Input/output tactile feel device
Abstract
A Braille device (16) includes a plurality of Braille cells (18-22) that comprise a plurality of pins (24-26) that are actively positioned to present information to a user via tactile feel. The Braille device also allows the user to depress at one or more of the pins in order to make a selection analogous to point and click of a mouse. To allow the user to move a screen cursor and make selections via the Braille pins, the Braille cell includes pin position sensing circuitry (28-30) that senses the position of each of the plurality of Braille pins. A system controller (e.g., a CPU) reads the information from the sensing circuitry to determine which pins, if any have been depressed. Advantageously, the Braille pins are used as an output device that allows a user to read information, and also as an input device by allowing the user to depress the Braille pins in order to make a selection.
