Abstract:
1. A mouse with in-the-air positioning function, which receives a directional light from an external illuminator, comprising: a first image sensor; a first light source, which lights at a lighting frequency to thereby provide the first image sensor to capture an image on a mouse pad or surface; a first memory, which stores the image captured by the first image sensor; a processing unit, which compares the image with a reference image for providing a cursor of coordinate positioning on a screen with respect to the mouse; a second image sensor, which receives the directional light from the external illuminator, converts the directional light received into an electrical signal, and produces a directional image corresponding to the directional light based on the electrical signal; and a second memory, which stores the directional image produced by the second image sensor; wherein when the mouse is airborne, the processing unit enables the second image sensor in order to obtain a rotating angle of the directional light by analyzing the directional image and to refer to the rotating angle of the directional light as the cursor of coordinating positioning.
