Abstract: An optical detecting device includes a multi-axis instruction outputting mechanism and an optical detecting module, and shift of the multi-axis instruction outputting mechanism is determined accordingly. An actuating component of the multi-axis instruction outputting mechanism is moved in reciprocation at a first operating direction to output an instruction. The optical detecting module is disposed by the actuating component. An interval between the optical detecting module and the actuating component is varied according to a relative movement between the optical detecting module and the actuating component at a second operating direction, and the actuating component can be shifted between different gears. The optical detecting module determines the interval and related gearshift according to variation of a reflecting signal actuated by the actuating component, and utilizes the reflecting signal to acquire a movement of a feature point on the actuating component along the first operating direction to interpret the instruction.

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.

Abstract: The present disclosure illustrates an optical navigation chip. The optical navigation chip is disposed on an optical navigation module. The optical navigation module includes a light-emitting unit. The light-emitting unit provides a light beam to irradiate a surface of a displacement generating unit. The light beam has a low divergence angle to reduce scattering. The optical navigation chip includes a sensing array and a displacement calculating unit. The sensing array is disposed corresponding to the surface. The sensing array receives a reflected light beam which the surface reflects, and captures an image once every capturing interval based upon the reflected light beam. The displacement calculating unit calculates a relative displacement between the optical navigation chip and the surface according to the images.
