Abstract

The game apparatus (1) has a fixed main unit (100) and a movable operating device (8) that is held by a player and is capable of detecting the body motion of the player and of transmitting a signal to, receiving from, the main unit (100). The operating device (8) has an acceleration sensor (86) for detecting acceleration, a light source (85), and a transmitter (87) for transmitting a value detected by the acceleration sensor (86) to the main unit (100). The main unit (100) has light receiving units (9L,9R) that receive the light emitted from the light source (85) to detect the intensity of the received light, a RAM (14), and a processor (16). Processor (16) repeats a process of detecting the position of the operating device (8) based on the intensity of light detected by each of the light receiving units (9L,9R), causes a RAM (14) to store the detected position history, determines whether a player has performed a predetermined motion based on the position history and the detected value of the acceleration sensor (86).

Claims

a fixed main unit; and

a movable operating device, held by an operator, that detects body motions of the operator and for transmitting signals to, and receiving from, the main unit,

the operating device comprising;

an acceleration sensor that detects acceleration;

a light emitter that emits light; and

a transmitter that transmits a value detected by the acceleration sensor to the main unit, and

the main unit comprising;

light receivers arranged at least at two positions, each receiving light emitted from the light emitter and detecting an intensity of the received light;

a position detector configured to detect a position of the operating device based on the intensity of the received light detected by each of the light receivers;

a storage device configured to store history of each position of the operating device detected by the position detector; and

a motion determiner configured to determine whether the operator has performed a predetermined motion on the basis of the history of the positions of the operating device and the detected value of the acceleration sensor,

wherein the game executor is further configured to execute a predetermined instruction in a case in which it is determined by the motion determiner that a predetermined motion has been performed,

wherein the motion determiner is further configured to determine whether an extension and retraction motion of the operator has been performed based on the relationship between a first determination distance of a first position detected by the position detector and a second determination distance of a second position previously detected immediately before the detection of the first position detected by the position detector, the first and the second determination distances being a distance between an origin and a position detected by the position detector after the origin was detected, with the origin being a point of a position detected by the position detector immediately before acceleration of equal to or greater than a predetermined standard value is detected by the acceleration sensor.

2. A game apparatus according to claim 1, further comprising:

a type identifier that, in a case in which it is determined that an extension and retraction motion of the operator has been performed, identifies a type of the extension and retraction motion of the operator based on the history of each position of the operating device.

3. A game apparatus according to claim 2,

wherein the type identifier identifies the type of the extension and retraction motion of the operator based on a direction of the extension and retraction motion and a predetermined range of the direction, the direction being assumed as corresponding to a direction of a straight line passing through a destination point and the origin, with the destination point being the position that is the most distant from the origin.

4. A game apparatus according to claim 1,

wherein the motion determination apparatus further comprises a direction calculator that calculates a direction of a straight line passing through the origin and the second position in a case in which the motion determiner determines that an extension and retraction motion of the operator has been performed.

5. A game apparatus according to claim 1,

6. A game apparatus according to claim 1,

wherein the frequency of light emitted by the light emitter is set to a frequency that does not interfere with external light.

7. A game apparatus according to claim 1, wherein

the operating device is held by or is worn on a hand of the operator, and

the motion determiner is further configured to determine that the extension and retraction motion is a hitting motion.

the motion determiner is further configured to determine that the extension and retraction motion is a bending and stretching motion.

10. A game apparatus comprising:

a motion determination apparatus;

a display unit connected to the main unit; and

a game executor that is provided with the main unit and is configured to conduct a game by using the display unit,
