SWITCHABLE CONVERSION OF A STANDARD KEYBOARD TO A BRAILLE INTERFACE

Abstract

Keyboards that are selectably configurable between a standard interface and a braille interface. In embodiments, the keyboard is equipped with six keys corresponding to six dots of a braille matrix, each of the keys equipped with a shape memory alloy spring or other mechanism to cause each of the keys to selectably extend above the keyboard plane. On activation, the six keys are extended and the remaining keys deactivated, to provide an easy to locate braille interface. On subsequent activation, the six keys are retracted and the keyboard is reverted to a standard interface. Other embodiments may be described and/or claimed.
