A device for operating 3D virtual chessboard, the device is used for a tablet PC provided with at least two cameras and one micro 3D holograph projector, the at least two cameras are used to capture images of chess games, and the micro 3D holograph projector is used to map the chessboard displayed on the tablet PC into 3D space, wherein the device includes:

• an image identifying module which identifies images captured by the at least two cameras;
• a start action determining module which determines the start of an action for chess games based on the image identification result of the image identifying module, so as to determine which chess piece is moved;
• an end action determining module which determines the end of the action for chess games based on the image identification result of the image identifying module, so as to determine the final location to which the chess piece is moved;
• an effective location determining module which determines whether the final location to which the chess piece is moved is an effective location based on a rule of chess games;
• a mapping module which maps the final location into a coordinate location of the chess piece on the tablet PC, if the effective location determining module determines that the final location to which the chess piece is moved is the effective location;
• a chessboard updating module which updates the chessboard displayed on the tablet PC based on the coordinate location of the chess piece on the tablet PC.
