Development of an Exergame for individual rehabilitation of patients with cardiovascular diseases

An Exergame prototype for improved and patient-adapted rehabilitation was developed. A target heart rate for individual users was defined and tracked using a chest belt. Physical activity was tracked by two 3-axis accelerometers, fixed to both wrists. Dependent on the recorded heart rate and by means of a supporting factor and linear regression the movement of the user within the game was supported or hindered. The Exergame was evaluated on 15 healthy users regarding entertaining aspects, physical effort, and impressions concerning the handling of the whole setup. The support factor algorithm to reach the target heart rate was reliable in all subjects.
