ABSTRACT:
A Braille device includes a plurality of Braille cells that comprise a plurality of pins 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 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. In addition, depositing the electronics onto the piezoelectric bimorph reduces the overall size of the Braille device.
