The cursor indicator

The invention relates to a cursor indicator, which is provided with an optical module and a scattering plate, wherein a luminous source of the optical module is used for generating an emitting light source, the emitting light source is emitted to the scattering plate to generate scattering light rays, the scattering light rays can intervene each other to generate light spots, interference light spots generated by the scattering light rays can move through moving the scattering plate, then, a sensor is used for detecting the direction, the speed and the distance of light spot moving, further, the light spot moving is converted into the cursor moving, a user can operate and control the displacement of the scattering plate by fingers without moving the whole cursor indicator, and the goal of indicating the cursor moving can be achieved.
