The "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist.

[0040] Figure 1 This application provides a signal recognition device for a smart terminal, comprising:

[0041] like Figure 4 Keyboard module 1 shown;

[0042] The substrate 2 is disposed below the keyboard module 1;

[0043] A gesture sensing module 3 is disposed on the substrate 2 and is used to detect gesture signals generated by user gesture operations;

[0044] A mouse sensing module 4 is disposed on the substrate 2 and is used to detect mouse operation signals generated by user gesture operations.

[0045] The processing module 5 is disposed on the substrate 2. The gesture sensing module 3 and the mouse sensing module 4 are both electrically connected to the processing module 5. The processing module 5 is used to receive gesture signals from the gesture sensing module 3 and mouse operation signals from the mouse sensing module, and convert the gesture signals and the mouse operation signals into control commands and transmit them to the control terminal.

[0046] like Figure 1 As shown, in this embodiment, a gesture sensing module 3 and a mouse sensing module 4 are located below the keyboard module 1. That is, keyboard input function, mouse input function and gesture operation input function are integrated on the keyboard module. The gesture sensing module 3 and the mouse sensing module 4 are hidden below the keyboard module 1. Without increasing the size of the keyboard module 1, multiple signal input and recognition methods of the smart terminal are realized, providing users with multiple signal input methods that are applicable to different application scenarios.

[0047] Generally, the substrate 2 is placed on the bottom shell 6, that is, the substrate is placed between the keyboard module 1 and the bottom shell 6, and the keyboard module 1 and the bottom shell 6 protect the substrate 2.

[0048] In this embodiment, the sensing module can be divided into two parts: a gesture sensing module 3 and a mouse sensing module 412. Furthermore, the gesture sensing module 3 in this embodiment can be a gesture detection signal specifically used to detect gesture operations, while the mouse sensing module 412 detects mouse operation signals used to implement mouse movement, single click, double click, left click, right click, and other operations. Further, as... Figure 6 and 7As shown, the gesture sensing module 3 and mouse sensing module 4 in this embodiment can be arranged in a matrix or other manner and are mounted on the substrate 2. It is easy to understand that the more gesture sensing modules 3 and mouse sensing modules 4 are arranged per unit area, the more detection signals (i.e., gesture detection signals or mouse operation signals) can be acquired, allowing the post-processing module 5 to more accurately identify the specific operation, thus making the generation of control commands more precise. The layout density of the gesture sensing modules 3 and mouse sensing modules 4 can be selected according to the actual situation of the application device of the signal recognition device of the smart terminal in this embodiment, and is not specifically limited here. By combining the gesture sensing module 3 and mouse sensing module 4 through the signal recognition device of the smart terminal in this embodiment, a new, more natural and intuitive interaction method can be provided to the user. This design integrates gesture sensing technology into a traditional mouse, allowing users not only to perform traditional click and movement operations with the mouse, but also to perform more complex tasks through gesture control.

[0049] The gesture sensing module 3 and the mouse sensing module 4 can communicate with the processing module 5 via an electrical connection. This electrical connection can be a ribbon cable connection. The gesture sensing module 3 and the mouse sensing module 4 can actively emit radio wave signals. When these radio waves encounter a hand, they are reflected. The gesture sensing module 3 and the mouse sensing module 4 can then receive the reflected radio wave signals and use them as gesture detection signals. These signals are then sent to the processing module 5 via the electrical connection between the gesture sensing module 3 and the mouse sensing module 4 and the processing module 5. Figure 5 The processing module 5 on the substrate 2 shows signal processing. The processing module 5 determines the specific gesture by analyzing the time delay, frequency changes, and phase changes of the received gesture detection signal. Furthermore, during gesture recognition, algorithms can process this data to identify the user gesture corresponding to the gesture recognition signal. Gestures can include, but are not limited to, waving, swiping, pinching, and rotating. Moreover, the processing module 5 can pre-determine the one-to-one correspondence between different gestures and control commands, thereby obtaining the corresponding control commands based on the determined user gestures.

[0050] In this embodiment, the processing module 5 can be an electromagnetic wave energy absorption ratio integrated circuit 12. Furthermore, the gesture sensing module 3 and the mouse sensing module 4 can communicate with the electromagnetic wave energy absorption ratio integrated circuit 12 (i.e., SAR IC, Specific Absorption Ration IC) via electrical connection.

[0051] The signal recognition device of the smart terminal in this embodiment can obtain the corresponding control command by detecting the gesture operation, thereby realizing the purpose of control by gesture operation. This achieves the technical effect of control without the need for an input device, and solves the technical problem of cumbersome operation of electronic devices in related technologies.

[0052] like Figure 2 As shown, as an optional implementation, the signal recognition device of the aforementioned smart terminal includes a gesture sensing module 3 and a mouse sensing module 4, both located within the orthographic projection area of ​​the keyboard module 1 relative to the substrate 2. The gesture sensing module 3 is positioned around the mouse sensing module 4. Figure 2 As shown, the gesture sensing module 3 and the mouse sensing module 4 can be located below the keyboard module 1. Further, as... Figure 1 As shown, when the mouse sensing module 4 is rectangular, the gesture sensing module 3 can be a larger rectangular frame surrounding the mouse sensing module 4. The gesture sensing module 3 is positioned around the mouse sensing module 4. This ensures that the gesture sensing area covers a larger area around the mouse, improving the sensitivity and accuracy of gesture recognition.

[0053] As an optional implementation, the signal recognition device of the aforementioned smart terminal further includes: a first sensing switching module, electrically connected to the gesture sensing module 3, used to turn the gesture sensing module 3 on or off to enable or disable the detection of the gesture signal; and / or a second sensing switching module, electrically connected to the mouse sensing module 4, used to enable or disable the mouse sensing module 4 to enable or disable the detection of the mouse operation signal. The first sensing switching module is a component for controlling and managing the gesture sensing module 3. Its main function is to disable the gesture sensing module 3 under specific circumstances to stop detecting gesture signals. The second sensing switching module is a component for controlling and managing the mouse sensing module 4. Its main function is to disable the mouse sensing module 4 under specific circumstances to stop detecting mouse operation signals. By setting the first and / or second sensing switching modules to be disabled, system energy efficiency can be improved, unnecessary interference reduced, and a better user experience provided in certain scenarios (e.g., scenarios where control is not required). Furthermore, the first sensing switching module can control the working state of the gesture sensing module 3 and the mouse sensing module 4 through electrical connection, so that they enter a low-power mode or are completely turned off when not needed.

[0054] Optionally, the electrical connection between the first sensing switching module and / or the second sensing switching module and the gesture sensing module 3 and the mouse sensing module 4 can be a hardware connection. The first sensing switching module and / or the second sensing switching module communicate with the gesture sensing module 3 and the mouse sensing module 4 through the electrical connection, and can be a direct physical connection (such as a wire) or through a bus interface (such as I2C, SPI, UART communication serial port).

[0055] The first and / or second sensor switching modules can determine when to disable the gesture sensing module 3 based on various triggering conditions, such as: User input: The user manually selects to disable it via a button, switch, or other interface. System status: The system automatically disables it when it detects that the gesture sensing function is not currently needed. Time setting: A time period is set, during which the module automatically disables it. Environmental conditions: The module automatically disables it when specific environmental conditions (such as changes in light or temperature) are detected.

[0056] Therefore, by setting the first and / or second sensing switching modules, the following technical effects can be achieved: energy saving: when gesture or mouse sensing functions are not used, the first and / or second sensing switching modules can significantly reduce power consumption and extend the device's battery life. Reduced interference: in some cases, the gesture sensing module 3 and the mouse sensing module 4 may be affected by other signals in the environment; disabling these modules can avoid such interference, improving system stability and reliability. User control: allowing users to manually enable or disable the gesture sensing function as needed, improving the user experience.

[0057] As an optional implementation, as described above in the signal recognition device of the smart terminal, the sensing module includes at least one antenna for transmitting signals. That is, in this embodiment, the sensing module 1 includes at least one antenna, which is an antenna for transmitting radio wave signals. Optionally, the antenna can be an antenna built into the electronic device (e.g., a smartphone, tablet, laptop, etc.) on which the signal recognition device of the smart terminal of this embodiment is installed, or it can be an additional antenna.

[0058] As an optional implementation, such as the signal recognition device of the aforementioned smart terminal, the sensing module adopts one of the following: a printed circuit board or a flexible printed circuit board. Specifically, when the sensing module 1 adopts a printed circuit board, the following advantages can be achieved: high reliability, the rigid structure makes the printed circuit board more reliable in long-term use; easy maintenance, the rigid structure of the printed circuit board makes repair and component replacement more convenient; suitable for mass production, the manufacturing process of printed circuit boards is mature and suitable for mass production. When the sensing module 1 adopts a flexible printed circuit board, the following advantages can be achieved: high flexibility, the flexible printed circuit board can be bent and folded, suitable for complex spatial layouts; thin and light, the flexible printed circuit board is small in size and light in weight, suitable for compact designs; high reliability, when using a flexible printed circuit board, the use of connectors can be reduced, thereby improving the overall reliability of the hover gesture recognition module.

[0059] As an optional implementation, such as the signal recognition device of the aforementioned smart terminal, the gesture sensing module 3 and the mouse sensing module 4 are disposed adjacently on the substrate 2. That is, the gesture sensing module 3 and the mouse sensing module 4 are positioned adjacent to each other on the substrate 2. Further, as... Figure 6 and Figure 7 As shown, the gesture sensing module 3 is located around the mouse sensing module 4. For example, when the mouse sensing module 4 is rectangular, the gesture sensing module 3 is the rectangular frame surrounding the mouse sensing module 4. Figure 6 As shown, in some embodiments, the gesture sensing module 3 is disposed along the inner periphery of the substrate 2.

[0060] According to another aspect of the embodiments of this application, an electronic device is also provided, including a signal recognition device for a smart terminal as described in any of the foregoing embodiments. That is, the electronic device in this embodiment has a built-in signal recognition device for a smart terminal as described in any of the foregoing embodiments, thereby enabling the electronic device to achieve hover gesture recognition control.

[0061] For example: Figure 2 As shown, when the user executes Figure 2When gesture A is shown, the gesture sensing module 3 can actively emit radio wave signals. When the radio waves encounter gesture A, they will be reflected. The sensing module can then receive the reflected radio wave signal 'a' corresponding to gesture A and use the received reflected radio wave signal 'a' as the gesture detection signal I. Then, through the electrical connection between the gesture sensing module 3 and the electromagnetic wave energy absorption ratio integrated circuit, the gesture detection signal I is sent to the processing module 5 for signal processing. The processing module 5 analyzes the time delay, frequency change, and phase change of the received gesture detection signal I to determine that it is gesture A. Furthermore, during gesture recognition, algorithms can process this data to identify the user gesture corresponding to the gesture recognition signal. Gestures can include, but are not limited to, waving, swiping, pinching, and rotating. Moreover, the electromagnetic wave energy absorption ratio integrated circuit can pre-determine the one-to-one correspondence between different gestures and control commands. Therefore, based on the determined user gesture A, the corresponding control command, a page switching command, can be obtained. Finally, the electronic device can respond to the page switching command to switch the current page.

[0062] Similarly, when the user executes Figure 3 When the mouse is controlled as shown, the mouse sensing module 4 can detect the corresponding mouse operation signal by detecting gesture B, and then transmit the mouse operation signal to the electromagnetic wave energy absorption ratio integrated circuit. The electromagnetic wave energy absorption ratio integrated circuit can then convert the mouse operation signal into a corresponding control command. For example, when the mouse operation signal is a finger sliding to the left, the corresponding control command is a command to move the mouse cursor to the left. In this way, the electronic device can respond to the command to move the mouse cursor to the left and control the mouse cursor to move to the left.

[0063] As an optional implementation, in the aforementioned electronic device, the gesture sensing module 3 and the mouse sensing module 4 are located below the sensing area of ​​the electronic device. Specifically, in this embodiment, the gesture sensing module 3 and the mouse sensing module 4 can be pre-set areas on the electronic device that can be used to sense gestures. These sensing areas can be, for example, the screen, keyboard, etc. By placing the sensing modules below the sensing area of ​​the electronic device, the sensing area can be effectively hidden, making the electronic device more aesthetically pleasing. Furthermore, the built-in sensing area avoids the obstruction of other input / output devices caused by external sensors.

[0064] As an optional implementation, the aforementioned electronic device includes at least one antenna for signal transmission, with a sensing module integrated on the antenna's electrodes. The sensing module includes a gesture sensing module 3 and a mouse sensing module 4. In other words, in this case, the antenna electrodes can serve as both the gesture sensing module 3 and the mouse sensing module 4, thereby achieving the purpose of sensing gestures or mouse operations.

[0065] As an alternative implementation, in the case of the aforementioned electronic device, where the electronic device is a touch-screen computing device, the sensing module is located below the screen of the electronic device. When the electronic device has a screen, it can be an external tablet, smartphone, laptop, etc. In this case, the sensing module can be located around the screen of the electronic device; that is, both the gesture sensing module 3 and the mouse sensing module 4 can be located around the screen, allowing the user to perform gesture operations in front of the screen.

[0066] Furthermore, when an electronic device includes both a keyboard and a screen, the sensing module can be placed below the keyboard or around the screen. Additionally, the sensing module can be placed in a location where an antenna is located within the electronic device, thereby increasing the signal transmission and reception of the sensing module and improving the accuracy of gesture detection.
