Tâche d'évitement d'obstacles par un participant au sein de la rue artificielle Streetlab
Obstacle avoidance task being performed by a participant on the Streetlab artificial street, a platform for improving the mobility of visually impaired people. He is fitted with reflective markers placed on anatomical landmarks for motion capture. The position of the markers is determined by triangulation using a network of infrared cameras. This enables precise measurement of the patient's movements and analysis of his motor behaviour (gait cycle, speed, coordination, etc.). The direction of his gaze is also obtained at each stage by means of an eye tracker, which constantly analyses eye movement. All of the strategies that the patient employs to move about and to avoid obstacles are analysed.
