Natural User Interface for Board Games Using Lenticular Display and Leap Motion
Various board games, including chess, are now played on PCs, but they differ from actual board games because a mouse is typically used to move the pieces. Moving a piece by pinching it with one’s fingers, as in actual board games, is desirable to increase a player’s sense of reality. That the pieces look as if they were floating in the air is desirable so that the players can pinch them easily. Thus, we used an autostereoscopic display in which a lenticular lens is used to cover the liquid crystal display of a PC. As a result, each piece of the board game looks as if it were popping out of the 3D display screen, without the need for the player to wear special glasses. In addition, we use a Leap Motion Controller, a motion-capture device that is particularly suitable for capturing the position and movement of fingers so that a computer can recognize where in the 3D space the fingers are and whether the fingers are pinching a piece or not. Therefore, the user can operate the piece easily and intuitively.
