Abstract
A tracking device including an image sensor, a light source and a processor is provided. The image sensor senses reflected light or scattered light formed by the light source illuminating a work surface. The processor calculates a trace of the tracking device according to one of the reflected light and the scattered light that generates more apparent image features so as to increase the adaptable work surfaces.
