Abstract
Provided is a method for expressing characters, which can reduce the pain at fingertip during tactile reading, allows easier recognition than conventional Braille characters, and be substituted for the Braille characters. Another object of the present invention is to provide a print and others having the characters formed, and an apparatus for mutual conversion between the characters and regular letters or between the characters and Braille characters. The method for expressing characters for reading by tactile sense according to the present invention comprises: deciding location of multiple lines; making one or more of the lines have a raised cross section; and expressing characters by a positional pattern of the raised cross section lines. The characters have a greater contact surface with the fingertip than conventional Braille characters, and thus, reduce the fatigue and the pain at fingertip drastically during tactile reading even for an extended period of time and also reduce misreading rate to a low level.
