Optical mouse and method for performing configured function thereof

An optical mouse, comprising:

• a control unit;
• an optical sensing unit electrically connected to the control unit;
• and
• a shutter unit disposed between a light emitting unit and a light guiding unit;
• wherein when the shutter unit is in a non-light-blocking state, the light emitting unit emits light toward a tracing surface, the optical sensing unit senses light reflected by the tracing surface and transfers optical data to the control unit, and the control unit generates a pointer control signal of movement of a pointing cursor based on the optical data;
• wherein when the shutter unit is in a light-blocking state, the shutter unit blocks light emitted by the light emitting unit toward the light guiding unit, the optical sensing unit senses a darkness and transfers darkness data to the control unit, and the control unit performs a configured function based on the darkness data.

A method for performing a configured function of an optical mouse, wherein the optical mouse is provided with a control unit, an optical sensing unit, and a light emitting unit, and the control unit is electrically connected to the optical sensing unit, the method comprising:

• a switch unit being electrically connected to the light emitting unit, and the switch unit being in a turn-off state to cause the light emitting unit to stop emitting the light;
• sensing a darkness and transferring darkness data to the control unit by the optical sensing unit;
• and
• performing the configured function based on the darkness data by the control unit.

A method for performing a configured function of an optical mouse, wherein the optical mouse is provided with a control unit, an optical sensing unit, and a light emitting unit, and the control unit is electrically connected to the optical sensing unit, the method comprising:

• a shutter unit being used to block light outputted by the light emitting unit, the shutter unit being in a light-blocking state to cause the shutter unit to block light emitted by the light emitting unit toward a light guiding unit;
• sensing a darkness and transferring darkness data to the control unit by the optical sensing unit;
• and
• performing a configured function based on the darkness data by the control unit.
