Abstract:
1. A game device determining accuracy of user's operation of a controller depending on whether a user moves a controller at a plurality of predetermined target points in time, the game device comprising: a measurement unit that measures acceleration of the controller over a predetermined time zone associated with each predetermined target point; an extraction unit that compares the measured acceleration of the controller, during the predetermined time zone associated with each target point, with a first threshold, and responsively stores an associated time point when the measured acceleration crosses the first threshold by an increasing acceleration and by a decreasing acceleration; and a determination unit that establishes, for each predetermined time zone, a selected time point, from the stored associated time points for the predetermined time zone, which is closest to the predetermined target point in time, and determines a score based on a difference between each target point in time and the associated selected time point.
