Abstract: An optical tracking device is used to track a target object. An outer surface of the target object is divided into a first region and a second region adjacent to each other, and a marker is disposed on the first region. The optical tracking device includes an optical sensor and an operation processor. The optical sensor has auto exposure function and is adapted to acquire a detection image containing at least one of the first region and the second region. The operation processor is electrically connected to the optical sensor and adapted to analyze variation of an exposure parameter of the auto exposure function for determining whether the first region is appeared in the detection image, so as to acquire an operation datum of the target object.
