发明名称 Chess set for the blind
摘要 A chess set for blind players. The board includes squares having different tactile patterning to distinguish different colors. Each square contains a hole extending through the board. A border includes indicia, both visual and tactile, to indicate the file and rank. The bottom of the board includes the holes which extend from the top. The holes are connected with lines which can be felt connecting the holes in the horizontal, vertical and diagonal directions. The pieces include projections which extend through the holes and which have some indication of both the color and type of piece so that a blind player can feel possible moves on the bottom of the board by the various pieces.
