摘要

Ergonomic Braille output unit comprises a Braille module with a touch or key surface (2) that has a 2 x 4 hole matrix in which a total of 8 touch or key pins are inserted. The key surface is concave and slopes backwards so that tactile Braille reading can be carried out with a natural unstrained attitude of the sensing finger (4) and the reading hand.
