Game device, game control method, information recording medium, and program

A method for controlling a game executed by a measurement unit, an extraction unit, and a determination unit included in 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 method includes:

• a measuring step that a measurement unit measures acceleration of the controller over a predetermined time zone associated with each predetermined target point;
• an extracting step that an extraction unit 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 determining step that a determination unit 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 target point in time, and determines a score based on the difference between each target point in time and the associated selected time point.

A non-transitory computer-readable information recording medium stored a program to execute a game determining accuracy of user's operation of a controller depending on whether a user moves a controller at a predetermined target point in time, the program causes a computer that the controller is connected to function as:

• 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.
