An isometric exercise system according to the present invention facilitates user interaction with a host computer system and includes at least one effector, at least one sensor coupled to the effector, a platform to accommodate the user and control circuitry including a processor. The platform accommodates a user and includes the effector attached thereto. The sensor measures at least one force applied by a user to the effector, where the applied force effects a strain on or deflects the effector. The processor receives and processes data corresponding to applied force information measured by the sensor for transference to the host computer system in a compatible format and facilitates user interaction with the host computer system via effector manipulation by the user. The host computer system processes the information to update or respond to events within an executing software application (e.g., a game).
