Abstract
This disclosure is directed to a system to compensate for visual impairment. The system may comprise, for example, a frame wearable by a user to which is mounted at least sensing circuitry and display circuitry. The sensing circuitry may sense at least visible data and depth data. Control circuitry may then cause the display circuitry to visibly present the depth to the user based on the visible data and depth data. For example, the display circuitry may present visible indicia indicating depth to appear superimposed on the field of view to indicate different depths in the field of view, or may alter the appearance of objects in the field of view based on the depth of each object. The system may also be capable of sensing a particular trigger event, and in response may initiate sensing and presentation for a peripheral field of view of the user.
