[0034] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0035] See also Figure 1 The gesture page turning system of this embodiment at least includes: a plurality of non-contact gesture recognition sensor modules (e.g. Figure 1 The non-contact gesture recognition sensor module A, non-contact gesture recognition sensor module B, non-contact gesture recognition sensor module C, ...), processor module, display, power module; wherein multiple non-contact gesture recognition sensor modules are fixedly installed facing the front of the display, so as to detect the user's gesture changes from the front of the display (for example, the user's gesture moves from left to right, from right to left, from bottom to top, from top to bottom, etc.), and each non-contact gesture recognition sensor module is respectively connected to the processor module through a communication cable, so that the processor module monitors the signal strength of each non-contact gesture recognition sensor module at any time; the processor module is configured to send book turning instructions in different directions to the display according to the order in which the corresponding trigger signals are recognized by the multiple non-contact gesture recognition sensor modules, that is, the processor pre-stores There is a correspondence between the triggering sequence of different non-contact gesture recognition sensor modules and the awakening of different page turning instructions. Pre-storing a preset correspondence in the processor module to trigger different instructions is a relatively mature prior art, which will not be described in detail here. For example: assuming that there are only two non-contact gesture recognition sensor modules arranged on the left and the right, the comparison table records that within a certain gesture recognition cycle, the trigger signal of the left non-contact gesture recognition sensor module is first received, and then the trigger signal of the right contact gesture recognition sensor module is received, which indicates that the corresponding awakening is a page turning instruction from left to right, otherwise, it indicates that the corresponding awakening is a page turning instruction from right to left; the display is used to communicate with the above-mentioned processor module through a communication cable and execute its book turning instruction; the power supply module is used to provide an adaptive power supply voltage to each non-contact gesture recognition sensor module, the processor module and the display through a power supply cable. That is to say, when the user makes a specific gesture in front of the display, his gesture makes multiple non-contact gesture recognition sensor modules recognize the corresponding trigger signal sequence, and then send book-turning instructions in different directions to the display. The display executes the book-turning instructions transmitted by the processor to realize the non-contact page-turning function of the display. It can also play preset sound effects when turning pages, giving users a fantastic and special interactive experience and increasing fun.

[0036] Specifically, the multiple non-contact gesture recognition sensor modules of this embodiment specifically include: a light receiving sensor arranged in the middle, three light emitting tubes that are not all in the same straight line, and the light emitting tubes can be infrared light emitting tubes, red light emitting tubes, green light emitting tubes, blue light emitting tubes, etc., which are not limited here. Preferably, the non-contact gesture recognition sensor module of the gesture book turning system of this embodiment is mainly a Si114x series gesture sensor.

[0037] In some other embodiments, please see Figure 2 , Figure 2 This is an embodiment of an electronic device including a gesture page turning system, in which the processor module, display, and power module are all integrated in the housing 100, and only the screen of the display and each non-contact gesture recognition sensor module are exposed toward the user side, so as to realize the viewing function of the display and the function of capturing the user's gesture through the non-contact gesture recognition sensor module. Figure 2 As shown in the middle dotted frame 400, the non-contact gesture recognition sensor module of the gesture book turning system of this embodiment specifically includes: an infrared receiving sensor 410 arranged in the middle, two infrared transmitting tubes (left infrared transmitting tube 420 and right infrared transmitting tube 430) on the same horizontal line, and the infrared receiving sensor 410 is arranged on the symmetric line of the line connecting the two infrared transmitting tubes (preferably, the infrared receiving sensor 410 is arranged at the midpoint of the line connecting the two infrared transmitting tubes) to reduce the error after the infrared receiving sensor 410 receives the infrared light emitted by the two infrared transmitting tubes and is reflected by the gesture, thereby improving the accuracy of reception and recognition. Usually, the non-contact gesture recognition sensor module of the gesture book turning system is fixedly installed in the frame of the housing 100.

[0038] In some other embodiments, when the non-contact gesture recognition sensor module specifically includes an infrared receiving sensor (Si114x sensor) arranged in the middle, and three infrared emitting tubes (light emitting tubes) that are not all in the same straight line, please refer to Figure 2As shown in the dotted frame 500, the contactless gesture recognition sensor module can be integrated and then embedded in the frame of the housing 100, or it can be used as a detachable module, which can be set according to actual needs. Further, the three infrared emitting tubes are fixedly installed in the same plane of the display to reduce the error of the infrared receiving sensor receiving the infrared light emitted by the three infrared emitting tubes after being reflected by the gesture, thereby improving the accuracy of reception and recognition. Specifically, it is assumed that the three infrared emitting tubes include: a first infrared emitting tube D1, a second infrared emitting tube D2, and a third infrared emitting tube D3; wherein the first infrared emitting tube D1, the second infrared emitting tube D2, and the infrared emitting tube D3 are fixedly located at the three vertices of a triangle in the same plane of the display; the infrared receiving sensor is at an equal distance from the three vertices of the triangle. Further, the infrared receiving sensor is located in the same plane where the first infrared emitting tube D1, the second infrared emitting tube D2, and the third infrared emitting tube D3 are fixedly located.

[0039] Specifically, the processor module of the gesture book turning system of this embodiment can be an X86 computer host. Furthermore, when the X86 computer host as a processor module monitors whether there is a trigger signal for multiple infrared emitting tubes, it can first perform identification signal processing on the infrared emitting tube reflection signal received by the infrared receiving sensor, and convert the analog signal into a digital signal through a high-precision analog-to-digital converter (ADC), and then transmit the digital signal to the X86 computer host for processing. After the X86 computer host recognizes the corresponding page turning instruction based on the digital signal, it transmits the page turning instruction to the interface circuit of the display, and the display executes the page turning instruction.

[0040] It should be noted that the SI114X series products, which are preferably non-contact gesture recognition sensor modules, have multiple high-sensitivity photodiodes (infrared emitting tubes are used in this embodiment) and a high-precision analog-to-digital converter (ADC). It takes less time (about 25.6ms) to measure the infrared LED that turns on the infrared emitting tube than other sensors. The shorter infrared emitting tube LED turn-on time enables the infrared emitting tube to measure and compensate for the infrared intensity in the surrounding environment and better identify gestures. Even under direct sunlight, it has the best high dynamic performance. It can achieve high operational accuracy. In actual work, such as Figure 3As shown in the figure, the SI114X sensor is placed in the middle, D1, D2, and D3 are three infrared emitting tubes, and the Si114x sensor cooperates with the three infrared emitting tubes to emit light in time. The sampling rate is generally set to 20-100Hz, and the hand wave time is about 100-300ms. The wrist wave can sample 10-30 times of data. The sampled data is usually uploaded to the host computer (X86 computer host) through the asynchronous receiver / transmitter UART (Universal Asynchronous Receiver / Transmitter) for data analysis. For example, when Figure 3 When the user gesture moves from right to left, the following is obtained: Figure 5 As shown in the waveform curve diagram, the first infrared emitting tube D1, the second infrared emitting tube D2, and the third infrared emitting tube D3 are triggered by the infrared light reflected by the user's gesture to the Si114x sensor. When the palm is waved from right to left, it first passes through the second infrared emitting tube D2, then the third infrared emitting tube D3, and finally the first infrared emitting tube D1. The palm reaches a peak in the direction of each infrared emitting tube. By calculating the time difference corresponding to the peak values ​​of the three infrared emitting tubes, it can be determined that the gesture is waving to the left; when the user's gesture moves from left to right, the following is obtained Figure 4 As shown in the waveform curve diagram, the first infrared emitting tube D1, the second infrared emitting tube D2, and the third infrared emitting tube D3 are triggered by the infrared light reflected by the user's gesture to the Si114x sensor. When the palm is waved from left to right, it first passes through the first infrared emitting tube D1, then the third infrared emitting tube D3, and finally the second infrared emitting tube D2. The palm reaches a peak in the direction of each infrared emitting tube. By calculating the time difference corresponding to the peak values ​​of the three infrared emitting tubes, it can be determined that the gesture is waving to the right; when the user gesture moves from top to bottom, the following is obtained Figure 6 As shown in the waveform curve diagram, the first infrared emitting tube D1, the second infrared emitting tube D2, and the third infrared emitting tube D3 are triggered by the infrared light reflected by the user's gesture to the Si114x sensor. When the palm is waved from top to bottom, it first passes through the second infrared emitting tube D2 and the first infrared emitting tube D1, and then passes through the third infrared emitting tube D3. The palm reaches a peak in the direction of each infrared emitting tube. By calculating the time difference corresponding to the peak values ​​of the three infrared emitting tubes, the downward wave of the gesture can be determined; when the user gesture moves from bottom to top, the following is obtained Figure 7 The waveform curve diagram shown is that the first infrared emitting tube D1, the second infrared emitting tube D2, and the third infrared emitting tube D3 are triggered after the infrared light reflected by the user's gesture to the Si114x sensor. When the palm is waved from bottom to top, it first passes through the third infrared emitting tube D3, and then passes through the second infrared emitting tube D2 and the first infrared emitting tube D1. The palm reaches a peak in the direction facing each infrared emitting tube. By calculating the time difference corresponding to the peak values ​​of the three infrared emitting tubes, the upward wave of the gesture can be determined.

[0041] In addition, if Figure 2 As shown, the gesture page turning system of this embodiment may also include: a bracket seat; wherein the bracket seat is specifically used to fix and install the display, processor module and power module, etc. Specifically, the bracket seat includes: a housing 100, a bracket 200, and a base 300; the housing 100 is used to fix and install the display, processor module and power module; the first end of the bracket 200 is vertically fixedly installed on the base 300, and the second end of the bracket 200 is fixedly installed on the housing 100, so as to meet the mobile office needs of public electronic devices in some public places (such as large conference halls, lecture halls, large classrooms, exhibitions, etc.), and rollers can be further added under the base 300 for easy movement. In other words, this embodiment can ensure that the mobile electronic device equipped with the gesture page turning system can ensure that the page turning function remains hygienic after it is realized, reduce the cross-infection of germs to different users through public electronic devices, and do not require the cooperation of remote controllers, mice, touch screens and other devices.
