Abstract
Abstract A system is provided for monitoring the physiological exertion of a user. One or more sensors are attached to the limbs of the user to measure the user's motion. The sensors can measure either the acceleration or the force on the limbs. The measured signal is transmitted to a monitor by a wireless transmitter, such as an infrared, acoustic or radio transmitter. The monitor determines and displays the level of physiological exertion of the user by a mathematical formula or a look up table based on the measured motion of the user. The system can also measure and display various other physiological parameters of the user, such as pulse rate, blood pressure, etc. The system includes an interactive video display with a branching video sequence. The rate of progress and the direction of the video sequence at each of the branching points are interactively controlled by the level of physiological exertion and the movements of the user. The system can also record and display the level of physiological exertion and other physiological parameters of the user over time to create a personal exercise log.
