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 pen mouse includes a housing, a rotatable actuator, an optical sensor and a processor. The rotatable actuator is movably disposed inside the housing along a structurally longitudinal direction and a structurally horizontal direction of the housing. The optical sensor is adapted to detect surface reflection of the rotatable actuator. The processor is electrically connected with the optical sensor and adapted to compute a rotating direction, a rotating angle and depth variation of the rotatable actuator via analysis of the surface reflection.

Abstract: A pen mouse with an inclining compensation function includes an optical sensor, a sensor array, a pen tip and a processor. The optical sensor is adapted to sense a relative movement of an object. The sensor array has a plurality of sensing units. The pen tip is connected to the sensor array and adapted to activate at least one of the plurality of sensing units when being pressed by the object. The processor is electrically connected with the sensor array. The processor is adapted to compute a trace of the pen mouse via analysis of the relative movement and further to compensate the trace via analysis of the activated sensing unit.

Abstract: There is provided a capacitive communication system including an object and a capacitive touch panel. The object includes a plurality of induction conductors configured to have different potential distributions at different time intervals by modulating respective potentials thereof. The capacitive touch panel includes a plurality of sensing electrodes configured to form a coupling electric field with the induction conductors to detect the different potential distributions at the different time intervals. When the different potential distributions match a predetermined agreement between the object and the capacitive touch panel, a near field communication is formed between the object and the capacitive touch panel.

Abstract: A navigation device with distance detecting function can utilize a distance detecting mechanism to detect a distance relative to a working surface. The distance detecting mechanism includes a base, a connecting component, a feature unit and a detection unit. The connecting component partly protrudes from the base. The connecting component optionally contacts against or is spaced from the working surface to generate a distance variation relative to the base along an axial direction. The feature unit is disposed on the connecting component. The detection unit is connected to the base. The detection unit can detect parameter difference of the feature unit according to the distance variation of the connecting component relative to the base, so as to determine the distance between the working surface and a bottom of the base via the parameter difference.
