A mouse with coordinate and suspension positioning functions, which receives a directional light produced by an external illuminator. A second image sensor receives and converts the directional light into an electrical signal, and accordingly produces a directional image corresponding to the directional light. A second memory stores the directional image. When an image captured by a first image sensor cannot be focused, a processor enables the second image sensor and the second memory in order to analyze the directional image and obtain a rotating angle of the directional light for further fulfilling a coordinate positioning.
