Abstract: A game board device is provided for carrying and identifying game pieces that are divided into different piece types. The game board device includes a board, a plurality of optically identifying modules, and a processing module electrically coupled to the optically identifying modules. The optically identifying modules respectively correspond in position to detection regions of the board. Each of the optically identifying modules includes a light emitter that can emit light toward the corresponding detection region and a light receiver that can receive light reflected by the corresponding detection region. When any one of the detection regions is in an unoccupied mode, the corresponding optically identifying module can emit an unoccupied signal. When any one of the detection regions is in an occupied mode, the corresponding optically identifying module enables an identification signal that corresponds to the piece type of the corresponding game piece to be emitted therefrom.

Abstract: A smart wearable device has a signal calibration function executed by a signal calibration method and applied to a finger, a limb and/or a neck of a user. The smart wearable device includes at least one physiological signal detector, at least one pressure detector and an operation processor. The at least one physiological signal detector is adapted to abut against a detection area of the user for detecting a physiological signal. The at least one pressure detector is disposed around the at least one physiological signal detector and adapted to detect a pressure value of the detection area. The operation processor is electrically connected with the at least one physiological signal detector and the at least one pressure detector. The operation processor is adapted to optimize the physiological signal when the pressure value exceeds a predefined pressure threshold.
