<p>Disclosed herein is a computer for the blind. The computer includes a display lattice part, an auxiliary button part, a coordinate conversion unit, and a voice output unit. The display lattice part is located on a touch panel that generates coordinate signals corresponding to a point touched by a user, and is configured such that quadrangle lattice cells having a predetermined arrangement are formed, and buttons on which sequentially increasing Braille numbers are marked are arranged in the respective lattice cells. The auxiliary button part includes buttons for moving a cell cursor for performing a current task to an upward, downward, leftward or rightward lattice cell of the lattice cells, and an enter key button for allowing the user to select a lattice cell for the cell cursor. The coordinate conversion unit converts a lattice cell, which contains a touched point, into the cell cursor when the user touches the touch panel. The voice output unit outputs the menu of a program or content of an information corresponding to a changed location in voice form when the location of the cell cursor is changed.</p> |
