Abstract: An activity controlled audio-visual system is disclosed. A device for connecting exercise equipment such as a pedal exerciser to a user sensory interface, such as a television set or computer so that the user has to pedal at a rate above a preset rate or threshold rate in order to be able to view the user sensory interface signal. The act of pedaling above a preset rate turns on a switch box which controls the input to the user sensory interface. In this way a normally sedentary activity such as watching television or a video, playing a video game, or using a computer is converted to one that requires physical activity.
