DETAILED DESCRIPTION

[0030] The technical solutions of the present disclosure will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure. In addition, the technical features involved in the different embodiments of the present disclosure described below can be combined with each other as long as they do not conflict with each other.

[0031] Nowadays, intelligent electronic devices have greatly facilitated people's lives, allowing users to interact with them to perform various control operations. For example, in fast food restaurants, intelligent management systems can efficiently connect front-end and back-end workstations. For example, after a customer places an order at the front-end, the back-end workstation device receives the user's order. After the food is served, the staff can operate the device to complete the order, and the management system configures the order to be served. Throughout this process, staff members need to interact with the workstation device to complete the same order processing operations.

[0032] Currently, human-computer interaction on workstations is primarily based on physical buttons and touchscreens. Physical buttons refer to physical keys, such as keyboards or buttons, that correspond to different functions, allowing workers to interact with the machine by tapping them. Touchscreens, on the other hand, refer to devices with touch-enabled displays, allowing workers to interact with the machine by tapping virtual buttons on the display.

[0033] This method requires direct contact between staff and equipment. As public health and safety are increasingly valued, staff touching equipment while handling food can easily cause cross-infection of bacteria, bringing risks to food hygiene and safety. On the other hand, it can easily lead to residual stains (such as oil stains) on the equipment, causing bacterial growth. Long-term residual stains will also affect the normal use of the equipment.

[0034] As a contactless human-computer interaction method, gesture recognition can avoid direct contact between users and equipment, thus preventing cross-infection of bacteria. It is particularly suitable for food workstations. In related technologies, there are various types of gesture recognition input devices, such as:

[0035] 1) Using an infrared camera to capture two-dimensional images and combining them with image recognition algorithms to identify user gestures. This technology requires a certain amount of computing power and only works well indoors, with poor robustness in scenes with strong light or complex backgrounds.

[0036] 2) Using depth sensors to collect three-dimensional gesture information and combining it with depth image detection algorithms to recognize gestures. This approach can provide more accurate gesture recognition, but it relies on expensive depth sensors and complex detection algorithms, which is relatively costly.

[0037] 3) Using cameras to capture images and combining them with machine learning algorithms such as deep learning to achieve real-time gesture recognition and classification. This approach offers better real-time gesture recognition, but it requires high computing power and is difficult to deploy on low-cost devices.

[0038] 4) Utilize multiple sensors (such as light sensors, cameras, and inertial sensors) to capture data and combine it with data fusion algorithms to achieve high-precision gesture recognition. This approach requires a large number of sensors and a more complex multimodal fusion algorithm to achieve data fusion, making it difficult to design and implement.

[0039] As can be seen from the above, gesture input devices in related technologies are inevitably limited by hardware and cost, making them difficult to implement on low-cost devices. Furthermore, these gesture input devices are generally integrated into electronic devices. Expanding gesture input functionality on existing devices is impossible and requires replacing the electronic device, which undoubtedly increases operating costs for businesses and merchants.

[0040] Based on this, an embodiment of the present application provides a gesture control component, which can be used as an extension component of an electronic device. By assembling and connecting with the electronic device, it expands the gesture input function of the electronic device and reduces the deployment cost of merchants in the form of a component.

[0041] Moreover, the gesture control component in this application uses multiple photosensitive devices to realize the switching of control logic, without the need for complex recognition algorithms, so the computing power requirements of the device are very low, and the expansion of gesture input functions can be achieved at extremely low cost, such as the deployment and implementation of gesture input devices.

[0042] Furthermore, the gesture control component in this application fully considers the differentiated needs of different devices and different scenarios, and sets gesture detection with adjustable angle and direction, so that it can meet the gesture control needs in various scenarios and is more adaptable.

[0043] Figures 1 to 5 The structure of the gesture control component in some embodiments of the present application is shown below. Figures 1 to 5 Provide explanation.

[0044] like Figure 1 As shown, in some embodiments, the gesture control component includes a shell 100, which refers to the main structure of the gesture control component. For example, the shell 100 can be a shell structure made of plastic and / or metal materials, and the gesture control function is realized by arranging corresponding electronic devices inside it.

[0045] exist Figure 1 In the example, the main body of the housing 100 is a roughly rectangular three-dimensional structure. Of course, those skilled in the art will understand that the outer structure of the housing 100 is not limited to Figure 1 For example, it can also be any other shape structure suitable for implementation, such as a sphere, a polyhedron, a special-shaped structure, etc., and this application does not limit this.

[0046] In the embodiment of the present application, the gesture control component further includes at least two photosensitive devices, which can be arranged at intervals on the housing 100 .

[0047] It is worth noting that in the embodiment of the present application, at least two photosensitive devices can be used to recognize user gestures. At the same time, a larger number of photosensitive devices can also be used, and the interaction logic between different photosensitive devices can be used to realize the recognition of a larger number of gestures.

[0048] exist Figures 1 to 5 In the example, only a gesture control component including two photosensitive devices is shown. It can be understood that in other implementation examples, the gesture control component can also include a larger number of photosensitive devices, such as 3, 4, 5, etc. This will be explained in the implementation below of this application and will not be described in detail here.

[0049] See also Figure 1 As shown, in this example, the gesture control component includes two photosensitive devices, namely Figure 1 As shown, the first photosensitive device 210 and the second photosensitive device 220 are spaced apart from each other on the housing 100 .

[0050] A photosensitive device refers to hardware that generates control electrical signals based on the principle of light sensing. For example, in some embodiments, the photosensitive device may be a light sensor that converts received light signals into electrical signals and, in combination with a signal processing algorithm, generates corresponding control signals based on the electrical signals.

[0051] In the embodiments of the present application, there is no limitation on the specific type of light sensor, and those skilled in the art can select any type of light sensor as needed. For example, in one example, the first photosensitive device 210 and the second photosensitive device 220 can both use diffuse reflection sensors. For example, in another example, the first photosensitive device 210 and the second photosensitive device 220 can both use mirror reflection sensors. For example, in yet another example, the first photosensitive device 210 and the second photosensitive device 220 can both use infrared light sensors. The specific parameters, models, and working principles of different types of sensors can undoubtedly be understood and fully implemented in combination with relevant technologies, and will not be elaborated in this application.

[0052] In the embodiment of the present application, the first photosensitive device 210 and the second photosensitive device 220 need to be spaced apart from each other on the housing 100 to ensure that the sensing ranges of the first photosensitive device 210 and the second photosensitive device 220 do not overlap.

[0053] It is understood that the photosensitive device has a certain sensing range. When an object enters the sensing range, the light within the range changes, and the photosensitive device can detect the corresponding electrical signal change. By setting the first photosensitive device 210 and the second photosensitive device 220 at an interval, when the same object enters the sensing range of the first photosensitive device 210 and the second photosensitive device 220 in sequence, there will be a certain time difference in the electrical signal changes detected by the two photosensitive devices.

[0054] For example, in an example, combining Figure 1 As shown, as a user waves their hand from left to right, passing through first photosensitive device 210 and second photosensitive device 220, when the user's hand passes through first photosensitive device 210 at time T0, first photosensitive device 210 detects first signal S0 at time T0. Then, as the user's hand leaves first photosensitive device 210 and passes through second photosensitive device 220 at time T1, second photosensitive device 220 detects second signal S1 at time T1. Based on the time sequence of first signal S0 and second signal S1, the user's gesture can be identified as "swiping from left to right."

[0055] On the contrary, if the user waves from right to left, the time sequence in which the first photosensitive device 210 and the second photosensitive device 220 detect the signals will be opposite, so that the user's gesture action can be identified as "swiping from right to left" based on the signal time sequence.

[0056] Of course, in some embodiments, in addition to the above-mentioned recognition of the gesture waving sequence, the detection signal duration of a single photosensitive device can be further combined to realize the recognition of more gesture actions. The specific process of gesture recognition and control signal input will be explained later in this application and will not be described in detail here.

[0057] From the above, it can be seen that the gesture control component of the embodiment of the present application only needs two photosensitive devices to realize gesture detection and recognition, which is lower in cost than hardware such as cameras, depth sensors, and inertial sensors. In addition, it does not require complex algorithms such as image processing, depth detection, and multi-sensor fusion. Different gestures can be recognized based on the timestamp of the detection signal. The computing power requirement is extremely low, and the requirements can be met by using low-cost control devices, so the cost of the entire machine is lower.

[0058] Continue to refer to Figure 1 As shown, the gesture control component of the present application is further provided with a connector 300 on the shell 100. The function of the connector 300 is to physically connect the gesture control component with the control device. That is to say, the gesture control component can be installed as an extension on any type of control device, thereby expanding the gesture input function of the control device without replacing the existing control device.

[0059] For example, in one example, consider an all-in-one kiosk in a public service facility such as a hospital or bank. Traditional kiosks typically only provide a touchscreen display, requiring users to interact with the kiosk through touch. The gesture control component of the present application, however, can be fixedly mounted on the existing kiosk via a connector 300, extending the kiosk's gesture input functionality and enabling users to input corresponding control commands through gestures.

[0060] For example, in a food store's food delivery control device, traditional devices typically only provide a touch screen display, and staff interact with the control device through touch operations. However, the gesture control component of the present application can be fixedly mounted on the display screen via a connector 300, extending the gesture input function to the display screen, allowing staff to achieve contactless control through gesture operations.

[0061] In the embodiment of the present application, there is no restriction on the fixed connection method between the connector 300 and the control device. For example, snap connection, bolt connection, bonding, magnetic connection, etc. can be used, as long as the connector 300 and the control device can be assembled and connected.

[0062] In addition, taking into account the differences in user operations on different devices and in different scenarios, for example, different devices have differences in height, some devices need to be hung high (such as TVs, display screens, etc.), some devices need to be placed on the ground (such as all-in-one machines, etc.), and some devices need to be placed on the desktop (such as cash registers, etc.). In order to be compatible with different devices, in the gesture control component of the embodiment of the present application, the connector 300 and the shell 100 are connected in an active manner, that is, after the gesture control component is installed on the device, the angle and / or direction of the photosensitive device can be adjusted through the active connection between the connector 300 and the shell 100, thereby adapting to devices in more scenarios.

[0063] For example, in some embodiments, the connector 300 and the housing 100 may be movably connected using a hinge, which allows the two to rotate relative to each other, thereby enabling adjustment of the photosensitive device. For example, in other embodiments, the connector 300 and the housing 100 may be movably connected using a universal joint, which allows the two to rotate relative to each other in three axes, thereby enabling adjustment with more degrees of freedom. For example, in still other embodiments, the connector 300 and the housing 100 may be movably connected using a telescopic rod, which allows the two to move relative to each other, thereby enabling adjustment of the relative distance between them.

[0064] Those skilled in the art will appreciate that the movable connection between the connector 300 and the housing 100 may be achieved in other ways, and is not limited to the above examples, and will not be elaborated in this application.

[0065] In some embodiments, in order to realize signal processing of the photosensitive device, the gesture control component also includes a controller 400. The controller 400 refers to the control core of the gesture control component. The controller 400 is connected to two photosensitive devices, so that it can obtain the electrical signals collected by the two photosensitive devices and generate control signals based on the electrical signals.

[0066] At the same time, the controller 400 can also establish a communicative connection with the control device, so that the controller 400 can send a control signal to the control device to achieve corresponding functional control. For example, in some embodiments, the controller 400 can establish a wireless communication connection with the control device through a wireless communication module (such as Bluetooth, WiFi, etc.). For example, in other embodiments, the controller 400 can establish a wired communication connection with the control device through a wired connection. This application does not limit the communication connection method between the controller 400 and the control device.

[0067] In some embodiments, the controller 400 may be disposed within the housing 100. The controller 400 may include a circuit board, a processor, and a memory disposed on the circuit board. For example, the controller 400 may utilize an STM32 control board in the related art. This is well understood and fully implemented by those skilled in the art, and will not be further elaborated herein.

[0068] From the above, it can be seen that the gesture control component of the embodiment of the present application only needs at least two photosensitive devices to realize gesture detection and recognition. Compared with the hardware cost of cameras, depth sensors, inertial sensors, etc., it is lower than that of hardware such as cameras, depth sensors, and inertial sensors. In addition, it does not require complex algorithms such as image processing, depth detection, and multi-sensor fusion. Different gestures can be recognized based on the timestamp of the detection signal. The computing power requirements are extremely low, and the requirements can be met by using low-cost control components, so the cost of the whole device is lower. Moreover, through the component method, it can be installed as an extension on any type of control device, thereby expanding the gesture input function of the control device without replacing the existing control device, reducing costs. In addition, through the movable connection of the connector, after the gesture control component is installed on the device, the angle and / or direction of the photosensitive device can be adjusted to adapt to devices in more scenarios.

[0069] Figure 2 shows a front structural diagram of a gesture control component in some embodiments, Figure 3 shows a schematic diagram of the structure of the gesture control component and the control device after assembly in some embodiments, Figure 4 The internal structure diagram of the gesture control component in some embodiments is shown below. Figures 1 to 4 The structure and principle of the gesture control component are explained.

[0070] In some embodiments, the housing 100 is a substantially rectangular parallelepiped structure, and one side wall of the housing 100 is defined as a first surface, for example Figure 1 In this example, the front side wall of the housing 100 is defined as the first surface A, wherein the first photosensitive device 210 and the second photosensitive device 220 are spaced apart on the first surface A, and the first photosensitive device 210 and the second photosensitive device 220 are respectively arranged at both ends of the housing 100 along the x-axis direction of the o-xyz coordinate system in the figure. Figure 1 and Figure 4 As shown, the first photosensitive device 210 and the second photosensitive device 220 are installed inside the housing 100, and the directions of their optical axes a and b are perpendicular to the first surface A, so that the first photosensitive device 210 and the second photosensitive device 220 can collect light changes in front of the gesture control component.

[0071] See also Figure 2 As shown, in one example, the first photosensitive device 210 and the second photosensitive device 220 both use diffuse reflection sensors. Taking the first photosensitive device 210 as an example, the diffuse reflection sensor includes a light source 211 and a receiver 212. The light source 211 is used to emit light in the direction of the optical axis. The light emitted by the light source 211 will enter the receiver 212 after being reflected by an object, so that the receiver 212 can receive the reflected light. The receiver 212 is an electrical device made of photosensitive material. When the reflected light changes, the electrical signal generated by the receiver 212 will also change, so that it can be detected whether there is an object within the sensing range. As for the structure and principle of the diffuse reflection sensor, if there are any details not fully described in this article, those skilled in the art can undoubtedly understand it by referring to the relevant technology, and this application will not elaborate on it.

[0072] Continue to refer to Figure 1 、 Figure 2 In some embodiments, the connector 300 and the housing 100 are connected in a hinged manner, and the hinged connection can provide the connector 300 and the housing 100 with the ability to rotate around the x-axis.

[0073] like Figure 1 As shown, the connector 300 includes a connecting plate 310 and a rotating shaft 320. The upper surface of the housing 100 is provided with protruding lugs 121 and 122. The ends of the rotating shaft 320 are respectively mounted on the lugs 121 and 122 and are restrained by bolts to prevent the rotating shaft 320 from being dislodged. The axis c of the rotating shaft 320 is parallel to the first surface of the housing 100, that is, the axis c is parallel to the x-axis, allowing the connecting plate 310 and the housing 100 to rotate about the axis c. When the housing 100 rotates about the axis c, the optical axis directions of the two photosensitive devices change accordingly, thereby achieving angle adjustment.

[0074] like Figure 2As shown, in some embodiments, the connecting plate 310 is provided with connecting holes 311. The number of connecting holes 311 is not limited. When the connecting plate 310 is fixedly assembled with the control device, bolts or screws can be used to secure the connecting plate 310 to the control device through the connecting holes 311. Of course, it will be understood that, as described above, the assembly method here is only one example, and other connection methods can also be used to achieve fixed installation of the connecting plate 310, which will not be described in detail in this application.

[0075] like Figure 3 As shown, in this example, the control device is a display device 500, which can be a tablet computer, a display, etc. Figure 3 In this example, the gesture control component can be fixedly mounted on the display device 500 via the aforementioned connecting plate 310 , and the angle of the gesture control component can be adjusted as needed by rotating the rotating shaft 320 .

[0076] The hardware assembly structure of the gesture control component and the display device 500 is described above. In order to realize the functional connection between the gesture control component and the display device 500, it is also necessary to establish an electrical connection between the controller 400 of the gesture control component and the display device 500.

[0077] As mentioned above, a wireless communication module, such as a Bluetooth, WiFi, or other module, can be provided in the gesture control component to achieve a communicative connection between the controller 400 and the display device 500. However, this method requires the display device 500 to support the wireless communication function. If the display device 500 does not support the wireless communication function, it cannot be implemented. Therefore, the following embodiments of the present application also provide a wired connection communication method. Figure 4 and Figure 5 Provide explanation.

[0078] Figure 4 shows a schematic diagram of the internal structure of the gesture control component in some embodiments, Figure 5 A schematic structural diagram of the back side of a gesture control component in some embodiments is shown.

[0079] like Figure 4 As shown, the controller 400 is disposed inside the housing 100, and the first photosensitive device 210 and the second photosensitive device 220 are electrically connected to the controller 400 via a connecting line. At the same time, the controller 400 establishes a communicative connection with the display device 500 via the connecting line.

[0080] like Figure 5As shown, a cable outlet 131 is provided on the rear side wall of the housing 100, so that the connection cable of the controller 400 passes through the cable outlet 131 and is connected to the display device 500. For example, in one example, the controller 400 can establish a wired communication connection with the display device 500 via a USB (Universal Serial Bus) cable.

[0081] In some embodiments, the controller 400 may adopt, for example, an STM32 control board, which includes a circuit board and related processing components deployed on the circuit board. Those skilled in the art will understand that this disclosure will not elaborate on this.

[0082] In the above example, combined with Figure 3 As shown, after the gesture control assembly is fixedly assembled with the display device 500 via the connector 300 , a communication connection between the controller 400 and the display device 500 can be established via a connecting line.

[0083] In some embodiments, the gesture control component of the present application further includes an indicator light 600, see Figure 1 As shown, a light slot is provided on the first surface of the housing 100, and an indicator light 600 is installed in the light slot. The function of the indicator light 600 is to provide feedback to the user on the recognition result during the gesture detection and recognition process.

[0084] See also Figure 2 As shown, in some embodiments, the indicator light 600 includes a first light strip 610 and a second light strip 620, which are arranged in parallel. The first light strip 610 and the second light strip 620 are both flowing light strips, which are light strips composed of multiple arranged light beads. The flowing light strip can achieve an effect similar to water flow by sequentially flashing the light beads.

[0085] In the example of the present disclosure, the flow directions of the first light strip 610 and the second light strip 620 can be set to be opposite, that is, the flashing directions of the lamp beads of the first light strip 610 and the second light strip 620 are opposite, for example Figure 2 In the example, the flow direction of the first light strip 610 can be set to "from left to right", and the flow direction of the second light strip 620 can be set to "from right to left". Of course, it can also be vice versa, as long as the directions of the two flowing light strips are opposite.

[0086] The purpose of setting the first light strip 610 and the second light strip 620 in opposite directions is to provide the user with different gesture recognition operations through the light flow effects in different directions. The specific methods of gesture and light control will be explained later and will not be detailed here.

[0087] In some embodiments, considering that the distance between the user and the gesture control component may vary in different scenarios, in the embodiment of the present application, the first photosensitive device 210 and the second photosensitive device 220 use sensor devices with adjustable sensing ranges.

[0088] For example, in one example, the first photosensitive device 210 and the second photosensitive device 220 take the aforementioned diffuse reflection sensor as an example. A distance adjustment structure can be provided on the diffuse reflection sensor. The distance adjustment structure can specifically be a screw that can be turned. By turning the screw in different directions, the resistance value and / or light emission power of the internal circuit of the diffuse reflection sensor can be changed, thereby adjusting the sensing range of the sensor.

[0089] In some embodiments, the adjustable sensing range of the first photosensitive device 210 and the second photosensitive device 220 is 10 cm to 200 cm.

[0090] like Figure 5 As shown, in some embodiments, an adjustment hole 160 is opened at a position on the back of the shell 100 corresponding to the first photosensitive device 210 and the second photosensitive device 220. The adjustment hole is opposite to the distance adjustment structure of the photosensitive device. Therefore, a tool can be used to extend into the adjustment hole 160 to adjust the sensing range of the photosensitive device and change the sensing distance of the photosensitive device.

[0091] The above describes the structure of the gesture control component in this application. The following describes its working principle and assembly process.

[0092] Combine Figures 1 to 5 As shown, first, the sensing range of the sensor can be adjusted using adjustment hole 160 to the desired distance based on the specific scenario. Next, the gesture control assembly is fixed to the display device 500 via connecting plate 310. The angle and direction of the sensor can be adjusted by rotating shaft 320 to a position suitable for user operation. Finally, the connection cable of controller 400 can be plugged into the display device 500 to establish an electrical connection.

[0093] After completing the above assembly, the following embodiments of this application provide some examples of gesture control logic, which can be used as a reference by those skilled in the art.

[0094] Reference Figure 2In the direction shown, as a user waves from left to right, the user's hand passes through the first photosensitive device 210 and the second photosensitive device 220 in sequence. When the user's hand passes through the first photosensitive device 210 at time T0, the first photosensitive device 210 detects a first signal S0 at time T0. Then, as the user's hand leaves the first photosensitive device 210 and passes through the second photosensitive device 220 at time T1, the second photosensitive device 220 detects a second signal S1 at time T1. The controller 400 generates a first control instruction C1 based on the control logic of "successively detecting the first signal S0 and the second signal S1 within a preset time (e.g., 1 second). The controller 400 can send the first control instruction C1 to the display device 500, causing the display device 500 to perform the corresponding operation based on the first control instruction C1. At the same time, the controller 400 can control the first light strip 610 to flash, forming a light effect flowing from left to right, to prompt the user that the gesture recognition is successful.

[0095] When a user waves from right to left, their hand passes through the second photosensitive device 220 and then the first photosensitive device 210. When the user's hand passes through the second photosensitive device 220 at time T2, the second photosensitive device 220 detects the third signal S3 at time T2. Then, as the user's hand leaves the second photosensitive device 220 and passes through the first photosensitive device 210 at time T3, the first photosensitive device 210 detects the fourth signal S4 at time T3. The controller 400 generates a second control instruction C2 based on the control logic of "successively detecting the third signal S3 and the fourth signal S4 within a preset time (e.g., 1 second). The controller 400 can send the second control instruction C2 to the display device 500, causing the display device 500 to perform the corresponding operation based on the second control instruction C2. At the same time, the controller 400 can control the second light strip 620 to flash, creating a light effect that flows from right to left, to indicate to the user that the gesture recognition was successful.

[0096] The user can block a single photosensitive device for a long time. For example, the user blocks the first photosensitive device 210 for a long time (such as 2 seconds or more). At this time, the first photosensitive device 210 detects the fifth signal S5, and the controller 400 generates a third control instruction C3 according to the control logic of "detecting the fifth signal S5 for a long time (such as 2 seconds or more)". The controller can send the third control instruction C3 to the display device 500 so that the display device 500 performs the corresponding operation according to the third control instruction C3. At the same time, the controller 400 can control the first light strip 610 to flash continuously two or more times, forming a light effect that flows and flashes from left to right multiple times to prompt the user that the gesture recognition is successful.

[0097] For another example, if a user blocks the second light sensor 220 for a long time (e.g., 2 seconds or longer), the second light sensor 220 detects the sixth signal S6. The controller 400 generates a fourth control instruction C4 based on the control logic of "detecting the sixth signal S6 for a long time (e.g., 2 seconds or longer)." The controller can send the fourth control instruction C4 to the display device 500, causing the display device 500 to perform the corresponding operation according to the fourth control instruction C4. At the same time, the controller 400 can control the second light strip 620 to flash two or more times continuously, forming a multiple-flow flashing light effect from right to left, to prompt the user that the gesture recognition is successful.

[0098] In one example, to avoid misjudgment caused by the sensor being blocked by an obstacle, a fault detection control logic can be further configured. For example, if a photosensitive device is blocked for a long time (e.g., more than 10 seconds), the photosensitive device will detect the seventh signal S7 for a long time. The controller 400 will determine that there is a foreign object blocking the device based on the control logic of "detecting the seventh signal S7 for a long time (e.g., more than 10 seconds)". At this time, the first light strip 610 and the second light strip 620 can be controlled to flash continuously to prompt the user that there is a fault.

[0099] In one example, when it is determined that there is a foreign object blocking the display, the controller 400 may also send a fifth control instruction C5 to the display device 500 to cause the display device 500 to display a fault prompt message or use the speaker of the display device 500 to issue a sound alarm.

[0100] The above describes the working principle and control logic of the gesture control component in the embodiment of the present application. It is understandable that based on the above examples, those skilled in the art can undoubtedly implement more types of gesture control, which cannot be exhaustively listed in this application.

[0101] In the above Figures 1 to 5 Based on the illustrated implementation, the gesture control component of the present application can also be implemented as the following alternatives:

[0102] In some alternative embodiments, the first photosensitive device 210 and the second photosensitive device 220 may be disposed on the housing 100 in a manner other than limited to: Figure 1 The left-right arrangement shown can also be arranged vertically or diagonally. In theory, as long as there is a certain distance between the two, user gesture recognition can be achieved. For example, in one example, the first photosensitive device 210 and the second photosensitive device 220 can be arranged vertically and spaced apart to recognize the user's waving motion from top to bottom or from bottom to top. Those skilled in the art will understand this and will not be elaborated in this application.

[0103] In other alternative embodiments, the number of photosensitive devices included in the gesture control component can be greater, and the arrangement of these photosensitive devices on the gesture control component can also be more diverse. For example, in one example, the gesture control component can include 3 photosensitive devices, and the 3 photosensitive devices can be arranged in a triangle or V shape. For example, in another example, the gesture control component can include 4 photosensitive devices, and the 4 photosensitive devices can be arranged in a rectangle or a cross shape. It is understandable that when a larger number of photosensitive devices are included, the recognition of one or more user gestures can be achieved by using any two photosensitive devices, so that the combination of multiple photosensitive devices can achieve the recognition of a larger number of user gestures.

[0104] In some alternative implementations, the action recognition logic for one or more photosensitive devices is not limited to the above examples. In addition to the unidirectional waving and long-term occlusion in the above examples, multiple (3 or more) photosensitive devices can also be used to implement gesture path recognition, such as using 3 photosensitive devices to recognize L-shaped gestures, V-shaped gestures, etc. Alternatively, by setting different occlusion duration intervals, multiple occlusion actions can be recognized, such as short-term occlusion of the photosensitive device, long-term occlusion of the photosensitive device, etc. This application does not impose any restrictions on this.

[0105] Regarding the above-mentioned alternative implementations, those skilled in the art can undoubtedly understand and fully implement them based on the aforementioned implementations and in combination with relevant technologies, and this application will not elaborate on them.

[0106] In some embodiments, the present application provides an electronic device, such as Figure 3 As shown, the electronic device may include a display device 500 and a gesture control component of any of the above embodiments. The gesture control component can be fixedly assembled with the display device 500 through a connector 300, and the controller 400 establishes a communicative connection with the display device 500 via a wired or wireless manner.

[0107] As can be seen from the above, in the embodiments of the present application, the gesture control component only requires two photosensitive devices to achieve gesture detection and recognition. Compared with hardware costs such as cameras, depth sensors, and inertial sensors, it is lower in cost and does not require complex algorithms such as image processing, depth detection, and multi-sensor fusion. Different gestures can be recognized based on the timestamp of the detection signal. The computing power requirements are extremely low, and low-cost control components can meet the requirements, so the overall cost of the device is lower. Moreover, the component can be installed as an extension on any type of control device, thereby expanding the gesture input function of the control device without replacing the existing control device and reducing costs. In addition, through the movable connection of the connector, after the gesture control component is installed on the device, the angle and / or direction of the photosensitive device can be adjusted, thereby adapting the device to more scenarios. In addition, by setting an indicator light to feedback the user's gesture recognition results, the user experience is improved.

[0108] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the embodiments. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present disclosure.
