64 (the number of squares on a chessboard) is only 2 to the 6th power. You could give two buzzers (one per hand or leg or wherever) and signal the target square quite easily: 100101 =37, which indicates e5. (If multiple pieces could move there, the transmitter could indicate the square on which the desired piece sits before moving.)
