  • the video system can transmit a load control signal to the exercise machine so as to vary load resistance in accordance with the outcome of the video game. In this manner, the user receives not only visual feedback via the television or other display, but also receives feedback in the form of changing load resistance.
  • Another object of the invention is to provide a protocol for establishing communication between an exercise machine and a video system.
  • the protocol can be practiced with the hardware configuration described above, or other suitable variations.
  • the exercise machine and video system are connected for two-way communication by, for example, the above-described interface module.

  • the user can select the desired mode of operation. Additional modes are possible. In multi-player video games, it is also possible for the first player to operate the game using an exercise machine in interactive exercise mode, while a second player also operates the game using conventional game controls in a stand-alone mode. In this mode two players, only one of whom is using the exercise machine, can compete with each other in the same video game. Similarly, it is possible to have two exercise machines connected to the video system so that the players can compete in a video game using the exercise machine.

In this manner, changes in actual imposed load occur concurrently with changes in video display or other program results.
  • the video system is a cartridge-type video game system.
  • the game system is interfaced with an exercise machine so that the user's exercise performance affects game play, and the game play affects the load resistance imposed on the user by the exercise machine.
  • the game includes an animated display of a race over terrain of varying grade and quality.

By taking load response into account, the changes in load resistance more realistically correspond to the program results.
  • the exercise machine uses an alternator having a nearly instantaneous response to changes in the load control signal
  • the video system will vary the load control signal simultaneously with variations in the depicted terrain.
  • the exercise machine uses a band or eddy current brake having a delayed response to changes in the load control signal
  • the video system will change the load control signal prior to the displayed variations in the terrain. In this manner, the user does not experience discontinuity between the depiction of terrain variations and the imposition of load resistance.
  • the exercise machine communicates its operating characteristics to the video system. This can be accomplished in accordance with the above-described or other communications protocols.
  • the video system can transmit desired current and future load values to the exercise machine. The exercise machine can then adjust the load control signal to achieve the desired future load resistances in accordance with its particular operating characteristics.
