Game system, game apparatus, storage medium having game program stored thereon, operation determination method, and information processing apparatus

A game apparatus configured to execute a game process in connection with at least one physical, handheld operation device, the game apparatus including a computer configured to:

• calculate an attitude of the at least one operation device;
• provided that the attitude is included in a first range at a timing when an instruction operation is made using the at least one operation device, make a success determination that the instruction operation is successful;
• make the success determination that the instruction operation is successful even though the attitude is included in a second range outside the first range at the timing the instruction operation is made, provided that, within a predetermined time period after the timing, (a) the attitude is included in the first range or a third range including at least a part of the first range, and (b) the at least one operation device is put into a still state or the at least one operation device moves by no more than a predetermined amount;
• and
• execute the game process based on a result of the success determination,
• wherein the at least one operation device includes a gyrosensor configured to detect an angular velocity from which the attitude of the at least one operation device is calculated and/or an acceleration sensor configured to detect an acceleration from which the attitude of the at least one operation device is calculated.

A non-transitory computer-readable storage medium having stored thereon a game program executable by a computer included in a game apparatus, the game program causing the computer to execute functionality comprising:

• calculating an attitude of at least one physical, handheld operation device;
• provided that the attitude is included in a first range at a timing when an instruction operation using the at least one operation device, making a success determination that the instruction operation is successful;
• making the success determination that the instruction operation is successful even though the attitude is included in a second range outside the first range at the timing the instruction operation is made, provided that, within a predetermined time period after the timing, (a) the attitude is included in the first range or a third range including at least a part of the first range, and (b) the at least one operation device is put into a still state or the at least one operation device moves by no more than a predetermined amount;
• and
• executing a game process based on a result of the success determination,
• wherein the at least one operation device includes a gyrosensor configured to detect an angular velocity from which the attitude of the at least one operation device is calculated and/or an acceleration sensor configured to detect an acceleration from which the attitude of the at least one operation device is calculated.

An operation determination method for use with at least one physical, handheld operation device, the operation determination method comprising:

• calculating an attitude of the at least one operation device;
• provided that the attitude is included in a first range at a timing when an instruction operation is made using the at least one operation device, making a success determination that the instruction operation is successful;
• and
• making the success determination that the instruction operation is successful even though the attitude is included in a second range outside the first range at the timing the instruction operation is made, provided that, within a predetermined time period after the timing, (a) the attitude is included in the first range or a third range including at least a part of the first range, and (b) the at least one operation device is put into a still state or the at least one operation device moves by no more than a predetermined amount,
• wherein the at least one operation device includes a gyrosensor configured to detect an angular velocity from which the attitude of the at least one operation device is calculated and/or an acceleration sensor configured to detect an acceleration from which the attitude of the at least one operation device is calculated.

An information processing apparatus configured to perform an information process in connection with at least one physical, handheld operation device, the information processing apparatus comprising a computer configured to:

• calculate a parameter controllable by moving the at least one operation device;
• provided that the parameter is included in a first range at a timing when an instruction operation is made using the at least one operation device, execute the information process based on the first range;
• and
• execute the information process based on the first range, even though the parameter is included in a second range outside the first range at the timing the instruction operation is made, provided that, within a predetermined time period after the timing, (a) the parameter is included in the first range or a third range including at least a part of the first range, and (b) the at least one operation device is put into a still state or the at least one operation device moves by no more than a predetermined amount,
• wherein the at least one operation device includes a gyrosensor configured to detect an angular velocity from which the parameter is calculated and/or an acceleration sensor configured to detect an acceleration from which the parameter is calculated.
