Abstract

Abstract: Refreshable braille display is an important application of haptic rendering in virtual reality.Aprototype of a layered electro-magnetic refreshablebraille displaywas developed, which has complex mechanical structures and a control system, and coulddynamical display of20braille words. By designing the layered and dislocatedbraille driving mechanism, this refreshablebraille displayrealizedthe arrangement of 120 braille points. By switchingthe current of the electromagnetic coils, the control system of this refreshablebraille displayrealizedthe movement control of these braille points. This prototype has the advantages of small volume, low cost, high refresh rate, and can generate enough supporting forcefor fingertip haptic reading braille.
