Or the user may input the user command by inputting a specific sound or gesture, the user input interface recognizes the sound or gesture through the sensor, and receives the user input command.

In some embodiments, a "user interface" is a media interface for interaction and exchange of information between an application or operating system and a user that enables conversion between an internal form of information and a form acceptable to the user. A commonly used presentation form of a user interface is a graphical user interface (Graphic User Interface, GUI), which refers to a graphically displayed user interface that is related to computer operations. It may be an interface element such as an icon, a window, a control, etc. displayed in a display screen of the electronic device, where the control may include at least one of a visual interface element such as an icon, a button, a menu, a tab, a text box, a dialog box, a status bar, a navigation bar, a Widget, etc.

In some embodiments, the user interface 280 is an interface (e.g., physical keys on a display device body, or the like) that may be used to receive control inputs.

In some embodiments, the display device 200 may be a touch display device, where the display device is a touch display formed by a touch component and a screen. The touch display device supports the touch interaction function, and a user can operate the host only by lightly touching the display with fingers, so that the operations of a keyboard, a mouse and a remote controller are eliminated, and man-machine interaction is more straightforward. On the touch display, the user can input different control instructions through touch operations. For example, a user may input touch instructions such as clicking, sliding, long pressing, double clicking, etc., and different touch instructions may represent different control functions.

To achieve the different touch actions described above, the touch sensitive assembly may generate different electrical signals when the user inputs the different touch actions, and transmit the generated electrical signals to the controller 250. The controller 250 may perform feature extraction on the received electrical signal to determine a control function to be performed by the user based on the extracted features. For example, when a user enters a click touch action at any program icon location in the application program interface, the touch component will sense the touch action and thereby generate an electrical signal. After receiving the electrical signal, the controller 250 may determine the duration of the level corresponding to the touch action in the electrical signal, and recognize that the user inputs the click command when the duration is less than the preset time threshold. The controller 250 then extracts the location features generated by the electrical signals to determine the touch location. When the touch position is within the application icon display range, it is determined that a click touch instruction is input by the user at the application icon position. Accordingly, the click touch instruction is used to perform a function of running a corresponding application program in the current scenario, and thus the controller 250 may start running the corresponding application program.

For another example, when the user inputs a sliding motion in the media presentation page, the touch assembly also sends the sensed electrical signal to the controller 250. The controller 250 first determines the duration of the signal corresponding to the touch action in the electrical signal. When the duration time is determined to be longer than the preset time threshold value, the position change condition generated by the signals is judged, and obviously, the generation position of the signals changes for the interactive touch action, so that the user is determined to input a sliding touch instruction. The controller 250 then determines the sliding direction of the sliding touch command according to the change condition of the signal generating position, and controls the page turning of the display screen in the media display page so as to display more media options. Further, the controller 250 may further extract characteristics such as a sliding speed and a sliding distance of the sliding touch instruction, and perform a picture control of turning pages according to the extracted characteristics, so as to achieve a following effect.

Similarly, for the touch instructions such as double-click and long-press, the controller 250 may extract different features, determine the type of the touch instruction through feature judgment, and execute corresponding control functions according to a preset interaction rule. In some embodiments, the touch component 276 also supports multi-touch so that a user can enter touch actions on the touch screen via multiple fingers, e.g., multi-finger clicks, multi-finger long presses, multi-finger swipes, etc.

The touch control action can be matched with a specific application program to realize a specific function. For example, after the user opens the "demonstration whiteboard" application, the display 260 may present a drawing area, the user may draw a specific touch action track in the drawing area through the sliding touch command, and the controller 250 determines a touch action pattern through the touch action detected by the touch component and controls the display 260 to display in real time, so as to satisfy the demonstration effect. For example, it is a basic function of a touch screen display device that a user rotates a finger touching a display to control the display to display a picture. The current interaction mode is that after a plurality of fingers rotate on a screen, the picture immediately rotates to a horizontal or vertical angle according to the rotation direction of the fingers, no interaction process exists, and the user experience is poor.

In some embodiments, a system of display devices may include a Kernel (Kernel), a command parser (shell), a file system, and an application program. The kernel, shell, and file system together form the basic operating system architecture that allows users to manage files, run programs, and use the system. After power-up, the kernel is started, the kernel space is activated, hardware is abstracted, hardware parameters are initialized, virtual memory, a scheduler, signal and inter-process communication (IPC) are operated and maintained. After the kernel is started, shell and user application programs are loaded again. The application program is compiled into machine code after being started to form a process.

Referring to FIG. 4, in some embodiments, the system is divided into four layers, from top to bottom, an application layer (referred to as an "application layer"), an application framework layer (Application Framework) layer (referred to as a "framework layer"), a An Zhuoyun row layer (Android runtime) and a system library layer (referred to as a "system runtime layer"), and a kernel layer, respectively.

In some embodiments, at least one application program is running in the application program layer, and these application programs may be a Window (Window) program of an operating system, a system setting program, a clock program, or the like; or may be an application developed by a third party developer. In particular implementations, the application packages in the application layer are not limited to the above examples.

The framework layer provides an application programming interface (application programming interface, API) and programming framework for the application programs of the application layer. The application framework layer includes a number of predefined functions. The application framework layer corresponds to a processing center that decides to let the applications in the application layer act. Through the API interface, the application program can access the resources in the system and acquire the services of the system in the execution.

As shown in fig. 4, the application framework layer in the embodiment of the present application includes a manager (Managers), a Content Provider (Content Provider), and the like, where the manager includes at least one of the following modules: an activity manager (ACTIVITY MANAGER) is used to interact with all activities running in the system; a Location Manager (Location Manager) is used to provide system services or applications with access to system Location services; a package manager (PACKAGE MANAGER) for retrieving various information about the application packages currently installed on the device; a notification manager (Notification Manager) for controlling the display and clearing of notification messages; a Window Manager (Window Manager) is used to manage bracketing icons, windows, toolbars, wallpaper, and desktop components on the user interface.

In some embodiments, the activity manager is used to manage the lifecycle of the individual applications as well as the usual navigation rollback functions, such as controlling the exit, opening, fallback, etc. of the applications. The window manager is used for managing all window programs, such as obtaining the size of the display screen, judging whether a status bar exists or not, locking the screen, intercepting the screen, controlling the change of the display window (for example, reducing the display window to display, dithering display, distorting display, etc.), etc.

In some embodiments, the system runtime layer provides support for the upper layer, the framework layer, and when the framework layer is in use, the android operating system runs the C/C++ libraries contained in the system runtime layer to implement the functions to be implemented by the framework layer.

In some embodiments, the kernel layer is a layer between hardware and software. As shown in fig. 4, the kernel layer contains at least one of the following drivers: audio drive, display drive, bluetooth drive, camera drive, WIFI drive, USB drive, HDMI drive, sensor drive (e.g., fingerprint sensor, temperature sensor, pressure sensor, etc.), and power supply drive, etc.

Based on the display device, the display device can support the rotation and/or lifting functions by adding the driving component and the gesture detection component. Typically, the drive assembly includes a rotation assembly and/or a lift assembly with which the controller 250 may communicate to control the rotation assembly to drive the display to rotate when it is desired to rotate the display and to control the lift assembly to drive the display to raise or lower when it is desired to raise or lower the display.

In a possible implementation manner, the rotating component and/or the lifting component are provided with a GPIO interface, and the controller changes the GPIO interface state of the rotating component and/or the lifting component by reading the GPIO interface. When the state of the GPIO interface is changed, the rotating component and/or the lifting component drive the display to rotate and/or lift according to the changed state of the GPIO interface.

In a possible implementation, the lifting assembly and/or lifting assembly includes an MCU chip on which a bluetooth module is integrated, such that the lifting assembly and/or lifting assembly supports bluetooth functions, such as Bluetooth Low Energy (BLE), and further, the controller 250 may communicate with the lifting assembly and/or lifting assembly based on a bluetooth protocol.

In some embodiments, the detection assembly includes a sensor for detecting a rotational state of the display and a sensor for detecting a display lift state. During the rotation or lifting process of the display, the controller monitors the rotation state or lifting state of the display in real time according to the data detected by the gesture detection assembly. For example, in the process of controlling the rotation of the display, information such as the rotation angle, the angle speed and the like is acquired by monitoring the data of the sensor. In the process of controlling the lifting of the display, the information such as the lifting distance, the lifting speed and the like is obtained by monitoring the data of the sensor.

In some embodiments, the detection assembly is included in the drive assembly. For example, a sensor for detecting the rotational state of the display is included in the rotating assembly, and constitutes the rotating assembly together with the rotating assembly. The sensor for detecting the display lifting state is included in the lifting assembly and forms the lifting assembly together with the lifting assembly.

In some embodiments, the rotating assembly is referred to as a rotary drive device and the lifting assembly is referred to as a lifting drive device.

Fig. 5 is a schematic rear view of a display device according to the present application, which includes a display 260 and a lift driving device 511, as shown in fig. 5, in some exemplary embodiments. The lift driving device 511 and the lift rail 512 are fixed to the bracket 512. The rotation driving device is then arranged inside the lifting driving device, i.e. between the lifting driving device and the display, not shown in fig. 5.

In some embodiments, a rotational lift control system is deployed in the operating system of the display device, which may be deployed at the application framework layer, or may be deployed cross-layer, for example, with a portion of the functional code deployed at the application framework layer and another portion of the functional code deployed at the runtime layer. The rotational lift control system may communicate with the drive assembly and the detection assembly to uniformly, cooperatively, and safely control the rotation and lift of the display device.

In specific implementation, through the rotation lifting control system, the same control interface provided for each application comprises only control inlets such as clockwise rotation, anticlockwise rotation, stop rotation, short-distance lifting, long-distance lifting and stop lifting, and the like, so that lifting operation and rotation operation are prevented from being performed simultaneously, and the safety of rotation lifting control is ensured. In addition, the rotation lifting control system performs unified logic processing and judgment on control instructions issued by each application. For example, before controlling rotation, it is necessary to determine whether the rotation is in the process of lifting or lowering, and if not, the rotation is controlled again. When the rotation starts, each application is notified through broadcasting, and the application is guaranteed to receive the same notification information. In the process of controlling rotation, the monitoring sensor detects big data to acquire information such as rotation angle, angular speed and the like and update parameters, and the parameter information can be fed back to each application. The system performs a rotation end detection every preset time (e.g., 200 ms), and when the rotation is ended, sends a broadcast notification application.

In some embodiments, the controller 250 turns on the bluetooth module in response to a bluetooth switch turn-on instruction. And scanning the lifting driving device and/or the rotating lifting device according to preset device identifiers through the Bluetooth module, wherein the preset device identifiers can be device names or universal unique identifier codes UUIDs of the lifting driving device and the rotating lifting device. When a plurality of lifting driving devices are scanned according to preset device identifiers, determining a target lifting driving device according to the signal intensity of each lifting driving device; when only one lift driving device is scanned according to the preset device identification, the one lift driving device is determined as the target lift driving device. When a plurality of rotary driving devices are scanned according to preset device identification, determining a target rotary driving device according to the signal intensity of each rotary driving device; when only one rotation driving device is scanned according to the preset device identification, the one rotation driving device is determined as the target rotation driving device.

After the target rotation driving device or the target lifting driving device is determined, communication connection is established with the target rotation driving device or the target lifting driving device, so that when the display lifting needs to be controlled, the target lifting driving device is controlled to drive the display to lift based on the communication connection with the target lifting driving device, and when the display rotation needs to be controlled, the target rotation driving device is controlled to drive the display to rotate based on the communication connection with the target rotation driving device. In this way, when a plurality of lifting driving devices or rotating driving devices with the same type and/or the same identification exist in the environment where the display device is located, driving devices matched with the display device can be screened from the plurality of devices according to the signal intensity of each device, so that the display device is prevented from being connected to other driving devices. The driving device matched with the display device refers to a driving device matched with the mechanical structure of the display device or a driving device mechanically connected with the display device.

For example, fig. 6 is an application scenario, which may be a simple illustration of a mall in particular, of the present application, shown in some exemplary embodiments. As shown in fig. 6, in this scenario, there are a plurality of smart televisions having a lifting function, each of which is equipped with at least one lifting driving device for driving the screen of the smart television to lift. It should be appreciated that in this scenario, the lifting drive device that is powered on and not connected to the smart tv will continuously send bluetooth broadcast information to the outside, so that the smart tv can discover itself after turning on scanning. In such an implementation scenario, after the bluetooth module of a certain smart television starts scanning, a plurality of lifting driving devices with the same type and/or identification can be scanned, wherein the lifting driving devices comprise lifting driving devices matched with the smart television and lifting driving devices matched with other smart televisions in the environment. As can be seen from the above-described embodiments, in this case, the smart tv determines the target lift driving device according to the signal intensity of each lift driving device and establishes a communication connection with the target lift driving device, so that it is possible to avoid connection to an erroneous lift driving device.

In addition, if the user changes the lifting driving device or the rotating driving device of the display device, after the change is completed, the Bluetooth switch of the display device is closed and opened again, and then the pairing and connection flow of the new lifting driving device or the new rotating driving device can be triggered.

In some embodiments, when the controller detects that the bluetooth switch is turned on, a scan instruction is sent to the bluetooth module, where the scan instruction includes a preset device identifier. After receiving the scanning instruction, the Bluetooth module starts scanning. It should be understood that after the bluetooth module starts scanning, bluetooth broadcast information sent by the external device may be received, where the bluetooth broadcast information includes data such as a device identifier, a signal strength RSSI (RECEIVED SIGNAL STRENGTH Indication) value, and the like. The Bluetooth module matches the equipment identifier of the external equipment with the preset equipment identifier, determines the external equipment with the equipment identifier matched with the first preset equipment identifier as lifting driving equipment, and determines the external equipment with the equipment identifier matched with the second preset equipment identifier as rotation driving equipment. Wherein the device identification matches a preset device identification, including but not limited to the same case as the preset device identification. Thus, the display device can filter other external devices according to the preset device identification, and only the scanning result of the lifting driving device or the rotating driving device is reserved.

In some embodiments, when the bluetooth module scans a plurality of lift drive devices according to the first preset device identification, a target lift drive device is determined according to the signal strength of each lift drive device. And when the Bluetooth module scans a plurality of rotary driving devices according to the second preset device identification, determining a target rotary driving device according to the signal intensity of each rotary driving device.

In one possible implementation, the lift drive device with the highest signal strength is determined as the target lift drive device. For example, the signal strength of the lift drive device may be evaluated based on the average level of the RSSI values of the lift drive device over a period of time, and the signal strength of the rotation drive device may be evaluated based on the average level of the RSSI values of the rotation drive device over a period of time. For example, if the bluetooth module scans a plurality of lifting driving devices according to a preset device identifier, the bluetooth module continues scanning, so as to obtain preset several RSSI values of each lifting driving device by continuously receiving bluetooth broadcast information sent by the plurality of lifting driving devices. After a preset number of RSSI values are obtained for each lifting driving device, the Bluetooth module closes scanning, and feeds back the scanned device information of each lifting driving device and the preset number of RSSI values of each lifting driving device to the controller. And the controller calculates the RSSI average value of each lifting driving device according to a preset plurality of RSSI values of each lifting driving device, and determines the lifting driving device with the largest RSSI average value as the target lifting driving device.

In some embodiments, bluetooth Low Energy (BLE) connections are established over the GATT protocol, with the display device in communication with the rotary drive device and/or the lift drive device based on the GATT. GATT, collectively referred to as Generic Attribute Profile, can be translated into a "common Attribute protocol" which refers to a general specification over bluetooth connections for transmitting and receiving very short data segments, referred to as attributes (attributes). GATT defines that two BLE devices communicate through a Service (Service) and a feature value (challenge). The characteristic value of the characteristic may be understood as a tag, and the desired content may be obtained or written by the tag. In the BLE slaves deployed by Service, each Service represents a capability of the BLE slaves, such as a power information Service, a system information Service, and the like, each Service contains a plurality of characteristic feature values, and each specific characteristic feature value is a subject of BLE communication. For example, the current electric quantity is 80%, and the characteristic value of the current lighting passing electric quantity exists in the profile of the slave machine, so that the host machine can read that the current electric quantity is 80% through the characteristic value CHARACTERISTICC of the electric quantity.

It should be noted that, in the GATT protocol, both the Service (Service) and the feature value (characacteristic) of the BLE slave device need to be identified by the universal unique identification code UUID of the BLE slave device, so that if the two BLE devices are to establish a GATT connection, the BLE slave device needs to open the UUID Service. Based on this, in the process of scanning the rotation driving device and/or the lifting driving device, after determining that the scanned external device is the rotation driving device or the lifting driving device, it is further required to determine whether each rotation driving device or lifting driving device opens UUID service, so as to filter out the rotation driving device or lifting driving device that does not open UUID service, so as to determine the target driving device from the rotation driving device or lifting driving device that opens UUID service.

In some embodiments, after determining the target drive device, the controller 250 establishes a GATT communication connection with the target drive device to control the target drive device to drive the display up and down based on the GATT communication connection. In a specific implementation, the controller 250 first performs pairing with the target driving device, and if the pairing is successful, establishes GATT communication connection with the target driving device based on a GATT procedure. If the pairing is failed or the GATT communication connection is failed, scanning the rotation driving device or the lifting driving device according to the preset device identification again, and executing the follow-up steps according to the scanning result.

The rotation lifting control system is used as a GATT client, and the rotation driving device and the lifting driving device are used as GATT servers. When the switch of the Bluetooth module of the display device is turned on, the lifting control system performs Bluetooth pairing with the rotary driving device and the lifting driving device, and establishes GATT communication connection with the rotary driving device and the lifting driving device after the Bluetooth pairing is successful. After connection is successful, the rotary lifting control system is used as a GATT client, information such as the state, the position and the faults of the rotary driving equipment and the lifting driving equipment serving as a GATT server can be queried at regular time, and meanwhile, when the rotary driving equipment or the lifting driving equipment fails or lifts to a limit switch, the state can be actively fed back to the rotary lifting control system, so that each application is guaranteed to read the latest lifting state.

It should be noted that, in the GATT protocol-based network topology, one BLE master (also referred to as a central device) may be connected to a plurality of BLE slaves (also referred to as peripheral devices), and one BLE slave may be connected to only one BLE master. It should be understood that, in the present application, after the display device establishes GATT communication connection with the target driving device, the display device is a BLE master device, and the target driving device is a BLE slave device. When the target driving device is successfully connected with the display device, the Bluetooth broadcasting information is stopped from being sent to the outside.

It should be noted that, both sides based on GATT communication are C/S relationships, where the peripheral device is defined as a GATT server, and service and communication are defined. The central device acts as a GATT client, which initiates a request to the server. It should be noted that all communication events are initiated by the client and are implemented by receiving a response from the server. It should be understood that, in the present application, after the display device establishes GATT communication connection with the target driving device, the display device is used as a GATT client to initiate a request to the server, for example, a request for periodically querying information such as a rotation lifting state, a position, a fault and the like of the target driving device; and the target driving device serves as a GATT server and returns a response to the client.

As can be seen from the above embodiments, according to the display device provided by the embodiment of the present application, when a plurality of rotation driving devices and lifting driving devices with the same type and/or the same identifier exist in an environment where the display device is located, a target rotation driving device and a target lifting driving device matched with the display device can be selected from the plurality of rotation driving devices and lifting driving devices according to signal intensities of the rotation driving devices and the lifting driving devices, so that the display device is prevented from being connected to other driving devices. In addition, if the user changes the rotation driving device or the lifting driving device of the display device, after the change is completed, the Bluetooth switch of the display device is turned off and turned on again, and the pairing and connection flow of the new rotation driving device or the lifting driving device can be triggered.

In some embodiments, a user may control the display to rotate or lift by operating a remote control, opening a system setup application, and accessing an interface operable to rotate and lift the display, and thus by operating a corresponding item in the interface.

For the touch display device, in order to save user operations, a user can more conveniently operate the display to rotate and lift, and the user can also input a user gesture by touching the touch display, and if the input user gesture is a predetermined gesture for controlling rotation or lift, the controller 250 controls the rotation driving device or the lift driving device to drive the display to rotate or lift.

In some embodiments, the controller 250 is configured to: an input user gesture is received. Whether the user gesture corresponds to a predetermined gesture is determined. If the user gesture is a preset rotation gesture, controlling a rotation driving device according to the user gesture so as to drive a display to rotate through the rotation driving device; if the user gesture is a preset lifting gesture, the lifting driving device is controlled according to the user gesture so as to drive the display to ascend or descend through the lifting driving device.

It should be understood that in the above embodiments, the user gesture refers to a contact track of the user with the display screen. The controller 250 determines whether the input user gesture is a predetermined rotation gesture or a predetermined lifting gesture by matching the characteristics of the contact trajectory with the characteristics corresponding to the predetermined rotation gesture and the predetermined lifting gesture. The matching process is the process of recognizing the gesture of the user.

In some embodiments, the user must input a predetermined trigger gesture if he or she wants to input a predetermined rotation gesture or a predetermined lift gesture. In the process of recognizing the user gesture, if the preset trigger gesture is recognized, displaying a preset picture on the top layer of the user interface, and taking the preset picture as a mask, wherein the graphical interactive object in the user interface prevents the user from touching the graphical interactive object in the user interface in the process of inputting the preset rotation gesture or the preset lifting gesture to cause false triggering. Under the condition that the preset picture is displayed, continuously identifying a contact track input subsequently, and if the complete contact track does not correspond to a preset rotation gesture or a preset lifting gesture, withdrawing the preset picture so as to restore to the original user interface; and if the complete contact track corresponds to a preset rotation gesture or a preset lifting gesture, the preset picture is withdrawn when the contact disconnection of the user and the display is detected, so that the original user interface is restored.

In some embodiments, if the multi-finger continuous contact is identified and the duration exceeds a third preset time, the identification of the predetermined trigger gesture is confirmed. Illustratively, when the user' S five fingers are detected to be simultaneously in contact with the touch display and for more than 2S, receipt of the predetermined trigger gesture is confirmed.

In some embodiments, if the input user gesture includes a single-finger continuous fixed contact and a multi-finger arc sliding contact that are synchronized to input, the user gesture is determined to be a predetermined rotation gesture.

For example, as shown in fig. 7, the user may simultaneously touch five fingers at any position of the screen, with the thumb held stationary, and the other four fingers slid in a clockwise or counterclockwise arc with reference to the thumb, to input a predetermined rotation gesture. In this example, the thumb is in contact with a single-finger continuous fixed contact, the other four fingers are in contact with a multi-finger arc sliding contact, and the single-finger continuous fixed contact and the multi-finger scribing sliding contact are synchronously input because the five fingers are always in contact with the screen at the same time.

FIG. 8 is a schematic diagram of a user contact trajectory in some exemplary embodiments of the application. Wherein A1, A2, A3, A4 and A5 are respectively initial contacts of five-finger contact, and B1, B2, B3, B4 and B5 are respectively disconnection points of the five-finger contact. A1 and B1 are coincident, namely single-point continuous contact. The arcs formed by connecting A2 with B2, A3 with B3, A4 with B4, A5 with B5 are arc contact tracks corresponding to sliding of other four fingers respectively, the starting point of each contact track is a corresponding initial contact point, and the end point is a corresponding disconnection point. The four contact tracks enclose a single point contact point A1 (B1). In connection with fig. 8, the display device receives a user gesture by detecting a contact trajectory of a user with a screen contact. If a single point contact and four arc contact trajectories around the point of contact of the single point contact are detected simultaneously, the user gesture is determined to be a predetermined rotation gesture.

It should be appreciated that the user may also touch the thumb, index finger and middle finger simultaneously at any location on the screen, the thumb remaining stationary and the other two fingers sliding in a clockwise or counterclockwise arc with reference to the thumb to input a predetermined rotation gesture. In this example, the thumb is in contact with a single-finger continuous stationary contact, and the other two fingers are in contact with a multi-finger arc sliding contact, the single-finger continuous stationary contact being input in synchronism with the multi-finger arc sliding contact. The user may also use other fingers instead of the thumb to input a single finger for constant fixed contact.

In other embodiments, if the input contact is a single point continuous fixed contact and a multi-finger arc sliding contact of the synchronous input, and the angle corresponding to the multi-finger arc sliding contact is greater than a preset angle, the contact is determined to correspond to a predetermined rotation gesture. It is noted that the criterion of the magnitude relation between the angle corresponding to the sliding contact of the multi-finger arc and the preset angle can be preset according to the requirement. For example, if the angle corresponding to the sliding contact of any one arc is larger than the preset angle, it is determined that the angle corresponding to the sliding contact of the multi-finger arc is larger than the preset angle. Or if the angle corresponding to the sliding contact of each arc is larger than the preset angle, determining that the angle corresponding to the sliding contact of the multi-finger arc is larger than the preset angle.

For example, in the example shown in fig. 7, if the angle of rotation of the other four fingers clockwise or counterclockwise with reference to the thumb exceeds the preset angle, the input contact corresponds to a predetermined rotation gesture.

FIG. 9 is a schematic diagram of a user contact trajectory in some exemplary embodiments of the application. Wherein C1, C2, C3, C4 and C5 are respectively initial contacts of five-finger contact, and D1, D2, D3, D4 and D5 are respectively disconnection points of the five-finger contact. C1 and D1 are coincident, namely single-point continuous contact. The arcs formed by connecting C2 and D2, C3 and D3, C4 and D4, and C5 and D5 are arc contact tracks corresponding to other four fingers respectively, the starting point of each contact track is a corresponding initial contact point, and the end point is a corresponding disconnection point. The four contact tracks enclose a single point contact point C1 (D1). The included angle 1 between C1C2 and D1D2 is the sliding angle of the index finger, the included angle 2 between C1C3 and D1D3 is the sliding angle of the middle finger, the included angle 3 between C1C4 and D1D4 is the sliding angle of the ring finger, and the included angle 4 between C1C5 and D1D5 is the sliding angle of the little finger. In connection with fig. 9, the display device receives a user gesture by detecting a contact trajectory of a user with a screen contact. And if the single-point contact and four contact tracks surrounding the contact point of the single-point contact are detected at the same time, and the corresponding angle of each contact track is larger than a preset angle, determining the gesture of the user as a preset rotation gesture. In some embodiments, if the input contact corresponds to a predetermined rotation gesture, the rotation driving device is controlled to drive the display to rotate 90 ° in the direction of the multi-fingered arc sliding. The direction of the multi-finger arc sliding is the direction from the start point to the end point of the contact track. In the example shown in fig. 8, the direction from the start point to the end point is clockwise, which is determined according to any one of the contact tracks. In the example shown in fig. 9, the direction from the start point to the end point is counterclockwise, which is determined according to any one of the contact tracks.

In a specific implementation manner, an application layer recognizes an input user gesture, and when a preset rotation gesture is recognized and the sliding direction of the input multi-finger arc sliding is clockwise, a clockwise rotation instruction is sent to a rotation lifting control system; and when the preset rotation gesture is recognized and the sliding direction of the input multi-finger arc sliding is a counterclockwise direction, sending a counterclockwise rotation instruction to the rotation lifting control system. After receiving the clockwise rotation instruction or the anticlockwise rotation instruction, the rotary lifting control system judges whether the lifting driving equipment is in a working state, if the lifting driving equipment is not in the working state, the rotary lifting control system sends the clockwise rotation instruction or the anticlockwise rotation instruction to the rotary driving equipment, and if the lifting driving equipment is in the working state, after the lifting driving equipment stops, the rotary lifting control system sends the clockwise rotation instruction or the anticlockwise rotation instruction to the rotary driving equipment. The rotary drive device will control the display to rotate 90 deg. clockwise in response to a clockwise rotation command and to rotate 90 deg. counterclockwise in response to a counterclockwise rotation command.

In some embodiments, in order to control the rotation of the display according to the complete contact track, when the contact of the user with the touch display is detected to be disconnected under the condition that a preset rotation gesture is recognized, the rotation of the display is controlled according to the input contact.

For example, referring to fig. 7, if the user touches the five fingers simultaneously to the display and holds the thumb still while in the landscape orientation at the display, the other four fingers rotate clockwise by more than 30 ° with reference to the thumb and lift the five fingers, and the display will rotate 90 ° along the clockwise pointer under the drive of the rotation driving device to assume the portrait orientation shown in fig. 10. Referring to fig. 10, if the user simultaneously touches the five fingers and holds the thumb still while the display is in the portrait posture, the other four fingers rotate counterclockwise by more than 30 ° with reference to the thumb and lift the five fingers, and the display is rotated by 90 ° along the reverse finger by the driving of the rotation driving device to return to the landscape posture shown in fig. 7.

In some embodiments, if the contact trajectory corresponding to the input user gesture is a multi-finger linear sliding contact and the direction of the multi-finger sliding contact matches the vertical direction, then it is determined that the contact corresponds to the predetermined lift gesture.

For example, as shown in fig. 11, the user may touch five fingers at any position of the screen while sliding up or down to input a predetermined lifting gesture.

FIG. 12 is a schematic view of a user contact trajectory in some exemplary embodiments of the application. Wherein E1, E2, E3, E4 and E5 are respectively initial contacts of five-finger contact, and F1, F2, F3, F4 and F5 are respectively disconnection points of the five-finger contact. The connecting lines between E1 and F1, E2 and F2, E3 and F3, E4 and F4, E5 and F5 are respectively straight-line contact tracks corresponding to five fingers, the starting point of each contact track is a corresponding initial contact point, and the end point is a corresponding disconnection point. The direction of each contact trace matches the vertical direction. In connection with fig. 12, the display device receives a user gesture by detecting a contact trajectory of a user with a screen contact. And if five straight contact tracks matched with the vertical direction are detected at the same time, determining that the gesture of the user is a preset rotation gesture.

It should be appreciated that the user may also touch any position of the screen with three or four fingers while sliding up or down to enter a predetermined lift gesture.

In other embodiments, if the contact track corresponding to the user gesture is multi-finger linear sliding contact and the contact duration is greater than the first preset time, it is determined that the user gesture corresponds to the predetermined lifting gesture. For example, in the example shown in fig. 11, when the user touches the five fingers at any position of the screen while sliding up or down, and the contact duration exceeds a first preset time, the user gesture is determined to be a predetermined lift gesture.

In other embodiments, if the input user gesture is a continuous input multi-finger linear sliding contact and a multi-finger continuous fixed contact, wherein the contact point of the multi-finger continuous contact is a sliding termination point of the multi-finger linear sliding, and the duration of the multi-finger continuous fixed contact is greater than a second preset time, the contact is determined to correspond to the predetermined lifting gesture. For example, in the example shown in fig. 11, when the user touches the five fingers at an arbitrary position of the screen while sliding up or down, and after the sliding is terminated, the user gesture is determined to be a predetermined lifting gesture by staying at the sliding termination point for more than a second preset time.

In some embodiments, if the user gesture corresponds to a predetermined lift gesture, the lift driving device is controlled according to the user gesture to drive the display up or down by the lift driving device.

In a specific implementation manner, an application layer recognizes an input user gesture, and when a preset lifting gesture is recognized and the sliding direction of the input multi-finger linear sliding is matched with the upward direction, a lifting instruction is sent to a rotary lifting control system; and when the preset lifting gesture is recognized and the sliding direction of the input multi-finger linear sliding is matched with the downward direction, sending a descending instruction to the rotary lifting control system. After receiving the ascending instruction or the descending instruction, the rotary lifting control system judges whether the rotary driving equipment is in a working state, if the rotary driving equipment is not in the working state, the ascending instruction or the descending instruction is sent to the lifting driving equipment, and if the rotary driving equipment is in the working state, the ascending instruction or the descending instruction is sent to the lifting driving equipment after the rotary driving equipment is stopped. The lifting driving device will drive the display up in response to the up command and drive the display down in response to the down command.

The sliding direction matches with the upward direction, which means that the component of the sliding direction in the vertical direction is upward; the sliding direction matches the downward direction, meaning that the component of the sliding direction in the vertical direction is downward.

In some embodiments, in order to control the display to lift according to the complete contact track, when a predetermined lifting gesture is recognized, the display is lifted according to the control when the contact between the user and the touch display is detected to be disconnected.

In some embodiments, the user may control the display to be lifted long or short by adjusting the sliding distance of the multi-finger linear sliding contact. In particular, the correspondence between the sliding distance and the lifting distance may be established in advance. Further, the lifting distance corresponding to the sliding distance may be determined according to the preset correspondence. Optionally, in the preset corresponding relationship, the larger the sliding distance is, the larger the corresponding lifting distance is.

For example, if the sliding distance of the multi-finger linear sliding contact is greater than a preset distance (e.g., 15 cm), the lifting assembly is controlled to drive the display to rise or fall by a first distance. And if the sliding distance of the multi-finger linear sliding contact is not greater than the preset distance, controlling the lifting assembly to drive the display to ascend or descend by a second distance, wherein the second distance is smaller than the first distance.

It is noted that the criterion of the magnitude relation between the sliding distance and the preset distance may be preset according to the requirement. For example, if the sliding distance of any one of the linear sliding contacts is greater than the preset distance, it is determined that the sliding distance of the multi-finger linear sliding contact is greater than the preset distance. Or if the sliding distance of the linear sliding contact is greater than the preset distance, determining that the sliding distance of the multi-finger linear sliding contact is greater than the preset distance.

Referring to fig. 12, the distances between E1 and F1, E2 and F2, E3 and F3, E4 and F4, and E5 and F5 are respectively the sliding distances of the respective linear sliding contacts. Illustratively, if the user simultaneously touches the five fingers to the display and slides up for 10cm while the display is at the first height shown in fig. 11, and lifts up after resting for more than 10S after the sliding is terminated or lifts up after the contact time with the display exceeds 10S, the display will rise by 50mm under the driving of the lifting assembly, thereby assuming the second height shown in fig. 13, the second height=the first height+50mm. If the user simultaneously touches the five fingers to the display and slides down for 20cm while the display is at the second height shown in fig. 13 and lifts up after resting for more than 10S after the end of the sliding or after the contact time with the display exceeds 10S, the display will descend by 200mm driven by the elevating assembly, thereby assuming the third height shown in fig. 14, the third height=the second height-200 mm. In this example, the preset distance is 15cm, the first distance is 200mm and the second distance is 50mm.

According to the display device provided by the embodiment of the application, the user can control the rotation or lifting of the display by inputting the preset gesture for controlling the rotation or lifting of the display, so that the user can more conveniently operate the rotation and lifting of the display, the user operation is saved, and the user experience is improved.

It should be noted that the user gestures include a touch gesture collected based on the touch sensitive component and a space gesture collected by a user image collected by the camera. Based on the idea of controlling the rotation and/or the lifting of the display device through the touch gesture in the embodiment of the application, a person skilled in the art can obtain the technical scheme of controlling the rotation and/or the lifting of the display device through the space-apart gesture without creative labor.
