Gait Analysis System by Augmented Reality

Gait analysis is the systemic study of human walking. In this paper we present the development of a 3D gait analysis system based on Augmented Reality (AR). AR allows a user to see a real world with virtual elements overlapped upon it in real time. To build the 3D Gait Analysis system was necessary to determine markers position for gait analysis, develop an electronic circuit with Arduino technology to control accelerometers and infrared leds to feed the virtual 3D scene, develop human-machine interface to establish a communication protocol between the electronic circuit and the computer and generate augmented reality based on accelerometers and infrared leds.
