Game board device

A go board game device capable of identifying go stones of distinct luminance contrast disposed thereon, the go board game device comprising:

• a go board defining three hundred sixty one intersections on an outer surface thereof and having a plurality of detection regions that are respectively arranged at the intersections, wherein each of the detection regions is selectively recognizable between (a) an unoccupied mode when none of the go stones are placed thereon and (b) an occupied mode when one of the go stones is placed thereon;
• a plurality of optical identification modules facing an inner surface of the go board and respectively corresponding in position to the detection regions, wherein each of the optical identification modules includes:
• a light emitter configured to emit light toward the corresponding detection region;
• and
• a light receiver corresponding in position to the light emitter;
• wherein the detection regions of the go board are configured to allow light emission from the light emitter of the corresponding one of the plurality of optical identification modules to pass through;
• wherein, when one of the detection regions is in the occupied mode, the light receiver of the corresponding optical identification module receives the light emission that is emitted from the light emitter of the corresponding optical identification module and that is reflected by the corresponding go stone, and reads a reflected luminance value of the corresponding go stone;
• a processing module electrically coupled to the optical identification modules and configured to determine a stone type of the go stones occupying one of the corresponding detection regions based on one of two types of the reflected luminance value;
• and
• a calibration button electrically coupled to the processing module, pressable to allow the processing module to drive the optical identification modules to obtain reflected luminance values of both types of the go stones, thereby enabling luminance contrast calibration for the go stones of different materials.
