Detailed Description
In order to facilitate an understanding of the present application, a more complete description of the present application will now be provided with reference to the relevant figures. Preferred embodiments of the present application are shown in the accompanying drawings. This application may, however, be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
In the related art, a user cannot conveniently control a spliced large screen or a distributed screen in a mode of screen touch, gesture and the like.
Based on this, the present application intends to provide a solution to the above technical problem, the details of which will be explained in the following embodiments.
Examples:
the present embodiment provides a screen control method, which is applied to a control terminal, where the control terminal has a control relationship with at least two screens, and referring to fig. 1, the screen control method of the present embodiment includes:
s101, acquiring user input information sent by at least one screen in the controlled screens;
s102, determining at least one display instruction according to user input information;
each display instruction corresponds to at least one screen in the screens with control relation of the control terminal;
s103, sending a display instruction to a target screen so that the target screen performs display control according to the display instruction.
The control terminal and the screen have a control relationship, namely the control terminal can send a display instruction to the screen, so that the screen can perform display control according to the display instruction. In this embodiment, the control terminal may have a control relationship with any number of screens, but each screen may be independent, or may be a relationship of cooperative work, or may be a relationship of synchronous work. It can be understood that independent screens can respectively display the content which is not related to each other, and the displayed content is not influenced by other screens; the screens of the collaborative work jointly display related content, such as a large screen formed by splicing a plurality of screens, and each screen on the large screen respectively displays a part of the complete content, so that the large screen can completely display the content to be displayed; the synchronously operated screens simultaneously display the same content. In some examples, the screens controlled by the control terminals may be partially independent, one part is in a cooperative working relationship, and the other part may work synchronously, that is, the embodiment does not limit that only one working relationship exists between the screens controlled by the control terminals, and under the condition that the processing capability of the control terminals is enough, various working relationships may coexist.
The control terminal can be used as a single device and arranged outside each screen, for example, in a distributed screen, the control terminal can be arranged at a relatively central position of each screen; or as a sub-device, to a certain screen or a certain part of a screen, for example, in a spliced screen, the control terminal can be set to a certain main control screen.
According to the screen control method, the control terminal determines the display instruction according to the user input information sent by the screen controlled by the control terminal, and sends the display instruction to the corresponding screen to realize display control, so that the user can effectively control the multi-screen display scene such as the spliced large-scale screen or the distributed screen without inputting to the control terminal.
In some embodiments, as shown in fig. 2, determining at least one display instruction according to the user input information includes:
s1021, identifying user input information to obtain an identification result;
s1022, generating at least one display instruction according to the identification result and the working relation between at least two screens;
illustratively, the working relationship between the screens includes collaborative work, and generating at least one display instruction according to the recognition result and the working relationship between at least two screens includes:
According to the user input information, determining a target screen and a display instruction corresponding to each target screen from the screens of which the work relation is collaborative work, wherein the target screen in the embodiment comprises a screen which needs to be controlled in order to execute a display operation corresponding to the user input information, and each display instruction can instruct the corresponding target screen to perform display control so that each target screen can jointly complete the display operation.
It will be appreciated that in screen control, not all screens may be involved in each control. For example, the user may need to turn off or on only a part of the plurality of screens or change the display contents of a part of the screens, and thus, before controlling the screens, determine the target screen to be controlled. When it is determined that the display operation corresponding to the user input information is to close the screen, a display instruction for closing the screen is generated, each screen to be closed is determined, and the control terminal sends the display instruction for closing the screen to each screen to be closed.
In other examples, the operational relationship includes a synchronous operation, and determining at least one display instruction according to the user input information and the operational relationship between the respective screens includes:
And determining that the target screens comprise screens with synchronous working relation and determining a display instruction corresponding to each target screen according to the user input information, wherein the display instruction can instruct the corresponding target screen to perform display control so that each target screen respectively completes display operation corresponding to the user input information.
That is, the display instructions determined by the control terminal for the respective screens whose operation relationship is synchronous operation are identical, and the respective screens can perform the same display control.
In an example, before determining at least one display instruction, determining whether a screen to be controlled by a user is a screen with a working relationship of collaborative work or a screen with a synchronous work according to user input information, if the screen to be controlled by the user is the screen with the collaborative work, determining a target screen from the screens with the working relationship of collaborative work according to the user input information, and if the screen to be controlled by the user is the screen with the synchronous work, taking all the screens with the working relationship of synchronous work as the target screen. In another example, if the control terminal is only provided with one working relationship, the target screen can be directly determined without judging the working relationship of the screen to be controlled by the user, that is, the target screen is directly determined from the screen with the working relationship of the collaborative work when the control terminal only controls the screen with the collaborative work, or all the screens with the synchronous work are directly used as the target screen when the control terminal only controls the screen with the synchronous work.
In some embodiments, the working relationship between the screens may be set, where the setting manner includes, but is not limited to, directly inputting an instruction into the control terminal, or adopting the screen control method of this embodiment, inputting corresponding user input information on at least one screen, so that the control terminal performs setting according to the user input information acquired from the screen side.
In some practical applications, the working relationship between the screens may include, in addition to the above-mentioned working modes (including but not limited to independent working, cooperative working, and synchronous working), a positional relationship (including but not limited to a relative and absolute position) when each screen works, and in some implementations, according to the positions of the screens, it is determined which screens are controlled to determine the corresponding display instruction.
In some embodiments, each display instruction is sent to all the screens controlled by the control terminal, when the screen receives the corresponding display instruction, the display instruction is executed, if the display instruction received by the screen is not corresponding to the display instruction, the display instruction is not executed, and the control mode is also suitable for broadcast type message interaction, the control terminal broadcasts the display instruction to all the screens, and each screen executes the corresponding display instruction or does not execute the display instruction. Or the display instruction can be selected to be transmitted to the screen corresponding to the display instruction, for example, the determined display instruction corresponds to one screen only, and then the display instruction is transmitted to the corresponding screen only, so that transmission resources are saved through more accurate information interaction.
The user input information of the present embodiment includes, but is not limited to, gesture images, touch controls, voices, and the like of the user. Taking a gesture image with user input information as a user as an example, identifying the user input information, and obtaining an identification result comprises: and recognizing the gesture image to obtain a gesture motion track of the user, wherein the gesture motion track is used as a recognition result, and generating a display according to the gesture motion track. Similarly, when the user input information includes touch, the type of touch (including but not limited to sliding and clicking) and/or the position information of touch (including but not limited to sliding track and clicking position) are identified, and when the user input information includes voice, the voice is identified to obtain text or other voice information that the user wants to input.
In some embodiments, the control terminal and the screen controlled by the control terminal transmit information through wireless radio frequency, and correspondingly, obtain user input information sent by at least one screen in the controlled screen, including:
acquiring user input information sent by at least one screen in the controlled screens through wireless radio frequency;
sending a display instruction to a target screen, comprising:
and sending the display instruction to the target screen through the wireless radio frequency.
The wireless radio frequency includes, but is not limited to, wifi, bluetooth or other wireless radio frequency communication modes.
In some embodiments, obtaining user input information sent by at least one of the controlled screens includes:
acquiring user input information respectively sent by at least two screens in the controlled screens, and determining target user input information according to the at least two user input information;
determining at least one display instruction according to the user input information, including:
and determining at least one display instruction according to the determined target user input information.
For example, when a user touches or gestures on a large spliced screen, a touch track of the user may span multiple screens, or multiple screens near a hand of the user may sense gestures of the user, so that more than one screen acquires user input information, and the screens respectively send the acquired user input information to the control terminal, the situation that the control terminal receives the user input information sent by at least two screens in the controlled screens may occur. Of course, in other situations, such as multiple users operating multiple screens at the same time, it is also possible for the control terminal to receive more than one user input information.
And determining target user input information according to the user input information when the user input information sent by at least two screens is received. The target user input information may be one of the plurality of user input information with highest accuracy, or may be the target user input information which is obtained by integrating the plurality of user input information and re-calculating, or may be the target user input information which is determined by other modes and is finally used for determining the display instruction. In some implementations, the accuracy of the determination of the user's input can be improved by determining the target user input information from the user input information sent by at least two screens.
It should be understood that, in this embodiment, the screen for sending the user input information to the control terminal may be any screen controlled by the control terminal, where the screen may be a screen corresponding to the display instruction determined later (i.e., a screen controlled according to the user input information at this time), or may be a screen that does not receive the display instruction determined by the user input information (i.e., does not control the screen at this time). That is, by implementing the screen control method by the control terminal, the user can control not only the screen on which the user input information is acquired, but also other screens that are difficult for the user to reach through the screen.
According to the screen control method, the control terminal obtains user input information sent by at least one screen, the control terminal determines a display instruction of the screen according to the actual working condition of the screen, and the display instruction is sent to the corresponding screen, so that unified and convenient control over a spliced large screen or a distributed screen is realized. It can be appreciated that in practical application, the screen control method of the embodiment can not only realize the independent work of each screen, but also complete the cooperative work of the whole display system.
The present embodiment also provides a screen control method, which is applied to a screen, referring to fig. 3, and includes:
s201, establishing communication with a control terminal;
the communication connection includes wired or wireless communication, and exemplary wireless communication includes, but is not limited to, wireless radio frequency communication connections, such as wifi, bluetooth, or other wireless radio frequency communication means, and in some examples wireless broadcast or other communication means that do not require connection establishment may be used. For wired communications, the process of establishing communications includes, but is not limited to, connecting a communications cable, or accessing a communications port; for wireless communications that require connection establishment, the process of establishing a communication connection includes, but is not limited to, a pairing connection that performs wireless communications.
S202, receiving a display instruction sent by a control terminal;
the display instruction comprises a display instruction corresponding to a screen, wherein the display instruction is determined by the control terminal according to acquired user input information, and the user input information comprises user input information sent to the control terminal by at least one screen in the screens controlled by the control terminal.
S203, performing display control according to the display instruction;
by the screen control method applied to the screen, the screen can be displayed and controlled according to the user input information acquired by the screen controlled by the control terminal, and a user does not need to operate on the control terminal or the controlled screen, so that in some implementation processes, the screen can be effectively controlled in a multi-screen display scene such as a spliced large-scale screen or a distributed screen.
It will be appreciated that in some embodiments, the screen implementing the screen control method may also obtain user input information, where the user input information may be used to control other screens in the control terminal, and may also be used to control the screen from which the user input information is obtained.
The screen may obtain the user input information in any manner, for example, in some embodiments, before receiving the display instruction sent by the control terminal, the screen further includes: acquiring infrared reflection information through an infrared receiving and transmitting module and acquiring color information through a color sensing module;
And determining user input information according to the infrared reflection information and the color information, and sending the user input information to the control terminal so that the control terminal can determine a display instruction.
In some examples, the infrared reflection information and the color information can be directly used as user input information and sent to the control terminal, and in such examples, the control terminal can process the information to obtain corresponding data (including but not limited to obtaining data such as gesture motion tracks of a user after processing); in some examples, the infrared reflection information and the color information may be processed by a screen, and the processed data may be transmitted to the control terminal as user input information.
In an example, the infrared transceiver module may specifically include an infrared emitter and an infrared sensor, where the infrared emitter is configured to emit infrared rays outwards, the infrared sensor may receive infrared rays reflected by the outside, and the infrared reflection information obtained by the infrared transceiver module may determine whether an object exists in front of the screen, and may be used to detect gesture operations of a user, to obtain a gesture image of the user. The color information acquired by the color sensing module can be combined with the infrared reflection information to be analyzed and processed, so that a more accurate gesture image of the user is obtained, and the gesture operation performed by the user is judged by identifying gesture motion track and other data. Of course, in some examples, user input information such as gesture images can also be determined by the infrared transceiver module alone.
By the screen control method applied to the screen, the screen can receive the display instruction corresponding to the operation of the user on the screen and/or other screens controlled by the control terminal, which is sent by the control terminal, so that the screen can be systematically controlled. In some implementation processes, the problem that a spliced screen, a distributed screen and other multi-screen systems are difficult to control uniformly is solved, and a user can conveniently and rapidly perform touch, gesture, sound control and other operations on the screens in the multi-screen systems.
In order to better understand the screen control method provided by the present invention, a screen control method will be described below with reference to specific examples.
Referring to fig. 4, an example of a structure of a control terminal is shown, where the control terminal 100 includes a main control module 101 and a first radio frequency module 102, and the first radio frequency module 102 can implement data interaction with at least two screens.
Referring to fig. 5, a structure of a screen is illustrated, and the screen 200 includes a display panel including a plurality of light emitting chip sets 201, each light emitting chip set 201 including three light emitting chips of different colors, which may be, but not limited to, mini LED (sub millimeter light emitting diode) chips, micro LED chips (Micro light emitting diode) and the like. The screen 200 further includes a display driving unit 207 for providing data to the display panel according to the required control and display contents, and the display panel drives each light emitting chip set 201 to perform a specific display action according to the data provided by the display driving unit 207.
Taking Micro LED chips as an example, most of the display panel based on the Micro LED chip product is transparent, and the Micro LED chips are small in size, so that the transparent range of the display panel based on the Micro LED chip product is extremely high, in such an embodiment, the infrared emitter 202, the infrared receiver 203, and the color sensor 204 may be disposed below the display panel (on the side far away from the user when the user views the screen below the display panel referred to in this embodiment). In practical application, the information of the part blocked by the object such as the Micro LED chip can be supplemented by an algorithm or other part of the data of the reflected light.
A processing module 205 and a second rf module 206 are further disposed below the display panel, and the processing module 205 and the second rf module 206 may be disposed on a circuit board (not shown in the figure) below the display panel. In operation, the infrared emitter 202 continuously emits infrared rays to the upper side of the display panel (the upper side of the display panel in this embodiment is the side close to the user when the user views the screen), the infrared rays encounter objects such as the palm of the user and then are reflected to the infrared receiver 203, the infrared receiver 203 acquires infrared reflection information, and the color sensor 204 acquires color information of natural light. After receiving the data (including but not limited to the infrared reflection information and the color information) transmitted by the infrared receiver 203 and the color sensor 204, the processing module 205 analyzes and processes the received data to obtain a continuous motion track of the palm, i.e. identifies and obtains a gesture motion track of the user. For example, the gesture motion trajectory may be compared to a database, gesture meanings analyzed, and user input information (i.e., data representing the gesture meanings in this example) transmitted to the second rf module 206. The second rf module 206 may transmit user input information to the control terminal.
In an example, the control terminal may perform the screen control method applied to the control terminal provided in the above embodiment, and the screen may perform the screen control method applied to the screen provided in the above embodiment. An exemplary process of specifically controlling the screen by the user through gestures will be described below on the basis of the above screen and control terminal.
Example one: an independently operated screen a controlled by the control terminal is controlled by the screen control method of the above embodiment, see fig. 6.
