(US5462503-A)      An exercise apparatus comprising:    a support structure for supporting a user;    an exercise mechanism for providing exercise to the user supported by the support structure;    a steering mechanism proximal to the support structure;    a processor for generating an interactive simulated environment and monitoring user manipulation of the exercise mechanism and the steering mechanism to determine user position in the simulated environment; and    a display system spaced from the user and providing a visual display of the simulated environment and user position in the simulated environment;    the processor being configured to enable the user to (i) travel substantially unrestricted throughout the simulated environment by manipulating the exercise mechanism and the steering mechanism, (ii) spontaneously modify user's course while travelling within the simulated environment, and (iii) participate in user selectable activities within the simulated environment.    (JP8510655-W)      The excercise appts. (22) enables a seated (25) user to exercise has a support structure (24,26) supporting the user and an excercise mechanism. A steering/tilting mechanism (30), enables freedom of navigation through a simulated environment. A computer (32) generates a desired environment which is displayed (35) to the user. The computer monitors the user's physical activity to determine the user's position in the simulated environment. Fan (38) simulates wind-blowing.    Preferably, several interactive exercise appts. may be networked together to allow group participation, thus enabling team-games and races to be held. Simulated environments may be of multi-dimensional nature to increase realism. Aerobic exercise by foot-pedalling (27) may be electronically controlled with a digital closed loop.    USE/ADVANTAGE -   Makes workout more enjoyable. Enables team-games and races to be held in simulated environments, e.g. cross-country running.    (EP682544-B1)      The excercise appts.
