ABSTRACT:
The present invention provides an information input/output device for visually impaired users whereby the visually impaired users can easily obtain information for the operation and perform the operation without confusion. This device comprise a braille output unit having a plurality of projectable dotted portions and which enables output of a plurality of braille patterns by controlling the projection of the dotted portions, and a recognition means which recognizes that an operation concerning the braille patterns output by the braille output unit is input when the braille output unit is pushed within a predetermined period of time after the braille patterns are output by the braille output unit. When the user inputs an operation concerning the braille patterns, the user pushes the braille unit in which the braille patterns are output.
