Abstract:
A refreshable tactile reader apparatus for Braille text and graphics, utilizing a plurality of compressible tactile pins that can absorb strong downward forces. Such strong forces transmitted through tactile pins can damage pin actuation mechanisms. The physical enclosure of the reader provides open channels that allow the apparatus to be more easily cleaned than prior art enablements.
