Abstract

A system is provided including a tactile assembly having a plurality of solenoid units adapted to transfer to an extended orientation upon the actuation thereof. Also included is a camera unit for generating an image indicative of a present perspective of objects situated in a predetermined direction. Next provided is control circuitry for actuating the solenoid units to simulate the image generated by the camera unit such that the solenoid units actuated are those which correspond to pixels within the image that have either a higher or lower brightness.
