For ease of reading by blind people, braille typewriters and printers have been developed. Most graphic devices have been designed to produce lines or printed areas. There are advantages, however, to embossed lines or textured computer output which may make it useful to have computer graphic textured or tactile output. The only previous tactile output produced has been for blind reading, or for lines embossed on heavy paper.
