A Kinect-Based Augmented Reality Game for Lower Limb Exercise

Abstract

Augmented reality (AR) is where 3D virtual objects are integrated into a 3D real environment in real time. The augmented reality applications such as medical visualization, maintenance and repair, robot path planning, entertainment, military aircraft navigation, and targeting applications have been proposed. This paper introduces the development of an augmented reality game which allows the user to carry out lower limb exercise using a natural user interface based on Microsoft Kinect. The system has been designed as an augmented game where users can see themselves in a world augmented with virtual objects generated by computer graphics. The player sitting in a chair just has to step on a mole that appears and disappears by moving upward and downward randomly. It encourages the activities of a large number of lower limb muscles which will help prevent falls. It is also suitable for rehabilitation.
