EvalCam detects Go board from real-time video and prepares the board configurations for users on the fly. Manual settings are no longer needed. Users can see the board status data, such as; territory evaluation, next move candidates, win rate, score lead by each player instantly. EvalCam does not use the user's device photo data. It only uses the camera (with the user's permission) to video scan a Go board configuration (the position of pieces on the board) and the video data does not leave the user's device. User privacy is 100% guaranteed.
