Tennis game system
First Claim
1. A tennis game system including a game machine and a racket-shaped input device imitating a form of a tennis racket, under which a player plays a tennis game using said racket-shaped input device, wherein said racket-shaped input device comprises an acceleration sensor for generating an acceleration correlation signal when said player actually swings said racket-shaped input device in a real space, and a transmission means for transmitting generated said acceleration correlation signal to said game machine;
- and said game machine displays a ball on a monitor screen through execution of a tennis game program in which a CPU player controlled by a computer program plays a match against said player, and further comprises;
a first calculation means for calculating a Predicted return position of said ball returned by said CPU player;
a judgment means for judging whether a current position of said player is in a ball strikable range by comparing said predicted return position and the current position of said player;
a ball striking position movement means for moving a ball striking position of said player in response to a negative judgment by said judgment means;
a swing detection means for detecting whether said racket-shaped input device has been actually swung or not; and
a second calculation means for calculating an initial speed vector of said ball after received when said swing detection means has detected a swing in said ball strikable range, from a position of said ball and acceleration of said racket-shaped input device according to said acceleration correlation signal.

Abstract
A tennis game system includes a game machine connected to a television set via an AV cable, and a racket-shaped input device for inputting operation to the game machine. A game player instructs a ball striking player to strike a ball on a monitor screen by operating the racket-shaped input device. At this time, a game processor included in the game machine calculates a predicted return position of a ball returned by the opposite player, compares a current position of the ball striking player with the predicted return position, and judges whether the predicted return position is within a ball strikable range for the ball striking player. If a judgment means judges that the predicted return position is out of the ball strikable range, a ball striking position movement means, i.e. the game processor moves the ball striking position.

6. A tennis game system including a game machine and two racket-shaped input devices imitating the form of a tennis racket, under which two players play a tennis game using said racket-shaped input devices, wherein
said racket-shaped input devices each comprise an acceleration sensor for generating an acceleration correlation signal when said player actually swings said racket-shaped input device in a real space, and a transmission means for transmitting generated said acceleration correlation signal to said game machine; -
said game machine runs a tennis game program in which said two players play a match and displays said ball on a monitor screen, and further comprises;
a first calculation means for calculating a predicted return position of a ball returned by an opposite player;
a judgment means for judging whether a ball striking player is in a ball strikable range by comparing said predicted return position and a current position of said ball striking player;
a ball striking position movement means for moving a ball striking position for said ball striking player response to a negative judgment by said judgment means;
a swing detection means for detecting whether said racket-shaped input device has been actually swung or not; and
a second calculation means for calculating an initial speed vector of said ball after received when said swing detection means has detected a swing in said ball striking-enabled range, from a position of said ball and acceleration of said racket-shaped input device according to said acceleration correlation signal.
