Abstract
A two-dimensional navigation module of a cursor controller includes a top plate, a first rod, a sliding roller sleeved at the first rod, and a first OTS sensor. The top plate has an elongated groove recessed thereon. The first rod is arranged in the groove. Two opposite ends of the first rod are fastened to the top plate. The sliding roller is movable along the first rod between a first position and a second position, and the sliding roller is spinable along the first rod in a range of 0˜360 degrees. When the sliding roller is moved, a center segment of the first rod keeps touching the sliding roller. The first OTS sensor is arranged under the center segment of the first rod for detecting at least one of a moving distance and a spinning angle of the sliding roller.
