The selection mode is that the handwriting which is touched by the user and passes through the track or is in the circle is selected, and operations such as moving, zooming and the like can be carried out. In the erasing mode, an eraser appears when a user touches the area, and handwriting passing by the eraser track is erased.

In the process of using the whiteboard, other types of elements such as pictures may need to be displayed, a user may open a picture browser or other software to display the pictures and the other types of elements, but when the user opens a plurality of software, only one software is displayed at the front end of the screen to interact with the user, and the other software is shielded, so that the effect of displaying the pictures and writing at the same time cannot be achieved, and the user needs to switch handwriting and picture operations between the two software, which is tedious.

Some existing whiteboard software supports the function of inserting other elements, but the insertion of other elements can be performed only by switching from a writing mode to a selection mode, and the operation of the elements generates conflict with the action of generating handwriting by the touch of a user, that is, the whiteboard is difficult to recognize whether the touch of the user is to be written or control the inserted other elements, for example, fig. 1 is a schematic diagram of inserting a picture on the whiteboard, and when a touch point of the user falls on the position of the picture and moves to the left, the whiteboard is difficult to determine whether the user is to move the picture or write.

Aiming at the problem that the control operation of elements conflicts with the operation of generating handwriting by touching of a user when other types of elements are inserted into the whiteboard in the prior art, no effective solution is provided at present.

Example 1

In accordance with an embodiment of the present application, there is provided an embodiment of a control method for an intelligent interactive tablet, it should be noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer executable instructions, and that while a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than here.

Fig. 2 is a flowchart of a control method of an intelligent interactive tablet according to an embodiment of the present application, and as shown in fig. 2, the method includes the following steps:

step S202, receiving a touch operation on the whiteboard application interface, and acquiring the type of the touch operation, wherein the type at least comprises: a writing operation for writing on the whiteboard application interface and a selection operation for selecting an element on the whiteboard application interface.

Specifically, the whiteboard application interface is an operation interface provided by the whiteboard application, and can perform full-screen operation or reduce the operation to a window with a certain size. The touch operation on the whiteboard application interface may be an operation performed on the whiteboard application interface by touching the touch screen with a finger, or a touch operation generated on the whiteboard application interface by an electromagnetic pen or other writing equipment.

After receiving the touch operation, the type of the operation is determined first, and how to respond to the touch operation is determined. In the above scheme, it is necessary to determine whether the received touch operation is a writing operation or a selecting operation, so as to determine whether to generate writing on the whiteboard application interface or select other elements on the whiteboard application interface.

As an optional embodiment, a plurality of elements are opened on a whiteboard application interface, the whiteboard application interface includes a writing layer for bearing writing content and a plurality of element layers for bearing elements, and obtaining the type of the touch operation includes:

step S2021, when the touch operation is generated on the writing layer, acquiring a touch operation with a time length of the initial position being greater than or equal to a preset time length as a selection operation, and acquiring a touch operation with a time length of the initial position being less than the preset time length as a writing operation.

Step S2023 acquires the touch operation as the selection operation when the touch operation is generated on the element layer.

Specifically, the touch operation in which the time length of the initial position staying is greater than or equal to the preset time length may be a long-time pressing operation, and the touch operation in which the time length of the initial position staying is less than the preset time length may be a clicking operation, a tapping operation, a sliding operation, and the like.

When the touch operation is generated on the writing layer, if the touch operation is a long-press operation, the touch operation is a selection operation and is used for selecting other elements below the writing layer. When the touch operation is not the long press operation, if the writing layer is positioned on the top layer of the whiteboard application interface, writing is directly performed according to the touch operation, and if the writing layer is not positioned on the top layer of the whiteboard application interface, the writing layer is adjusted to the top layer of the whiteboard application interface and is directly written without the need that a user firstly selects the writing layer and then performs writing.

And when the touch operation is generated on the element layer, the touch operation is a selection operation, the element layer is selected according to the selection operation, and the element layer is adjusted to the top layer of the whiteboard application interface.

The element on the whiteboard application interface may be an element inserted in the whiteboard application interface. In an alternative embodiment, at least one layer can be inserted into the current whiteboard application interface through the detected insertion instruction. Specifically, the element to be inserted may be a picture, a text, or the like, or may also be an audio file, and if the element is an audio file, the displayed element may be a control icon for controlling audio playing or stopping.

Taking a whiteboard application as an example, fig. 3a is a schematic diagram of layers in a whiteboard application interface, and as shown in fig. 3a, when no other element is inserted into the whiteboard application interface, the whiteboard includes two layers, that is, a whiteboard background on the 0 th layer and a writing plane on the 1 st layer, the writing plane is located above the whiteboard background, the whiteboard background mainly determines a background color of the whiteboard, the writing plane mainly bears writing operations of a user, and a writing trace on the writing plane generates writing traces. At this point, a straight line is drawn on the whiteboard, and the effect shown in fig. 3b is obtained.

Still taking a whiteboard application as an example, fig. 4a is a schematic diagram of layers in another whiteboard application interface, where 4a can be obtained by inserting a picture 1 into fig. 3a, and a front effect diagram of the whiteboard application interface is shown in fig. 4b, after the picture 1 is inserted into a writing plane, the whiteboard currently includes three layers, that is, a whiteboard background on a 0 th layer, a writing plane on a 1 st layer, and a picture on a 2 nd layer.

And S204, when the touch operation is writing operation, generating writing handwriting according to the touch operation.

As an alternative embodiment, when the touch operation is a writing operation, generating handwriting according to the touch operation includes:

and step S2041, when the writing layer is located on the top layer of the whiteboard application interface, generating writing handwriting according to the writing operation.

And step S2043, when the element layer is positioned on the top layer of the whiteboard application interface, displaying the writing layer on the top layer, and generating writing handwriting according to the writing operation.

Specifically, the touch operation is generated in the writing layer, and is used for indicating that a first point (namely a down point) falling from the touch operation is in the writing layer, and when the touch operation falls, if the writing layer is positioned on the top layer of the whiteboard application interface, writing handwriting is directly generated according to the writing operation; and if the writing layer is not positioned at the top layer of the whiteboard application interface, namely the element layer is positioned at the top layer of the whiteboard application interface, displaying the writing layer at the top layer, and generating writing handwriting according to the writing operation.

And step S206, when the touch operation is a selection operation, adjusting the hierarchy of the element selected by the selection operation in the whiteboard application interface according to the selection operation.

As an alternative embodiment, when the touch operation is a selection operation, adjusting, according to the selection operation, a hierarchy of an element selected by the selection operation in the whiteboard application interface includes: and displaying the element layer selected by the selection operation on the top layer of the whiteboard application interface.

When the touch operation is generated in the element layer, the touch operation is a selection operation. Next, the hierarchical adjustment of the element layers is described according to different selection operations, where the element layer selected by the selection operation is used as a target layer.

In the first case, the selection operation is a tap operation, and the selected target layer is located on the writing layer. In this case, the target layer is directly adjusted to the top layer of the whiteboard application interface.

This is explained below with reference to several figures. Fig. 5a is a schematic diagram of a bitmap writing layer with multiple element layers according to an embodiment of the present application, and fig. 5b is a display effect diagram of fig. 5a, where the uppermost element is picture 3, and a selection operation falls on an element layer other than any picture 3, which triggers a hierarchical transformation. As described in detail below.

Fig. 5c is a schematic view of a hierarchy of the clicked picture 1 in the example shown in fig. 5a, fig. 5d is a display effect diagram of fig. 5c, and in combination with fig. 5c and fig. 5d, after the user clicks the picture 1, a selection operation falls within the picture 1, the picture 1 is switched to the top layer, and other layers descend in sequence.

By means of the scheme, other elements are inserted into the writing plane, so that after the previously inserted element layer is covered by the new element layer, the previously inserted element layer can be adjusted to the top layer again through the operation, and therefore a user can continue to display the previously inserted element layer after inserting the new element layer conveniently. In the application process, when the element layer to be displayed is not positioned on the top layer, the user can touch or slide the layer to be displayed conveniently, the element layer to be displayed can be switched to the current top layer, and the operation is very convenient.

In the second case, the selection operation is a long-press operation, and the selected target layer is positioned below the writing layer. In this case, the target layer is still adjusted to the top layer of the whiteboard application interface.

Fig. 6a is an operation diagram illustrating an operation of changing a layer hierarchy according to an embodiment of the present application, and fig. 6b is a display effect diagram corresponding to fig. 6 a. With reference to fig. 6a and 6b, the writing plane is located above the picture 1, and in order to adjust the picture 1 to the top layer, the user can press for a long time (for example, at the position 60 shown in fig. 6 a) in an arbitrary area where the picture 1 is located, so as to determine that the layer of the picture 1 is the target layer, and further, the layer where the picture 1 is located can be adjusted to the top layer, so as to obtain the display effect in fig. 4b, where the changed layers include the whiteboard background of the 0 th layer, the writing plane of the 1 st layer, and the picture 1 of the 2 nd layer.

Fig. 7a is a schematic diagram of another modified layer hierarchy according to an embodiment of the present application, and fig. 7b is a display effect diagram of fig. 7a, which is shown in conjunction with fig. 7a and 7b, in this example, three element layers are all below a written layer. Fig. 7c is a schematic diagram of a long press operation performed on the basis of fig. 7b, and fig. 7e is a display effect diagram of fig. 7 d. The user performs a long press operation at the position 70 shown in fig. 7c, after the device detects the operation, the device determines that the target layer is the 1 st layer where the picture 1 is located and the 2 nd layer where the picture 2 is located, switches the 1 st layer and the 2 nd layer as a whole to the top layer, and obtains the hierarchical relationship shown in fig. 7d after switching to the top layer (the display effect diagram is shown in fig. 7 e), where the hierarchical relationship between the picture 1 and the picture 2 is not changed, that is, the picture 1 is still at the next layer of the picture 2, but both the picture 1 and the picture 2 are located above the picture 3 and the writing plane.

As an optional embodiment, after displaying the element layer selected by the selection operation on the top layer of the whiteboard application interface, the method further includes:

in step S2061, the drag operation is received, and the element selected by the drag operation is moved according to the drag trajectory of the drag operation.

Specifically, the dragging operation may be a sliding operation performed on the element layer on the top layer, and the element on the element layer selected by the dragging operation is the element selected by the dragging operation.

Fig. 8a is a schematic diagram of a dragging element according to an embodiment of the present application, as shown in fig. 8a, a dragging operation selects a picture 3, and the dragging operation slides to the left, so as to move the picture 3 to the left.

In step S2062, a zoom operation is received, and the element selected by the zoom operation is zoomed according to the zoom operation.

Specifically, the scaling operation is used to enlarge or reduce the element, and four corners of the top element layer may be selected to scale the element.

Fig. 8b is a schematic diagram of a zoom element, as shown in fig. 8b, a picture 3 is selected by a selection operation, and the zoom operation enlarges the selected picture 3 at the upper right corner.

Step S2063 receives the deletion operation, and removes the element selected by the deletion operation from the whiteboard application interface according to the deletion operation.

Specifically, the deletion operation is used to delete the element from the whiteboard application interface. The menu corresponding to the element may be triggered to delete the element, or the element may be dragged to a preset position of the whiteboard application interface to delete the element.

Fig. 8c is a schematic diagram according to a deletion element, as shown in fig. 8c, the whiteboard application interface includes a deletion area, and after selecting the selected picture 3, the picture 3 can be deleted by dragging the selected picture to the deletion area in the whiteboard application interface.

As can be seen from the above, in the above embodiments of the present application, a touch operation on a whiteboard application interface is received, and a type of the touch operation is obtained, where the type at least includes: a writing operation for writing on the whiteboard application interface and a selecting operation for selecting an element on the whiteboard application interface; when the touch operation is writing operation, generating writing handwriting according to the touch operation; and when the touch operation is the selection operation, adjusting the hierarchy of the element selected by the selection operation in the whiteboard application interface according to the selection operation. According to the scheme, the type of the touch operation is acquired after the touch operation is received, so that the corresponding action can be executed according to the type of the touch operation, the technical problem that the control operation of the element conflicts with the operation of handwriting generated by the touch of a user when the whiteboard inserts other types of elements in the prior art is solved, and the element on any layer can be controlled by the user through adjustment of the layer, so that the effect of convenience in operation is achieved.

Specifically, the body on which the touch operation is performed refers to a body on which a first point, i.e., a down point, is located at which the touch operation is dropped. When the down point falls into the element layer, determining that a main body acted by the touch operation is the element layer; and when the down point falls into the writing layer, determining that the main body acted by the touch operation is the writing layer.

And when the touch operation is generated on the element layer, the touch operation is a selection operation, the element layer is selected according to the selection operation, and the element layer is adjusted to the top layer of the whiteboard application interface. When the touch operation is applied to the written image layer, further judgment is carried out according to the stay time of the touch operation at the initial position.

When the touch operation is generated on the writing layer, if the touch operation is a long-press operation, the touch operation is a selection operation and is used for selecting other elements below the writing layer. When the touch operation is not long press operation, if the writing layer is positioned on the top layer of the whiteboard application interface, writing is directly performed according to the touch operation, and if the writing layer is not positioned on the top layer of the whiteboard application interface, the whiteboard application adjusts the writing layer to the top layer of the whiteboard application interface and directly performs writing without selecting the writing layer by a user and then performing writing.

Specifically, the touch operation is generated in the writing layer, and is used for indicating that a first point (namely a down point) falling from the touch operation is in the writing layer, and when the touch operation falls, if the writing layer is positioned on the top layer of the whiteboard application interface, writing handwriting is directly generated according to the writing operation; and if the writing layer is not positioned at the top layer of the whiteboard application interface, namely the element image layer is positioned at the top layer of the whiteboard application interface, displaying the writing layer at the top layer, and generating writing handwriting according to the writing operation.

Step S908, when the touch operation is a selection operation, adjusting a level of an element selected by the selection operation in the whiteboard application interface according to the selection operation.

It should be noted that the above hierarchical relationship is embodied as the vertical height of a certain view under different systems, for example, in an android system, the height of the view in the vertical direction (i.e., the Z-axis height) may be set to determine the display relationship of the view, and a view with a large vertical height may block a view with a small vertical height and preferentially obtain a touch event response. Altering the hierarchy refers to modifying the vertical height of the view.

And step S9083, the target graph layer is placed on the top layer of the whiteboard application interface.

And step S9085, reducing the element layer with the layer level higher than the target layer by one layer.

When the touch operation is generated in the element layer, the touch operation is a selection operation. In the above scheme, the selection operation falls in any element layer on the upper layer of the writing layer, the selection operation may be a tap operation, and the selected target layer is on the writing layer. In this case, the target layer is directly adjusted to the top layer of the whiteboard application interface, and the element layer higher than the target layer is reduced by one layer.

For example, if the highest hierarchy is t, the hierarchy of the layer hit by the first type of operation is i (0< i < t), and there are m elements with hierarchies greater than i, the hierarchy of the layer hit by the first type of operation is set to t, 1 is subtracted from each of the hierarchies of the m element layers with hierarchies greater than i, and no processing is performed on the element layers with hierarchies less than i.

step S9087, when the element layer below the writing layer is selected by the selecting operation, acquiring a first element layer hit by the selecting operation and a second element layer higher than the first element layer.

And step S9089, arranging the levels of the first element layers in an ascending order to obtain a first array, and arranging the levels of the second element layers in an ascending order to obtain a second array.
