Classification: CPC G | IPC G

Claim 17:
18. A method for determining a movement trajectory, applicable to a processor in an electronic device comprising a body, a light-emitting component, a photosensitive component, a light-emitting control component, and the processor, wherein the light-emitting component, the photosensitive component, the light-emitting control component, and the processor are all disposed in the body, the photosensitive component is connected to the processor, and the light-emitting control component is connected to the light-emitting component, the method comprising:
acquiring optical information about reflected light, wherein the optical information is information acquired by the photosensitive component in response to receiving reflected light of probe light emitted by the light-emitting component, and the probe light emitting by the light-emitting component is controlled by the light-emitting control component, wherein the light-emitting control component comprises a pressure sensor disposed in a pressure sensing region on the body, the pressure sensor being configured to control the light-emitting component to emit the probe light in response to a pressure on the pressure sensing region being greater than a pressure threshold; and
determining a movement trajectory of the light-emitting component based on the optical information.
