Abstract: An optical detection system includes a marker product and an optical encoding device. The marker product includes a substrate and at least one structural portion. The structural portion has a first surface, a second surface and a dividing axis. The first surface and the second surface are arranged on opposite sides of the dividing axis. A sidelong direction aligning the first surface with the second surface is parallel to a moving direction between the optical encoding device and the marker product. The optical encoding device is disposed adjacent by the marker product. The optical encoding device includes an optical projector and an optical encoder. The optical projector is configured to project the optical detecting signal onto the marker product. The optical encoder is configured to receive an optical reflecting signal from the marker product and encode intensity variation of the optical reflecting signal into digital data.

Abstract: An electronic apparatus includes a structure and an optical navigation circuit. A first end of the structure is located inside the electronic apparatus and its second end corresponds to a user's control. The structure can be moved forward/backward in a specific direction and/or rotated in another direction. The optical navigation circuit captures reflection of a light emitting to the structure to detect displacement of the image along a specific axis of the structure, and determines the user's operating behavior as a specific operation according to a change of the sensed displacement of the image.

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.

Abstract: A navigation trace calibrating method and a related optical navigation device are utilized to transform a first trace line generated by the optical navigation device into a second trace line suitable for user operation. The navigation trace calibrating method includes establishing a reference coordinate system, reading and analyzing the first trace line, calculating a first offset of the first trace line relative to the reference coordinate system, defining an offset between the first trace line and the second trace line as calibration weight to acquire a second offset of the second trace line relative to the reference coordinate system, and calculating a value of the calibration weight according to the second offset and a length of the first trace line.
