The touch sensing device 110 may be disposed on the top surface, so that the user's finger can input touch operations through the touch sensing device 110. The touch sensing device 110 has a function of recognizing a user's finger, and can support single-finger, two-finger, or multi-finger touch operations, and different touch operations correspond to different input instructions. In this embodiment, the touch-sensing device 110 can recognize the number and touch position of the user's input touch operation. When the user's finger exists on the touch-sensing device 110, the position of the finger changes (for example, the finger on the touch-sensing device When sliding), the input touch track can be determined according to the touch position of the finger at each moment. The touch sensing device 110 is electrically connected to the controller 130, and sends the acquired finger number and touch position to the controller 130.

The working principle of the optoelectronic device 120 for acquiring the movement trajectory of the input device may be that there is a light emitting diode inside the optoelectronic device, and the light emitted by it can illuminate the bottom surface of the input device. After that, part of the light reflected back from the bottom surface of the input device passes through a set of optical lenses and is transmitted to a light-sensing device (micro-imager) for imaging. In this way, when the input device moves, its movement trajectory will be recorded as a set of high-speed continuous images captured and analyzed by a dedicated image analysis chip (DSP, digital microprocessor) inside the optoelectronic device. The chip analyzes the changes of the position of the feature points on these images to determine the moving direction and moving distance of the mouse arrow, thereby determining the moving trajectory of the input device. The optoelectronic device 120 is electrically connected to the controller 130, and can send the acquired movement trajectory of the input device to the controller 130 in real time.
