These and other aspects of the present application will be more readily apparent in the following description of embodiments.
In order to illustrate technical solutions in embodiments of the present disclosure more clearly, accompanying drawings that need to be used in describing embodiments of the present disclosure will be introduced below briefly. Obviously the accompanying drawings described below are only some embodiments of the present disclosure, and other accompanying drawings can also be obtained by those ordinary skilled in the art according to these accompanying drawings without creative labor.
In order to make objects, technical solutions and advantages of the present disclosure more clear, the present disclosure will be described in further detail below with reference to accompanying drawing. Obviously, the described embodiments are only a portion of embodiments of the present disclosure, but are not all embodiments. Based on embodiments in the present disclosure, all other embodiment obtained by the skilled in the art without creative effort fall within the scope of the present disclosure.
In embodiments of the present disclosure, the term “and/or” describes an association relationship between associated objects, indicating that there may be three relationships, for example, A and/or B can represent three cases: A exists alone, A and B exist simultaneously, and B exists alone. The character “/” generally indicates that an association relationship between the associated objects before and after the character is an “or” relationship.
Application scenarios described in embodiments of the present disclosure are intended to more clearly illustrate technical solutions of embodiments of the present disclosure, but do not constitute a limitation to technical solutions according to embodiments of the present disclosure. The skilled in the art will know that, with the emergence of new application scenarios, the technical solutions according to embodiments of the present disclosure are also applicable to similar technical problems. In the description of the present disclosure, “a plurality” means two or more unless otherwise specified.
In the scenario of smart conference, it is generally necessary to use a large-size (generally more than 50 inches) display device and use the touch function of the display device with a stylus to perform touch operations, for example, to perform writing operations through the stylus and perform writing setting through a menu bar corresponding to the stylus. However, at present, in the process of touch operation, a display position of the menu bar corresponding to the stylus on the display device is fixed. For example, the menu bar is displayed at a lower right corner of a display screen of the display device. Due to the large size of display device in the current conference scenario, a user needs to move to the fixed display position of the menu bar every time the user needs to operate a menu in the menu bar. Therefore, in the conference scenario based on the large-size display device, the user needs to move back and forth to operate the menu in the menu bar, reducing the convenience of using the menu bar, and the user's conference experience is poor.
The display device in the embodiments of the present disclosure is a large-size (generally more than 50 inches) display device, is configured with a touch function, and is a device that can be used with a stylus for touch operations, such as writing operations, chart drawing operations, etc. Writing programs such as an electronic whiteboard may also be installed on the display device. A user may write on the display device using a finger, an active pen, a passive pen, etc. The display device may include a Liquid Crystal Display (LCD), an organic light-emitting semiconductor (Organic Electroluminescence Display, OLED), an electronic ink and other display modules, and can display handwriting in real time.
In order to solve the technical problem of decreased convenience of using the menu bar due to the fixed display position of the menu in the current smart conference scenario, embodiments of the present disclosure provide a display method of a menu bar. The display position of the menu bar can be changed according to the movement of a touch instruction. In the scenario of using a large-size display device for a smart conference, it is convenient for the user to operate the menu bar nearby during the writing process without moving back and forth to the fixed position, saving conference time and improving conference efficiency.
The core idea of the display method of the menu bar according to embodiments of the present disclosure is that, the display position of the menu bar is determined according to the touch position of the touch instruction detected by the display device, and considering operation requirements of a user, under the condition that the normal writing of the user is not affected as much as possible, the displayed menu bar is set to be able to change with the movement of the touch position. Therefore, when the user moves a large distance from the initial writing position in the writing process, there is no need to return to the initial writing position or a fixed position to operate the menu bar; instead, the menu bar will be displayed near the current touch position. Therefore, the situation that the user repeatedly moves back and forth to operate the menu bar can be effectively reduced, and the conference efficiency is improved.
As shown in
The display screen is configured to display content.
The control circuit includes a processor and a memory. The memory is configured to store a program executable by the processor. The processor is configured to read the program in the memory and perform following steps:
In implementations, after the display device detects touch instruction(s) generated by one or more users, the touch position(s) of the touch instruction(s) generated by the user(s) is/are first determined. The touch instruction includes, but is not limited to, a writing instruction. Display content includes, but is not limited to, a writing trajectory. The touch position of the touch instruction can be understood as the position where the touch instruction is generated. It should be noted that the touch instruction generated by each user can be an instruction generated by a writing trajectory, which is a series of trajectory points, and can also be an instruction generated when clicking, double-clicking or drawing a chart. That is, the user can click on an icon, write, draw a chart and so on to generate a corresponding touch instruction. The touch instruction in the present embodiments includes, but is not limited to, at least one of a touch instruction generated by writing by the user, a touch instruction generated by clicking or double-clicking by the user, or a touch instruction generated when the user draws a chart. The touch instruction generated by each user operation can be used to determine a corresponding first menu bar.
In implementations, when the user performs the touch operation of writing on the display screen of the display device, a touch instruction is generated at the writing position, and the writing position refers to the touch position of the touch instruction. With the movement of the user's writing position, the corresponding touch position also moves therewith. The display position of the first menu bar corresponding to the current touch instruction is determined according to the current touch position. In the writing process, the first menu bar on the display screen also changes with the writing trajectory. When touch instructions generated by a plurality of users are detected, it indicates that there may be a plurality of persons writing in the conference scenario. For each user, the touch instruction generated in the writing process of the each user corresponds to a first menu bar. When a plurality of users write simultaneously, the first menu bar corresponding to each user is displayed at a position corresponding to the writing position of the user. The display position of the first menu bar of each user is determined according to a touch position of a touch instruction generated by the each user in the writing process. Therefore, no matter one or a plurality of users use the display device to perform touch operation, for the trajectory written by the user, a first menu bar is displayed in the vicinity of the current writing position of the user, which is convenient for the user to perform corresponding operations on icons in the first menu bar.
In some embodiments, the present embodiments generate the display content according to the touch instruction. The display content includes, but is not limited to, text, charts, etc. The first menu bar in the present embodiments is used to edit the display content.
In some embodiments, icons in the first menu bar in the present embodiments may be used to edit the written content, include, but are not limited to, at least one of the color of the display content, the thickness of lines, font type, font size, line spacing, bolding, underlining, adding a corner mark, zooming in/out, adding a mark, modifying, copying, and pasting. In implementations, when the user uses the stylus to write on the display device, the display content corresponding to the user's writing can be edited through the first menu bar to change the color of the display content.
The editing of the display content includes, but is not limited to, the editing of writing parameters before writing (for example, setting of parameters of a stylus), editing the displayed content during and after writing, such as modifying the color, line type, line thickness, bolding, zooming in, zooming out, etc., of the displayed content.
As shown in
As shown in
In some embodiments, the present embodiments may further generate a plurality of first menu bars, and the plurality of the first menu bars are located at different positions of the display screen.
In some embodiments, when touch instructions generated by a plurality of users are received, a plurality of first menu bars are generated. The touch instructions generated by the users are in one-to-one correspondence with the first menu bars. Display positions of the first menu bars corresponding to the touch instructions generated by different users are different. Therefore, when different users write simultaneously, the first menu bars are correspondingly displayed according to different writing positions of respective users, which is convenient for each user to operate the first menu bar, and the conference efficiency is improved.
When there is a case where a plurality of users operate the display screen simultaneously, the present embodiments further provide a method for distinguishing touch instructions of a plurality of users, which includes following steps.
When the display device detects a plurality of touch instructions, in this case, it cannot be determined whether the detected plurality of touch instructions are generated by the same user or by different users. A difference in detection time between detected adjacent touch instructions in terms of detection time, and a distance between touch positions of the adjacent touch instructions may be determined first. When the difference is less than a time threshold and the distance is greater than a distance threshold, it is determined that touch instructions of a plurality of users are detected.
In some embodiments, when two or more touch instructions are detected simultaneously, a distance between touch positions of any two touch instructions is determined, and when the distance is greater than a distance threshold, it is determined that a plurality of touch instructions of a plurality of users are detected. When three touch instructions (A, B, C) are detected simultaneously, among the three touch instructions, distances between touch positions of different touch instructions are determined, that is, a distance AB between A and B is determined, a distance AC between A and C is determined, a distance BC between B and C is determined. When AB is greater than the distance threshold, it indicates that A and B may be touch instructions of two users. When AB is not greater than the distance threshold, it indicates that A and B are touch instructions of one user.
It is easy to understand that when a plurality of touch instructions are generated by the same user, then according to the writing rule of the user, a distance between touch positions of adjacent touch instructions is small, and a determination condition that a plurality of users generate the touch instructions is not satisfied. When the touch instructions are generated by a plurality of users, then a distance between touch positions of touch instructions generated by different users must be greater than the distance threshold, and because it is often a case that different user are writing simultaneously, the difference between the detection time of the detected adjacent touch instructions must be less than the time threshold, and it may be determined that the touch instructions received in this case are different touch instructions generated by different users.
In some embodiments, touch instructions generated by a plurality of users in the present embodiments may be touch instructions generated by simultaneous writing operations of a plurality of users, or, touch instructions generated by alternate writing operations of a plurality of users. In the present embodiments, the touch instruction generated by a single user and the touch instructions generated by a plurality of users can be distinguished through the above determination method.
In some embodiments, the touch instruction generated by the user in the present embodiments includes, but is not limited to, any one or more of the following.
One is that the touch instruction includes an instruction generated by a user using a stylus to touch a display screen of the display device.
The other one is that the touch instruction includes an instruction generated by a finger of a user touching a display screen of the display device.
It should be noted that for a touch instruction generated by each user, the principle of the display method of the corresponding first menu bar is the same, and the display of first menu bars corresponding to the touch instructions generated by different users can be implemented based on the same principle. Taking the display of a first menu bar corresponding to a touch instruction generated by a user as an example, the display method of the first menu bar in the present embodiments will be described in detail.
In the display method of the first menu bar in the present embodiments, first menu bars can be displayed in different regions divided for the display screen based on a plurality of regions divided in advance for the display screen of the display device. With the movement of the touch position, a region of the displayed first menu bar is determined according to the region where the touch position is located. Alternatively, there may be no region division, and real-time following method is adopted. That is, the display position of the first menu bar is determined according to the current touch position. An implementation includes, but is not limited to, following two embodiments.
In a first embodiment, a display position is determined according to a region where a touch position is located.
In implementations, the display screen of the display device may be divided into a plurality of regions in advance. The division here is not a real physical division, but a concept of division derived to illustrate how to determine the display position. In the actual implementations, the user will not perceive whether the display screen is divided and how may parts the display screen is divided into. After a plurality of regions divided for a display device are determined in advance, a region where the touch position of the touch instruction is located is determined from a plurality of regions divided for a display screen of that display device, and a display position of the first menu bar corresponding to the touch instruction is determined in the region where the touch position is located.
In a case where the display screen of the display device in the present embodiments is divided into two regions of left and right, as shown in
In a case where the display screen of the display device in the present embodiments is divided into four regions, as shown in
Optionally, after the region where the touch position is located is determined, the region where the display position of the first menu bar is located is determined. That is, the first menu bar and the touch position are located in the same region. In the same region, the position where the first menu bar is located includes, but is not limited to, a lower side, a left side, a right side, an upper side, or a position different from the touch position in the region, which may be set according to actual requirements, and the present embodiment does not limit it too much.
In a second embodiment, a display position is determined according to a touch position.
A touch position of a touch instruction on a display screen of the display device is determined. A display position of a first menu bar of a stylus is determined within a preset region centering on the touch position.
In the embodiments, the first menu bar continuously moves according to the movement of the touch position of the touch instruction. The first menu bar is located in a preset region with the touch position as the center. The preset region includes at least one of a circular region, a square region or a polygonal region. For example, the first menu bar is located on a circumference, a box, or the like with the touch position as the center, so that the user can conveniently operate the chart in the first menu bar in the writing process, improving the use experience of the user, and improving the conference efficiency.
As shown in
It should be noted that when there are a plurality of users writing simultaneously, and preset ranges corresponding to touch positions of touch instructions generated by a plurality of users are overlapped, first menu bars respectively corresponding to the touch instructions generated by respective users are not overlapped.
In some embodiments, before the user generates the touch instruction, the present embodiments further provide a method for activating display of the first menu bar, and the core idea is to activate the display of the first menu bar using an activation instruction generated by the user. That is, to determine an initial display position of the first menu bar to display. In implementations, the initial display position of the first menu bar in the present embodiments is determined according to an activation position corresponding to the activation instruction, and the activation instruction is issued by the user. The activation position is essentially related to the user's position when the user issues the activation instruction. Therefore, the initial display position of the first menu bar in the present embodiments is related to the user's position, so that the initial display position is close to the user's position, and it is convenient for the user to preform relevant operations on icons in the first menu bar.
In implementations, before determining the display position of the first menu bar corresponding to the touch instruction according to the touch position of the touch instruction, in the present embodiments, the initial display position of the first menu bar may be determined according to the activation instruction generated by the user as follows.
In response to an activation instruction generated by at least one user, an initial display position of a first menu bar corresponding to the activation instruction is determined according to an activation position corresponding to the activation instruction. The first menu bar corresponding to the activation instruction is displayed at the initial display position.
When only one user performs touch operation at present, then in response to an activation instruction generated by the user, the initial display position is determined according to the activation position, so that the use experience of the user is improved, and the user can conveniently set the displayed first menu bar according to the writing preference of the user before writing, improving the use experience of the user.
In some embodiments, the activation instruction includes any one or more of the following types.
First type: the activation instruction includes an instruction generated when the user removes a stylus from the display device.
It should be noted that in this way, when two or more styluses are removed from the display device simultaneously, then the generated activation instructions represent activation instructions generated by a plurality of users.
Second type: the activation instruction includes an instruction generated when a finger of the user contacts the display screen of the display device and received for a first time after startup.
In this way, when instructions generated by fingers of a plurality of users touching the display screen of the display device are received, then the generated activation instructions are activation instructions generated by a plurality of users.
In some embodiments, the present embodiments determine the initial display position of the first menu bar corresponding to the activation instruction through any one of following methods.
Method 1: the activation instruction is related to the stylus.
In implementations, the activation instruction is an instruction generated when the user removes the stylus from the display device, then the activation position corresponding to the activation instruction is the position where the stylus is placed outside the display device.
When the activation position is the position where the stylus is placed outside the display device, an initial display position of the first menu bar is determined in a region at a side of a display screen of the display device immediately adjacent to the activation position, which includes, but is not limited to, any one or more of following cases.
Case 1) when the activation position is a position where the stylus is placed at a left outer side of the display device, an initial display position of the first menu bar is determined in a left region of the display screen immediately adjacent to the activation position. As shown in
Case 2) when the activation position is a position where the stylus is placed at a right outer side of the display device, an initial display position of the first menu bar is determined in a right region of the display screen immediately adjacent to the activation position. As shown in
Case 3) when the activation position is a position where the stylus is placed at a lower outer side of the display device, an initial display position of the first menu bar is determined in a lower region of the display screen immediately adjacent to the activation position. As shown in
Case 4) when the activation position is a position where the stylus is placed at an upper outer side of the display device, an initial display position of the first menu bar is determined in an upper region of the display screen immediately adjacent to the activation position. As shown in
In some embodiments, an outer side of the display device includes at least two positions for placing styluses. The processor is configured to perform:
In implementations, when two styluses are placed outside the display device, then the display device is divided into two regions (a first region and a second region). One region represents an adjacent region adjacent to a position of the stylus (activation position), and the other region represents a distant region distant from the position of the stylus (activation position). When the two styluses are placed at the same position, then the initial display position of the first menu bar is located in the vicinity of the position of the styluses. When the two styluses are not placed at the same position, a first stylus is placed at a side adjacent to the first region, and a second stylus is placed at a side adjacent to the second region, then the initial display position of the first menu bar of the first stylus is located in the first region, and the initial display position of the first menu bar of the second stylus is located in the second region. When three styluses are placed outside the display device, a first stylus, a second stylus and a third stylus are respectively placed at a first position, a second position and a third position, then the display device may be divided into three regions, where a first region is adjacent to the first position, a second region is adjacent to the second position, and a third region is adjacent to the third position, the initial display position of the first menu bar of the first stylus is located in the first region, the initial display position of the first menu bar of the second stylus is located in the second region, and the initial display position of the first menu bar of the third stylus is located in the third region. When more than three styluses are placed outside the display device, then the initial display position of the first menu bar corresponding to each stylus can also be determined according to the above method, which is not limited in the embodiments.
Method 2: the activation instruction is related to the user.
In implementations, the activation instruction is an instruction generated when a finger of the user contacts the display screen of the display device and received for a first time after startup, the activation position corresponding to the activation instruction is a position on the display screen of the display device.
When the activation position is a position on the display screen of the display device, an initial display position of the first menu bar is determined in a region of the display screen including the activation position, where the display screen includes a plurality of divided regions.
As shown in
As shown in
As shown in
In some embodiments, as shown in
In some embodiments, the present embodiments may also display a second menu bar. The second menu bar may be displayed after startup, or may be displayed after receiving a touch instruction for the first time, or may be displayed after receiving the activation instruction of the user, which is not limited in the present embodiments. The content displayed by the second menu bar in the present embodiments is different from that of the first menu bar. The first menu bar is used for editing the display content, and the second menu bar is used for providing additional functions, such as modifying the overall background of the display screen, switching the color of the background, switching the display mode, and providing the function of scanning and saving. For example, when the function of scanning and saving in the second menu bar is clicked, a two-dimensional code is displayed on the display screen, so that a user terminal can upload currently displayed content to the user terminal by scanning the two-dimensional code.
In implementations, after the initial display of the second menu bar, the position of the second menu bar on the display screen is fixed.
In some embodiments, after displaying the first menu bar and the second menu bar simultaneously, the first menu bar and the second menu bar are controlled to be fused into one menu bar within at least one set range centering on a touch position of a touch instruction generated by a user. In practice, when the user's writing moves to the vicinity of the second menu bar (the second menu bar is within a set range centering on the touch position of the touch instruction generated by the user), in this case, the first menu bar and the second menu bar are controlled to be combined into one menu bar. It should be noted that, the combination in the present embodiments refers to combining icons in the first menu bar and icons in the second menu bar to generate a new menu bar. The icons in the first menu bar and the icons in the second menu bar may be simultaneously displayed in the new menu bar.
In some embodiments, the icons in the first menu bar in the present embodiments may be used to edit the written content, including but not limited to modifying, copying, pasting, font setting, font color setting, line thickness setting, displayed font size, line spacing, etc. The second menu bar may make various settings for the display device and/or the display screen, including but not limited to background, picture brightness, etc., and can also provide the function of scanning and saving. The functions involved in the first menu bar are not limited too much in the present embodiments. The number, function, size and the like of the icons included in the first menu bar are not limited too much, and can be determined according to actual requirements.
In some embodiments, the present embodiments may also set the first menu bar to disappear after it is determined that there is no operation by the user, so that the first menu bar can be automatically opened (that is, the first menu bar is displayed) and automatically closed (that is, the first menu bar is controlled to disappear), providing a method in which a user does not need to manually open and close the first menu bar, and improving the use experience of the user.
In implementations, whether the first menu bar is closed or not is determined by any one or more of following determination methods.
(1) When the touch instruction is not detected again within a preset time period after the touch instruction is detected, the first menu bar corresponding to the touch instruction is controlled to disappear from the display screen.
In implementations, when the user does not operate the display screen for a long time after writing, the first menu bar corresponding to the touch instruction generated by the user is controlled to disappear from the display screen.
(2) When a difference in detection time between adjacent touch instructions is larger than a preset value, the first menu bar corresponding to the touch instruction with earlier detection time is controlled to disappear from the display screen.
In implementations, when the time difference between touch instructions generated by the user writing twice is large, the first menu bar corresponding to the touch instruction with earlier time is controlled to disappear from the display screen, and only the first menu bar corresponding to the touch instruction of the latest time is displayed.
(3) When a return instruction generated when a stylus is placed back on the display device is detected, the first menu bar corresponding to the touch instruction generated by the stylus is controlled to disappear from the display screen.
In implementations, when the user puts the stylus back on the display device after finishing writing with the stylus, the first menu bar corresponding to the touch instruction generated by the stylus is controlled to disappear from the display screen.
In some embodiments, the present embodiments provide an implementation flow of displaying the first menu bar in a case that the user is not writing. In implementations, the user can use the stylus to write, draw and the like at will on an electronic whiteboard interface of the display device, and operates the displayed first menu bar. The stylus can be attached to one side of the left side, the right side, the upper side and the lower side of the display device, and the display device allows two or more styluses to be used simultaneously.
When the stylus is attached to the right side of the display device, when the user removes the stylus from the right side, at this time, the display device detects an instruction (i.e., an activation instruction) generated when the stylus is removed from the right side, a first menu bar corresponding to the stylus on the right side of the display device is displayed, where a display position of the first menu bar may be at the lower right side. Optionally, it may be set in advance that when an activation instruction is detected, the first menu bar is fixed at a preset position of the display screen for display.
When the stylus is attached to the left side of the display device, when the user removes the stylus from the left side, at this time, the display device detects an instruction (i.e., an activation instruction) generated when the stylus is removed from the left side, a first menu bar corresponding to the stylus on the left side of the display device is displayed, where a display position of the first menu bar may be at the lower left side. Optionally, it may be set in advance that when an activation instruction is detected, the first menu bar is fixed at a preset position of the display screen for display.
In some embodiments, the present embodiments further provide an implementation flow of displaying the first menu bar in a case that the user is writing. In implementations, the user can use the stylus to write, draw and the like at will on an electronic whiteboard interface of the display device, and operates the displayed first menu bar. The display device allows two or more styluses to be used simultaneously. In a case that the user is writing, the present embodiments mainly provide two methods of displaying the first menu bar. One is that in a plurality of regions divided for the display screen, with the movement of the region of the user's writing trajectory in the display screen, the first menu bar also moves in the corresponding region, and the other is that the first menu bar moves with the movement of the user's writing trajectory. No matter which display method is adopted, the first menu bar can move along with the movement of the user, which is more convenient for the user to operate the first menu bar.
In some embodiments, the present embodiments further provide a multi-user writing situation, where the user can independently select to enter a multi-person writing mode in an electronic whiteboard interface, and can also activate the multi-person writing mode by removing the stylus before the user enters the writing mode. The activation is as follows.
(1) When two styluses are attached to a display device, when users take off the two styluses simultaneously, the display device determines that activation instructions generated by two users are received, and the multi-person writing mode is automatically activated, entering the case of multi-person writing, at this time, first menu bars corresponding to the two styluses may be displayed on the display screen simultaneously.
(2) When two styluses are attached to a display device, when a time difference between removals of the two styluses by users is less than a threshold value, the display device determines that activation instructions generated by two users are received, and the multi-person writing mode is automatically activated, entering the case of multi-person writing, at this time, first menu bars corresponding to the two styluses may be displayed on the display screen simultaneously.
To sum up, the display method for the first menu bar according to the present embodiments can realize the effect of following the movement of the user in the writing process of the user, so that the user can easily perform related operations on the displayed first menu bar no matter which position the user moves to, improving the use experience of the user, reducing the repeated action of moving back and forth, and improving the conference efficiency.
Based on the same inventive concept, embodiments of the present disclosure further provide a display method for a menu bar, because this method is the method used by the display device in embodiments of the present disclosure, and the principle of solving the problem by the method is similar to that of the display device, implementations of the method can be referred to implementations of the display device, and the repetition is not repeated.
