Detailed Description

In order to make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

It should be understood that the embodiments described are only a few embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the application, as detailed in the appended claims.

In the description of the present application, it is to be understood that the terms "first," "second," "third," and the like are used solely to distinguish one from another and are not necessarily used to describe a particular order or sequence, nor are they to be construed as indicating or implying relative importance. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate. Further, in the description of the present application, "a plurality" means two or more unless otherwise specified. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

Fig. 1 is a schematic view of an application scenario provided by the present application, and as shown in fig. 1, a terminal device a and an intelligent interactive panel B may share a picture through a screen projection technology, where the terminal device a is a sending end, and the intelligent interactive panel B is a receiving end. The display content of the terminal device A can be displayed in the intelligent interactive panel B in real time. In a group communication situation, such as a conference lecture, a lecturer may perform a demonstration operation on the content displayed by the intelligent interactive tablet B near the intelligent interactive tablet B. The intelligent interactive panel B is integrated with the electronic whiteboard, the canvas interface of the electronic whiteboard can be displayed through the display screen of the intelligent interactive panel B, and when a presenter marks the content of a presentation and the like, the presenter can operate the canvas interface of the electronic whiteboard in the display screen to input corresponding marks. After the speaker inputs a plurality of marks, the display levels of the marks are different, and if two marks overlap each other, a mark having a high display level is displayed on a mark having a low display level.

One current implementation is: when one of the marks needs to be modified, for example, the position of one mark needs to be moved, and in the process of dragging the mark to move, if the mark passes through other marks with higher display levels originally, the mark is displayed on the other marks due to the fact that the mark subjected to post-operation has a higher display level, and the original display level sequence is damaged, so that in order to keep the original display level sequence unchanged, in the process of moving the mark, other marks influenced by the mark are determined in real time, and then the other marks are redrawn in real time, so that the original display level sequence is ensured to be unchanged. However, in this way, during the movement of the mark, other marks affected by the mark need to be calculated in real time and redrawn in real time, which occupies too much processing resources and causes performance degradation.

Therefore, the display hierarchy of the mark to be modified is set to be higher than the display hierarchies of other marks, the mark is modified, and after the mark is modified, the display hierarchy of the mark is changed to the original display hierarchy, so that the display hierarchy of each mark is not changed after the mark is modified, the writing effect is not influenced, other marks influenced by the process of modifying the mark are not required to be determined in the process of modifying the mark, and the other marks are not required to be redrawn, processing resources are saved, and the performance is improved. In the process of modifying the marks, the user does not care about the display hierarchical order of each mark, and the user experience is not reduced. Specific implementation schemes of the present application can be referred to in the following description of the embodiments.

In the following, the smart interactive tablet is explained.

According to the working principle of the touch assembly and the medium for transmitting information, the touch assembly can be divided into four categories: resistive, capacitive, electromagnetic, infrared, and surface acoustic wave.

When a user touches the display screen by a finger or a pen, the touch assembly can acquire data of touch points and send the data to the intelligent processing system, and then different functional applications are realized along with software built in the intelligent processing system, so that touch control of the intelligent processing system is realized.

The 'screen' and 'large screen' mentioned in the application refer to the display screen of the intelligent interactive flat panel; the intelligent interaction panel displays a certain interface, namely the display screen of the intelligent interaction panel displays the interface.

It should be noted that, for the sake of brevity, this description does not exhaust all alternative embodiments, and it should be understood by those skilled in the art after reading this description that any combination of features may constitute an alternative embodiment as long as the features are not mutually inconsistent.

Fig. 2 is a flowchart of an operation method of an intelligent interactive tablet according to an embodiment of the present application, and as shown in fig. 2, the method of this embodiment may include:

s201, displaying a canvas interface of the electronic whiteboard.

In this embodiment, the intelligent interactive tablet includes an electronic whiteboard, and the intelligent interactive tablet may display a canvas interface of the electronic whiteboard through the display screen. The electronic whiteboard is used for displaying elements input by a user based on contents projected by the terminal device onto the intelligent interaction panel, wherein the elements can be marks such as characters, letters, numbers, symbols, graphics and the like. Each element is mainly displayed on a canvas interface of the electronic whiteboard, and the intelligent interactive panel can display the canvas interface of the electronic whiteboard through the display screen.

S202, when the canvas interface comprises a plurality of elements, the display hierarchies of the elements are different, element selection operation on the canvas interface is received, a target element is determined from the elements according to the element selection operation, and the target element is the first display hierarchy in the display hierarchy sequence of the elements.

In this embodiment, when a plurality of elements are included in the canvas interface of the electronic whiteboard, and the display hierarchies of the plurality of elements are different from each other, there is a high-low order between the display hierarchies of the elements, and when at least two elements overlap at the same position, the element with the low display hierarchy at the overlapping position is covered by the element with the high display hierarchy.

When a user needs to modify any one of the plurality of elements, the user performs an element selection operation on the canvas interface, for example, the user touches any one of the plurality of elements in the canvas interface through the display screen, and accordingly, the intelligent interaction tablet can receive the element selection operation on the canvas interface, generate an element selection instruction according to the element selection operation, and determine a target element from the plurality of elements according to the element selection instruction. Wherein the target element is a first display level, such as a lowest display level, a next to last lower display level, and the like, in the display level order of the plurality of elements.

Taking 3 elements as an example, as shown in fig. 3, the 3 elements are respectively circular, triangular and rectangular, wherein, as shown in (a) in fig. 3, the 3 elements are displayed in the canvas interface of the electronic whiteboard, and the display hierarchy of the circular is lower than that of the triangular, which is lower than that of the rectangular. The circle and the triangle are overlapped, and the triangle covers a part of the area of the circle because the display level of the triangle is higher than that of the circle. Moreover, the triangle and the rectangle have an overlapping position, and the display level of the rectangle is higher than that of the triangle, so that the rectangle covers a part of the area of the triangle.

When the user wants to modify the triangle, the user may perform a selection operation on the displayed triangle, such as touching any location in the triangle area. Accordingly, the smart interactive tablet determines that the user selected a triangle among the 3 elements according to the user's operation, and the triangle is in the order of the last-but-one lower display level at the display level of the 3 elements.

S203, the target element is displayed from the first display level to the second display level in the canvas interface.

In this embodiment, if it is determined that the target element is selected by the user, the target element is displayed in the canvas interface at the second display hierarchy from the first display hierarchy, where the second display hierarchy is higher than the display hierarchies of other elements in the plurality of elements, so that the target element may be covered on any other element and the target element is not covered by other elements.

For example, as shown in (b) of fig. 3, when the target element selected by the user is a triangle, the triangle is displayed as the second display level from the penultimate low display level, that is, the triangle is changed and displayed before the rectangle is overlaid on the triangle, and the display level of the triangle is higher than that of the rectangle.

And S204, receiving element modification operation on the canvas interface, and correspondingly modifying the target element of the second display level according to the element modification operation.

In this embodiment, after the target element is displayed as the second display hierarchy in the canvas interface, it indicates that the user has successfully selected the target element, and then the user inputs an element modification operation on the canvas interface, and accordingly, the intelligent interaction tablet may receive the element modification operation on the canvas interface, generate an element modification instruction according to the element modification operation, keep the display hierarchy of the target element unchanged as the second display hierarchy, and perform corresponding modification on the target element of the second display hierarchy according to the element modification instruction.

Wherein the element modification operation may include one or more of: an element move operation, an element zoom operation, an element rotate operation, an element color change operation, and the like.

As shown in (c) of fig. 3, the position of the triangle is modified in accordance with the element moving operation with the element modifying operation as the element moving operation. For example, the user drags the triangle to change the position of the triangle, and then the position of the triangle is changed according to the dragging track of the user. Wherein the displayed triangle remains at the second display level, i.e. the triangle remains overlaid on the rectangle, during the dragging of the triangle to the target position by the user.

And S205, receiving a modification confirmation operation on the canvas interface, and displaying the display hierarchy of the modified target element from the second display hierarchy to the first display hierarchy in the canvas interface according to the modification confirmation operation.

In this embodiment, when the user does not modify the target element any more, the user inputs a modification confirmation operation on the canvas interface, and accordingly, the intelligent interaction tablet may receive the modification confirmation operation on the canvas interface, generate a modification confirmation instruction according to the modification confirmation operation, and display the modified display hierarchy of the target element from the second display hierarchy to the first display hierarchy in the canvas interface according to the modification confirmation instruction, so that the modification of the target element is completed, and the display hierarchies of the plurality of elements after the target element is modified remain unchanged.

As shown in (d) in fig. 3, when the user does not modify the triangle any more, the user may lift the hand touching the triangle, and the touch operation of the user on the screen interface changes, and accordingly, the intelligent interactive interface detects that the touch operation of the user disappears, which is equivalent to receiving a modification confirmation operation of the user on the screen interface. And generating a modification confirmation instruction according to the modification confirmation operation, and displaying the display hierarchy of the triangle from the second display hierarchy to the previous penultimate low display hierarchy in the canvas interface according to the modification confirmation instruction. That is, the triangle is modified from being overlaid on the rectangle to be displayed as a rectangle overlaid on the triangle.

According to the control method of the intelligent interactive tablet, when the canvas interface comprises a plurality of elements, the target elements are determined from the elements according to the element selection operation; displaying the target element from the first display level to a second display level in the canvas interface; then according to the element modification operation, correspondingly modifying the target element of the second display level; and according to the modification confirmation operation, displaying the modified display hierarchy of the target element from the second display hierarchy to the original display hierarchy in the canvas interface. Therefore, after the elements are modified, the display levels of the elements cannot be changed, and the original drawing effect is not influenced. In addition, in the process of modifying the target element, the target element is kept at the second display level, other elements influenced by the process of modifying the target element do not need to be determined, the original display level does not need to be kept unchanged in the process of modifying the target element, and after the target element is modified, the display level of each element is changed into the original display level, so that processing resources can be saved, and the performance can be improved. The user mainly concerns about the modified result, and in the process of modifying the target element, the user does not concern about the display hierarchical sequence of each element so that the user experience is not reduced.

On the basis of the above embodiment, the second display hierarchy is the highest display hierarchy, so that it can be ensured that the display hierarchy of the modified target element is higher than that of any element.

Fig. 4 is a flowchart of a control method of an intelligent interactive tablet according to another embodiment of the present application, and as shown in fig. 4, the method of this embodiment may include:

s401, displaying a canvas interface of the electronic whiteboard.

In this embodiment, the content displayed on the canvas interface of the electronic whiteboard includes an overlay result of a first layer and a second layer, where a display level of the first layer is lower than that of the second layer, the first layer may be referred to as a bottom layer (bitmap _ under), and the second layer may be referred to as a top layer (bitmap _ above). The canvas interface displays the result that the elements in the second layer are superposed on the elements in the first layer, and if the elements in the second layer and the elements in the first layer have an overlapped position, the elements in the second layer are overlaid on the corresponding elements in the first layer at the position. And the display levels of all the elements in the first layer are different.

The display hierarchy of the second layer is a second display hierarchy, and in this embodiment, the second display hierarchy is taken as a highest display hierarchy, which may ensure that the display hierarchy of the second layer is higher than that of any other layer.

And if the second layer does not comprise any element, the content displayed on the screen interface of the electronic whiteboard is the elements in the first layer.

Before a user operates the elements, the elements are drawn in the first layer, and at the moment, the elements in the second layer are empty.

Taking the multiple elements as a circle, a triangle, and a rectangle as an example, as shown in fig. 5, at this time, the user does not operate the elements, the circle, the triangle, and the rectangle are located in the first layer, the second layer is empty, and at this time, the content displayed on the screen interface is the same as the content in the first layer. And the display level of the circle is lower than that of the triangle, which is lower than that of the rectangle.

S402, when the first layer comprises a plurality of elements displayed on the picture interface, receiving element selection operation on the canvas interface, and determining a target element from the plurality of elements in the first layer according to the element selection operation, wherein the target element is a first display level in the display level sequence of the plurality of elements.

In this embodiment, a plurality of elements displayed in a canvas interface of an electronic whiteboard are drawn in a first layer, display hierarchies of the plurality of elements in the first layer are different from each other, a high-low order exists between the display hierarchies of the elements, and when at least two elements overlap at the same position, the element with the lower display hierarchy at the overlapping position is covered by the element with the higher display hierarchy.

When a user needs to modify any one of the plurality of elements, the user performs an element selection operation on the canvas interface, for example, the user touches any one of the plurality of elements in the canvas interface through the display screen, accordingly, the intelligent interaction tablet may receive the element selection operation on the canvas interface, generate an element selection instruction according to the element selection operation, and determine a target element from the plurality of elements in the first layer according to the element selection instruction. Wherein the target element is a first display level, such as a lowest display level, a next to last lower display level, and the like, in the display level order of the plurality of elements.

Before an element selection operation received on a canvas interface is performed, the first layer comprises the plurality of elements for introduction:

when the element displayed on the canvas interface is empty, the element in the first layer and the element in the second layer are also empty, when a user wants to draw the element in the picture interface, the user executes element drawing operation on the canvas interface, correspondingly, the intelligent interactive flat plate can receive the element drawing operation on the canvas interface, the corresponding element is drawn in the first layer according to the element selection operation, the user executes the element drawing operation for multiple times, and accordingly, multiple elements can be drawn in the first layer.

The drawing order of each element is different, and the display hierarchy of the element drawn first is lower than that of the element drawn later, so in this embodiment, the display hierarchy order of the elements can be determined according to the drawing order of the elements.

S403, migrating the target element from the first layer to the second layer, and displaying the display level of the target element as the highest display level in the canvas interface.

In this embodiment, after it is determined that a user selects a target element, the target element in the first layer is migrated to the second layer, and since the display level of the second layer is higher than that in the first layer, the display level of the target element migrated to the second layer is higher than that of any element located in the first layer, that is, the display level of the target element is changed to the highest display level.

After the target element is migrated from the first layer to the second layer, the attribute parameter of the target element in the first layer needs to be kept unchanged. Specifically, according to the attribute parameter of the target element in the first layer, the target element is drawn in the second layer, and the target element is deleted from the first layer. And the size, shape, position and other parameters of the target element when the target element is migrated to the second layer are the same as those of the target element originally in the first layer.

When the user selects the triangle shown in fig. 5, as shown in fig. 6, since the triangle is currently in the first layer, the triangle is migrated from the first layer to the second layer, as shown in fig. 6, the same triangle is drawn in the second layer, and the triangle is deleted from the first layer, and the position of the triangle in the second layer is the same as the position of the triangle in the first layer. Since the display level of the second layer is higher than that of the first layer, the display level of the triangle migrated into the second layer is higher than that of the circle and the rectangle in the first layer. The display content of the canvas interface is a superposition result of the second layer and the first layer, so that the circle and the rectangle in the first layer are superposed with the triangle in the second layer, the triangle and the circle have an overlapping position, the triangle is covered on the circle, and the triangle and the rectangle have an overlapping position, so the triangle is also covered on the rectangle.

S404, receiving element modification operation on the canvas interface, and correspondingly modifying the target element in the second layer according to the element modification operation.

In this embodiment, after the target element is displayed as the highest display level in the canvas interface, it indicates that the user has successfully selected the target element, and then the user inputs an element modification operation on the canvas interface, and accordingly, the intelligent interaction tablet may receive the element modification operation on the canvas interface, and generate an element modification instruction according to the element modification operation, and because the target element is currently in the second layer, the target element in the second layer is modified according to the element modification instruction. And the target element is modified on the second layer, so that the display level of the target element can be kept to be the highest display level, and other elements cannot be influenced currently.

As shown in fig. 7, an element modification operation is used as an element moving operation, for example, a user performs a dragging operation on the triangle to change the position of the triangle, and then the position of the triangle is changed in the second layer according to the dragging track of the user. The position of the triangle in the second layer is moved, so the display level of the triangle in the moving process is higher than that of the circle and the rectangle in the first layer, and the display content of the canvas interface is the superposition result of the second layer and the first layer, so the triangle still remains to be covered on the circle and the rectangle in the moving process.

S405, receiving a modification confirmation operation on the canvas interface, migrating the modified target element from the second layer to the first layer according to the modification confirmation operation, and changing the display level of the modified target element into the first display level in the first layer.

In this embodiment, when the user does not modify the target element any more, the user inputs a modification confirmation operation on the canvas interface, and accordingly, the intelligent interactive tablet may receive the modification confirmation operation on the canvas interface, generate a modification confirmation instruction according to the modification confirmation operation, migrate the modified target element from the second layer to the first layer according to the modification confirmation instruction, and change the display hierarchy of the modified target element to the original first display hierarchy in the first layer, thereby completing the modification of the target element, and the display hierarchies of a plurality of elements after the modification of the target element and the display hierarchy before the modification remain unchanged.

After the modified target element is migrated from the second layer to the first layer, the attribute parameter of the modified target element in the second layer needs to be kept unchanged. Specifically, according to the attribute parameter of the modified target element in the second layer, the modified target element is drawn in the second layer, and the modified target element is deleted from the second layer. And the parameters such as the size, the shape, the position and the like of the modified target element when the modified target element is migrated to the first layer are the same as the parameters such as the size, the shape, the position and the like of the modified target element in the second layer.

In a possible implementation manner, before performing the above S403, a display hierarchical order of the plurality of elements in the first layer is further obtained. Accordingly, one possible implementation manner of performing the above-mentioned change of the display hierarchy of the modified target element in the first layer to the first display hierarchy in S405 is as follows: and changing the display level of the modified target element into a first display level in the first layer according to the display level sequence of the plurality of elements. Specifically, after the modified target element is drawn into the first layer, it is also necessary to keep the display hierarchical order of the plurality of elements as the previous display hierarchical order, and therefore, according to the previously acquired display hierarchical order of the plurality of elements in the first layer, it may be determined that the display hierarchical order of the target element before modification is the first display hierarchical order, and therefore, the display hierarchical order of the target element after modification is the same as the display hierarchical order of the target element before modification, so that the display hierarchical order of the target element after modification is changed into the first display hierarchical order.

Optionally, according to the display hierarchy order of the multiple elements, one possible implementation manner of changing the display hierarchy of the modified target element in the first layer to the first display hierarchy is as follows: determining at least one element with a display level higher than the target element according to the display level sequence of the plurality of elements; and redrawing at least one element in the first layer according to the sequence of the display hierarchy of the at least one element from low to high. Specifically, at least one element with a display level higher than that of the target element before modification is determined according to the display level sequence of the plurality of elements, and since the display level of the element drawn later is higher than that of the element drawn earlier, the at least one element is redrawn in sequence in the first layer according to the sequence of the display level of the at least one element from low to high. Since the at least one element is redrawn in the first layer after the modified target element, the at least one element is higher than the modified target element, so that the display hierarchical order of the elements before the modification of the target element and the display hierarchical order of the elements after the modification of the target element are not changed.

As shown in fig. 8, when the user moves the triangle to the desired position, the user may lift the hand touching the triangle, and the touch operation of the user on the screen interface changes, and accordingly, the intelligent interactive interface detects that the touch operation of the user disappears, which is equivalent to receiving a modification confirmation operation of the user on the screen interface. And generating a modification confirmation instruction according to the modification confirmation operation, and migrating the triangle after the movement position in the second layer to the first layer in the canvas interface according to the modification confirmation instruction. As shown in fig. 8, the same triangle after being moved is drawn in the first layer, and the triangle is deleted from the second layer, and the position of the triangle in the first layer is the same as the position of the triangle after being moved in the first layer. According to the display level sequence of the circle, the triangle and the rectangle originally in the first layer, namely the display level of the circle is lower than that of the triangle, and the display level of the triangle is lower than that of the rectangle. Since the triangle after the position shift is drawn in the first layer, the display level of the triangle at the current position shift is higher than those of the circle and the rectangle, and therefore, the display level of the triangle after the position shift needs to be adjusted. And then according to the fact that the display level of the rectangle is originally higher than that of the triangle, redrawing the same rectangle in the first image layer, and enabling the display level of the redrawn rectangle to be higher than that of the triangle after the position is shifted. As the display content of the canvas interface is the superposition result of the second layer and the first layer, and the elements in the second layer are empty, the display content of the picture interface is the elements in the first layer, as shown in fig. 8, the rectangle covers the triangle after the movement position, and after the position of the triangle is obtained, the display hierarchy of the triangle is higher than the display hierarchy of the circle, and the display hierarchy of the rectangle is higher than the display hierarchy of the triangle.

In the control method of the intelligent interactive tablet provided by this embodiment, when it is determined that a user needs to modify a target element displayed in a canvas interface, the target element is drawn into a second layer with a high display level, and other elements are located in a first layer with a low display level; and then modifying the target element in the second layer according to the modification operation of the user, after the modification, migrating the modified target element from the second layer to the first layer, and changing the display level of the modified target element in the first layer into the display level before the modification, so that the display levels of the elements before and after the modification of the target element are the same, and the original drawing effect is not influenced. And because the display hierarchy of the second layer is higher than that of the first layer, in the process of modifying the target element, the display hierarchy of the target element is kept higher than those of other elements, and other elements with display hierarchies higher than the original display hierarchy of the target element do not need to be concerned. After the target element is modified, the display hierarchy of each element is changed into the original display hierarchy, so that the processing resource can be saved, and the performance can be improved. The user mainly concerns about the modified result, and in the process of modifying the target element, the user does not concern about the display hierarchical sequence of each element so that the user experience is not reduced.
