[0040] The working principle of a current optical mouse is as follows: light emitted from a light-emitting diode illuminates the bottom surface of the mouse. The reflected light is focused by an optical lens and transmitted to an optical sensor to form an image. When the mouse moves, its movement trajectory is recorded as a series of high-speed captured images. These images are then transmitted to an interface microprocessor (DSP) for analysis and processing. By comparing the positional changes of feature points in the images, the mouse's movement speed and direction are calculated, and this information is transmitted to the computer to control the movement of the cursor on the screen.

[0041] The working principle of existing gesture recognition devices is as follows: A camera identifies the user's hand gestures, and then preprocesses the images, performing noise reduction and filtering to improve data quality. Next, gesture features (such as finger position and movement trajectory) are extracted from the preprocessed images, and machine learning or pattern recognition algorithms are used for gesture recognition. Finally, the recognized gesture information is transmitted to the corresponding computer to enable interaction with the user.

[0042] Please see Figures 1 to 6 This embodiment provides a mouse with gesture recognition function, including a mouse shell 1 and a base plate 2. The mouse shell 1 houses a photoelectric sensor 3, a gesture recognition sensor 4, an accelerometer / gyroscope 5, a sensor switching controller 6, and a control motherboard 7. The photoelectric sensor 3 and the gesture recognition sensor 4 are located in the middle of the interior of the mouse shell 1. The photoelectric sensor 3 has a light emitting end and a light receiving end. The sensor switching controller 6 is connected to the photoelectric sensor 3, the gesture recognition sensor 4, the accelerometer / gyroscope 5, and the control motherboard 7. The sensor switching controller 6 controls the opening and closing of the photoelectric sensor 3 and the gesture recognition sensor 4 according to the change in the placement angle of the mouse shell 1 detected by the accelerometer / gyroscope 5. The base plate 2 includes a placement part 201 and a transparent part 202.

[0043] When the base plate 2 is mounted on the bottom of the mouse shell 1, the photoelectric sensor 3 faces vertically downwards towards the transparent part 202. The sensor switching controller 6 activates the photoelectric sensor 3 and deactivates the gesture recognition sensor 4 based on the change in the placement angle of the mouse shell 1 detected by the accelerometer / gyroscope 5, entering mouse mode. In mouse mode, the light-emitting end of the photoelectric sensor 3 continuously emits infrared light of a certain frequency. The emitted infrared light is reflected back by the bottom surface and received by the light-receiving end of the photoelectric sensor 3 to form an image. When the mouse moves, its movement trajectory is recorded as a series of high-speed captured continuous images. These images are then transmitted to the microprocessor (DSP) of the control motherboard 7 for analysis and processing. By comparing the positional changes of feature points in the images, the mouse's movement speed and direction are calculated, and this information is transmitted to the computer to control the cursor movement on the screen. Furthermore, by setting the transparent part 202, the base plate 2 protects the internal electronic components of the mouse shell 1 while ensuring their normal operation, without affecting the normal operation of the mouse.

[0044] When the mouse shell 1 is flipped and placed on the base plate 2's placement section 201, the gesture recognition sensor 4 faces outward at a certain tilt angle. Based on the change in the placement angle of the mouse shell 1 detected by the accelerometer / gyroscope 5, the sensor switching controller 6 activates the gesture recognition sensor 4 and deactivates the photoelectric sensor 3, entering gesture recognition mode. In gesture recognition mode, the recognition of user gestures by the gesture recognition sensor 4 provides more intuitive solutions for complex situations. Whether it's zooming in and out of images, controlling a drawing pen, 3D modeling, or controlling a robotic arm, it can handle these tasks effectively, significantly improving the user experience.

[0045] The mouse with gesture recognition function provided in this embodiment, through structural innovation, can present two usage modes: mouse mode and gesture recognition mode, to meet the diverse usage needs of users. By integrating the optical mouse and gesture recognition device into one device, the desktop space occupied is reduced, and the cumbersome need to connect multiple peripherals is also avoided. By setting an accelerometer / gyroscope 5 to detect changes in the placement angle of the mouse shell 1, the working mode (mouse mode or gesture recognition mode) is automatically switched, improving the convenience and flexibility of use. Whether performing regular mouse operations or complex gesture recognition operations, users can quickly switch on the same device without changing devices, thereby improving work efficiency. Compared with purchasing two separate devices, the purchase and maintenance costs of the mouse with gesture recognition function are lower.

[0046] Please see Figure 1 , Figure 2 , Figure 4 In one embodiment, a placement plane 101 is provided at the rear end of the upper surface of the mouse shell 1. The upper surface of the placement part 201 is flat, and the tilt angle of the placement plane 101 is 30-60°. By providing a placement plane 101 with a tilt angle of 30-60° at the rear end of the upper surface of the mouse shell 1, and setting the upper surface of the placement part 201 to be flat, when the mouse is flipped and placed on the placement part 201 of the base plate 2, the gesture recognition sensor 4 inside faces the user at this specific tilt angle. This tilt angle range is neither too steep, making it difficult for the user to make gestures comfortably, nor too gentle, affecting the accuracy of gesture recognition, allowing the user to perform gesture control in a natural and comfortable way without adjusting their hand posture or position. Preferably, the tilt angle of the placement plane 101 is 45°.

[0047] Please see Figure 2 , Figures 4 to 6In one embodiment, a battery 8 is disposed inside the mouse shell 1, and a wireless charging receiving coil 9 is disposed inside the placement surface 101 of the mouse shell 1. Both the battery 8 and the wireless charging receiving coil 9 are connected to the control motherboard 7. A wireless charging transmitting coil 10 and a charging control board 11, which cooperate with the wireless charging receiving coil 9, are disposed inside the placement portion 201 of the base plate 2. A charging interface 12 for connecting to an external power source is disposed on one side of the placement portion 201. The charging control board 11 is connected to the wireless charging transmitting coil 10 and the charging interface 12, respectively. By disposing of the battery 8 inside the mouse shell 1, power is provided for various functions of the mouse. Simultaneously, the wireless charging receiving coil 9 is cleverly integrated inside the placement surface 101 of the mouse shell 1. When the mouse shell 1 is placed on the placement portion 201 of the base plate 2, which supports wireless charging, it can receive wireless charging signals from the base plate 2 and convert electrical energy into electrical energy in the battery 8.

[0048] In one embodiment, a first magnetic element is provided inside the placement surface 101 of the mouse shell 1, and a second magnetic element is provided inside the placement portion 201 of the base plate 2, which is magnetically connected to the first magnetic element. Through this magnetic connection, the mouse shell 1 can be stably placed on the base plate 2 after being flipped over, preventing it from slipping due to slight touches or vibrations. This not only improves the user experience but also ensures the stability of the mouse shell 1 during charging or gesture control. Furthermore, the magnetic force of the magnetic element guides the mouse shell 1 to quickly and accurately position itself on the placement portion 201 of the base plate 2, automatically aligning it. Users do not need to spend extra time and effort to ensure the mouse shell 1 is placed correctly, thus improving the user experience.

[0049] In addition, in the above embodiments, the first magnetic component may be a positive magnet and the second magnetic component may be a negative magnet; or the first magnetic component may be a negative magnet and the second magnetic component may be a positive magnet; or the first magnetic component may be a magnet and the second magnetic component may be an iron block; or the first magnetic component may be an iron block and the second magnetic component may be a magnet.

[0050] Please see Figures 2 to 4 In one embodiment, the outer wall of the mouse shell 1 protrudes downward to form a U-shaped mounting portion 102, and the outer contour of the transparent portion 202 is U-shaped. The transparent portion 202 can be slidably mounted with the mounting portion 102. The mounting portion 102 provides a stable mounting frame for the transparent portion 202 and allows the transparent portion 202 to slide inside it, thereby realizing quick assembly or separation of the mouse shell 1 and the base plate 2.

[0051] Specifically, the inner wall of the assembly part 102 is provided with a groove 1021, the two ends of which extend to the two ends of the assembly part 102, providing a clear trajectory for the sliding of the transparent part 202. The outer wall of the transparent part 202 is provided with a protrusion 2021 that cooperates with the groove 1021. The tight cooperation between the protrusion 2021 and the groove 1021 ensures the stability and smoothness of the transparent part 202 during the sliding process. At the same time, the provision of the protrusion 2021 and the groove 1021 also limits the range of movement of the transparent part 202, preventing it from accidentally falling off the assembly part 102.

[0052] In some specific embodiments, the transparent portion 202 is made of a transparent material, such as glass, acrylic, or high-quality plastic, etc.

[0053] Please see Figure 5 In one embodiment, the mouse casing 1 houses a Bluetooth module 13 for communication with a computer, and the Bluetooth module 13 is connected to the control motherboard 7. The Bluetooth module 13 is a low-power, short-range wireless communication technology module that enables wireless data transmission between the mouse and the computer. The biggest advantage of Bluetooth connectivity is wireless freedom; users don't need to worry about cables and can move the mouse more flexibly. Furthermore, Bluetooth connectivity has low power consumption, which helps extend the mouse's battery life. Bluetooth connectivity makes the mouse particularly suitable for scenarios requiring high mobility and flexibility, such as home entertainment and office meetings. It is also suitable for users who want to reduce desktop clutter and pursue a minimalist style.

[0054] Please see Figure 7 In another embodiment, a USB interface 14 for connecting and communicating with a computer can also be provided on the mouse casing 1, and the USB interface 14 is connected to the control motherboard 7. Connecting and communicating with a computer via a wired connection through the USB interface 14 is one of the most common connection methods between a computer and external devices. USB connections have advantages such as stability, reliability, and high transmission speed. Because it is a wired connection, there are no signal interference or delay issues, ensuring the accuracy of mouse operation. Furthermore, the USB interface 14 has wide compatibility and can be connected to almost any computer with a USB port.
