  • Patent number: 6517438
    Abstract: A game processing device processes a simulated game wherein an input device is modeled on an instrument required for a prescribed action in real life. This game processing device comprises game developing means for developing a game simulating said real-life action and providing a display indicating that said instrument has received an impact at a timing during said game corresponding to a time when said instrument would receive an impact during said real-life action; and instruction means for outputting an instruction signal to said input device indicating that said impact has been received at a timing during said game corresponding to a time when said impact would be received. When movement information indicating the movement of said input device and supplied by said input device reaches prescribed conditions, the development of the game by said game developing means is changed.

  • Patent number: 6312335
    Abstract: An input device in which a player moves the whole of the input device and a game processing device for processing a simulated game are disclosed. The input device is modeled on an instrument required for a prescribed action in real-life. The input device includes detecting means for detecting physical quantities corresponding to the movement of the input device as a whole and converting the physical quantities to a detection signal which is output. The input device further includes vibration transmitting means, fixed to the casing of the input device so that vibration is transmitted to the input device, for inducing mechanical displacement corresponding to prescribed instruction signals. The game processing device includes game developing means for developing a game simulating the real-life action and for providing a display indicating that the instrument has received an impact at a time during the game corresponding to a time when the instrument would receive an impact during the real-life action.
