
- a housing;
- a motion sensor operative to detect a movement of the game controller;
- a low pass filter installed at an output of the motion sensor;
- and
- at least one vibrator which is driven by a vibration controlling signal sent from the game device,
- wherein the motion sensor, the low pass filter and the at least one vibrator are placed inside the housing, the at least one vibrator being fixed to the housing,
- a cutoff frequency of the low pass filter is set lower than a natural vibration frequency of the game controller, wherein the cutoff frequency of the low pass filter is set so that at least a part of a vibration component of the housing attributed to a vibrating motion of the vibrator can be removed, while the movement of the controller caused by a movement of a user can be output from the low pass filter, and
- wherein the cutoff frequency of the low pass filter is set with reference to a duration of transmission cycle of game operation data.
