I designed a very convenient interface for my otherwise extremely simple Chess program. In most chess games, keyboard interface works like this: one axis has labels 1, 2, 3, 4, 5, 6, 7, 8; the other has a, b, c, d, e, f, g, h. Then you movie pieces by inputing stuff like b4 d5. This is AWFUL. You have to look at the border of of the chessboard to see which row and column your chess piece is in. It wasn't designed for humans to play, it was for keeping records of matches and tournaments. My interface works differently: each of your pieces having valid moves is assigned a key on keyboard. For example rooks could be labeled 1-8, others a-h. You select a piece to move simply by inputing its symbol. When that happens, spaces reachable with legal moves become labeled with symbols... You see where that goes. You look at a piece you want to move, read its symbol, then read the symbol of the place you want to move to. In each case you look at pieces or spaces that interest you, not at X and Y axis.
