Abstract: An electronic chess set includes a plurality of conductive chess pieces, a chessboard having a playing surface including a plurality of individually identifiable locations visible to a user on the chessboard, and an electronic system including a capacitive sensing system. In some embodiments, the capacitive sensing system is configured to determine for each of the plurality of individually identifiable locations: when a chess piece included in the plurality of conductive chess pieces is located at a respective one of the plurality of individually identifiable locations and user-contact with the chess piece is absent; when the chess piece located at the respective one of the plurality of individually identifiable locations is in contact with the user; and when each of the plurality of conductive chess pieces is absent from the respective one of the plurality of individually identifiable locations.
