Medical device to aid in the perception of the environment for blind or visually impaired users

摘要

The present invention relates to a device for assisting in the perception of the environment for blind or partially sighted users, comprising: - a set of mechanical actuators (3) intended to be in contact with the skin of a user, - at least a digital camera (6) arranged to acquire a current digital image of an environment facing the user, - a processing circuit (2) connected to the camera to receive pixel signals from the acquired digital image and convert a at least part of the pixel signals into control signals each supplying a mechanical actuator of the set of actuators, - an ocular tracking module (7) of each eye of the user to identify a direction of gaze of the user. processing circuit then selects in the environment filmed by the camera (6) an area of current image acquired which is a function of the viewing direction, and converts the pixel signals of this area into control signals each supplying a game actuator (3) to stimulate the user's skin.
