Exercising system with electronic inertial game playing

Abstract

An exercise and game playing system combined, forming a method in which the user gets large muscle physical exercise while at the same time is challenged with game play. There is a torso and limb mounted electronic section incorporating accelerometers, strain gauges, and other instruments, and a microprocessor, and a short range radio or wire link to a stationary base station and a display station. Body activity and exercise produce a display icon responsive to the degree and vigor of body activity. The display is a TV type screen or a head band mounted assembly or goggles of a virtual reality system. The accelerometer signals are double integrated and manipulated to produce useful display on the screen. There is net cursor advancement activity on the screen even when the body returns to the same location, accomplished by introduction of a dead zone in the accelerometer integration paths. A score is kept of how well the user follows the game commands, such as staying within the boundaries of a screen track, or avoiding collision with game obstacles. There are special effects for games, such as triggering the imaginary throw of a javelin or discus, or firing imaginary weapons or setting up a military defense, or imaginary enemies. The display effects are proportional to the vigor of the exercise, and are also proportional to the product of acceleration and applied muscle tension. There is a music source and sounds responsive to exercise effort, and a voice report of the status of the exercise regime and the value of effort achieved. Other elements include: handles for applying force to strain gauges; heart beat sensors, nerve activity and muscle sensors, buttons, and switches.
