Game device and game system
View Patent ↗A technique which easily removes the motion element of a game controller which is attributed to the vibrating motion of a vibrator from the output data of an acceleration sensor or reduces the element is provided. In a game device, a wireless communication module receives an acceleration sensor output data, which has been analog-to-digital converted, in a game controller. A sensor output correction unit corrects the received acceleration sensor output data and provides the corrected acceleration sensor output data to the application processor. In the sensor output correction unit, a masking processing unit performs the masking process on the acceleration sensor output data within the predetermined range of masking. The masking processing unit corrects the acceleration sensor output data within the range of masking including zero acceleration to have zero acceleration.
