Please refer to FIG. 1 , which provides a schematic diagram of a mind map adjustment scene according to the embodiment of the present application. As shown in Figure 1, the first mind map set by the user can be displayed on the display screen of the terminal device used to implement the method, by obtaining the node that the user selects to move on the first mind map, for example: select " The three nodes "Branch Topic 2", "Sub Topic 3" and "Sub Topic 4" are used as moving nodes, and the selected nodes will be prompted, such as "Branch Topic 2", "Sub Topic 3" and "Sub Topic 4" Check the prompt next to the three nodes; then control the node to move into the adsorption area, and connect the node with the corresponding adsorption node in the adsorption area. ", move "Branch Topic 2", "Sub Topic 3" and "Sub Topic 4" from their original positions to the dotted rectangular box of "Branch Topic 3", because "Branch Topic 2" is " The parent node of "Subtopic 3" and "Subtopic 4", then "Branch Topic 2" hides the child nodes "Subtopic 3" and "Subtopic 4" during the moving process, and only displays the parent node "Branch Topic 2" ;When "Branch Topic 2" is close to "Branch Topic 3", the interface displays the adsorption area of "Branch Topic 3", that is, the dotted rectangle frame. "Branch Topic 3" for adsorption connection; after the connection between nodes is completed, the mind map adjustment device adjusts the position and size of all nodes on the first mind map, for example: reduce the "Branch Topic 1" and "Branch Topic 3" ", reduce the height of "Branch Topic 2", and keep the height of "Branch Topic 2" consistent with "Subtopic 1", "Subtopic 5", etc. Target node, control the target node to move according to the mobile operation. If the target node is within the range of the first adsorption area of the adsorption node, the target node will be adsorbed to the adsorption node, and the mind map will be updated.

Based on the schematic diagram of the scene shown in FIG. 1 , the method for adjusting the mind map provided by the embodiment of the present application will be described in detail below in conjunction with FIGS. 2 to 9 .

Please refer to FIG. 2 , which provides a schematic flowchart of a method for adjusting a mind map according to an embodiment of the present application. As shown in FIG. 2 , the method in this embodiment of the present application may include the following steps S101-S107.

S101. In the application interface, receive a first touch operation;

Specifically, in the application interface of the interactive tablet, the first touch operation triggered in the application interface can be monitored in real time, and the first touch operation can be an operation track generated by the user using a finger, a stylus, etc. in the application interface , can be used for writing in the application interface, or setting nodes in the first mind map displayed on the application interface, etc.

S102. Confirm that the first touch operation is a writing operation, and write corresponding handwriting in the application interface;

Specifically, if the first touch operation is a writing operation, for example: the first touch operation is a touch operation outside the area where the first mind map is located in the application interface, then it can be determined that the first touch operation is a writing operation, It can be understood that a third adsorption area is set for the first mind map, and the third adsorption area may be the adsorption area of the first mind map. If a node exists in the third adsorption area, it means that the node belongs to the first mind map. For the nodes in the mind map, the third adsorption area is used to divide the area where the first mind map is located in the application interface, and other areas except the first mind map. When the first touch operation does not fall within the range of the third adsorption area, it is determined that the first touch operation is a writing operation; otherwise, the first touch operation is determined as a node selection operation for the first mind map.

After confirming that the received first touch operation is a writing operation, the handwriting corresponding to the writing operation can be displayed in the application interface. The display method of the handwriting can be displayed following the writing operation, or it can be displayed on the recorded track after the writing operation is completed. One-time display, the specific display method can be set according to the actual situation. In addition, during the writing process, if the writing operation falls into the third adsorption area, the corresponding handwriting will be generated above the first mind map. After writing, the handwriting and the first mind map are independent elements, which can be separated Make adjustments, for example, when the handwriting is selected for movement, the first mind map remains unchanged, and vice versa.

S103, confirming that the first touch operation is a node selection operation for the first mind map, and obtaining the selected target node in the first mind map based on the node selection operation;

Specifically, in the application interface of the interactive tablet, if the first touch operation is a node selection operation, for example: the first touch operation is a touch operation in the area where the first mind map is located in the application interface, then it can be determined The node selection operation performed on all nodes included in the first mind map, the first mind map refers to the mind map set by the user, and the node selection operation refers to the operation of selecting nodes. It can be understood that, The mind map is displayed in the application interface of the interactive device such as the whiteboard application. If the user wants to adjust the position of the node in the mind map in the interactive application interface, he needs to select the selection node in the first mind map in the interactive device, and then select Selected nodes for operation processing.

There can be multiple branches in the first mind map, each branch can have multiple nodes, and each node is attached to the branch to form a parent-child node relationship, that is, the first node on the same branch can be the parent node of the second node, and the first node on the same branch can be the parent node of the second node. The second node can be a child node of the first node. If a node has only child nodes without a parent node, the node is determined to be the root node. At the same time, if a node has no parent node and child nodes, the node is determined to be the root node; if the target node is located at If there are two or more nodes on the same branch, there must be at least a pair of parent-child relationships. As shown in Figure 1, "root node", "branch topic 1" and "child topic 1" are located on the same branch, and "root node " is the parent node of "Branch Topic 1", and "Branch Topic 1" is the parent node of "Subtopic 1".

When the user needs to adjust the position of the node in the first mind map, obtain the selected node that needs to be moved in the first mind map, that is, select the target node; the target node can be one node or multiple nodes; Optionally, the target node can be a node of the same branch, or a node of a different branch, that is, the target node can be the first node, or a child node of the first node and the first node, or the first node and the second node, may also be child nodes of the first node and the second node, etc.

S104, acquiring a move operation for the target node;

Specifically, the mind map adjustment device obtains the movement operation for the target node, and controls the target node to move according to the movement operation; the movement operation can be a sliding operation of the user's finger or stylus on the mind map adjustment device, or it can be The finger click operation on the thinking path adjustment device, etc.; the target node moves according to the movement operation, which can be the target node moves according to the movement direction of the movement operation and the preset movement speed; optional, the mind map adjustment device can be real-time Display or delay display the moving process of the target node.

S105, move the target node based on the move operation, and during the movement process, display the removal style of the target node at the initial position of the target node, and display the preview style of the target node following the move operation;

Specifically, the mind map adjustment device obtains the initial position of the target node in the first mind map. The initial position refers to the position before the target node is moved. Obtaining the initial position can observe the position change process of the target node; The move operation of the target node generates the removal style and preview style of the target node. The removal style refers to the preview result of the target node that is always at the initial position during the movement; the preview style refers to the connection between the preview target node and the adsorption node The pattern of the effect, the mind map adjusts the initial position of the device in the first mind map to generate the removal style of the target node;

The target node that the user moves is the preview style of the target node. The preview style refers to the preview result of the target node that follows the movement during the movement process. It can be understood that the preview style can be the preview result of multiple nodes and connection relationships. There may be multiple sub-nodes hidden, and moving by operating the preview style can make the picture of the moving process more concise. When the preview style is moved, the removed style of the target node is displayed at the initial position; when the preview style reaches the adsorption area of the adsorption node, the preview style can be adsorbed on the shape edge of the adsorption node, and the preview style and the adsorption node display connecting lines, such as As shown in Figure 1, "Branch Topic 2", "Subtopic 3" and "Subtopic 4" are target nodes, and "Branch Topic 3" is an adsorption node, while the preview style in Figure 1 only shows "Branch Topic 2", When "Branch Topic 2" is close to "Branch Topic 3", a connecting line is displayed between the two nodes.

S106, after the movement operation is finished, determine the first adsorption area of the end point of the target node, and determine the adsorption node corresponding to the first adsorption area, the adsorption node is any other node in the first mind map except the target node node;

Specifically, the mind map adjustment device obtains the coordinate position of the target node after moving as the end position, and determines the adsorption area where the node position is based on the preview style as the first adsorption area, and determines the end point position of the target node after the movement operation is completed. The first adsorption area at , determine the adsorption node corresponding to the first adsorption area, and display the target node at the end position, wherein the adsorption node is any other node in the first mind map except the target node.

S107. Determine a first association relationship between the target node and the adsorption node;

Specifically, based on the node position of the target node, the first association relationship between the target node and the adsorption node is determined. The first association relationship refers to the connection relationship between the target node and the adsorption node. If the adsorption node has no child nodes, the target node is the child node of the adsorption node; if the adsorption node has child nodes, determine the positional relationship between the target node and the child nodes of the adsorption node.

S108. Perform adjustment processing on the first mind map based on the first association relationship, eliminate the removal style and the preview style, and display a second mind map obtained after the adjustment process;

Specifically, the mind map adjustment device adjusts the first mind map based on the association relationship to obtain the second mind map. It can be understood that after the nodes in the first mind map are moved, the positions between nodes The relationship will change. There is no node at the position before the target node is moved, and new nodes are added at the position after the target node is moved. The distribution of nodes with different spacing affects the beauty of the mind map. Therefore, it is necessary to perform adjustment processing on the first mind map. Adjust the node attributes of all nodes in the first mind map, the node attribute information includes at least one of node position, node size and node shape, and determine the adjusted first mind map as the second mind map, and Display the second mind map.

In the embodiment of this application, by selecting the target node whose position needs to be adjusted in the mind map, the target node is controlled to move according to the movement operation. When the target node is within the range of the first adsorption area of the adsorption node, the target node is adsorbed to the adsorption node , and update the mind map, you can adjust the node position through the set adsorption area and the association between the nodes, reduce the operational complexity of node position adjustment, and improve the efficiency of node position adjustment.

Please refer to Figure 3, which provides a schematic flow chart of a mind map adjustment method for the embodiment of the present application, which is used to further refine the embodiment shown in Figure 2, as shown in Figure 3, the method of the embodiment of the present application The following step S201-step S214 may be included.

In the embodiment shown in FIG. 2, step S103 specifically includes the following steps S201-S202:

S201, acquiring the operation mode for the first mind map in the application interface;

S202. Determine that the node selection operation satisfies the node selection method corresponding to the operation mode, then obtain the selected target node in the first mind map based on the node selection operation;

Specifically, the mind map adjustment device acquires the operation mode for the first mind map, and the operation mode is used to represent the operation mode of the mind map, and is specifically used to set different operation modes for selecting target nodes, and determine that the node selection operation satisfies the operation The node selection method corresponding to the mode is based on the node selection operation to obtain the selected target node in the first mind map; different modes of node selection are provided in different operation modes, which improves the flexibility of node selection.

If the operation mode is the writing operation mode, the node selection method is a long press operation, and the writing operation mode refers to adjusting the first mind map during the process of adding nodes, deleting nodes, etc. to edit the content of nodes in the first mind map The mode of operation in which the position and association relationship of the nodes in the Obtain the target node corresponding to the long-press operation. The long-press operation can be a touch object such as a stylus, a finger, and long-press the node to be selected in the first mind map for more than a fixed time. The fixed time can be set according to the demand, which is understandable Yes, long pressing a node for more than a fixed time can prevent the user from touching the node by mistake, resulting in wrong node selection. For example, after the first mind map acquires that the first node is long pressed for more than 2 seconds, the first node is determined to be the target node. Optionally, if the operation mode is the writing operation mode, then the input click operation is obtained in the first mind map, and the target node corresponding to the point operation is obtained, and the click operation can be at least one click on a touch object such as a stylus or a finger Nodes to be selected in the first mind map;

If the operation mode is the selection operation mode, the node selection method is the sliding operation, and the selection operation mode refers to the location where the first mind map adjusts the position and association relationship of the nodes in the first mind map after the content editing of the nodes is completed. mode of operation. Obtain the target node within the range of the sliding area of the sliding operation; the sliding operation can be a touch object such as a stylus, a finger touching a node during the sliding process in the first mind map, or clicking a single node, or simultaneously Click on multiple nodes, or draw a marquee containing the nodes in the first mind map, for example, touch the first node during the sliding operation mode of the first mind map, and confirm the first node as the target node.

It can be understood that the node selection operation in different operation modes can be customized and set, and this embodiment of the present application provides only an optional implementation manner. Optionally, when the first mind map is in the selection operation mode, content editing functions such as adding nodes and deleting nodes cannot be performed.

Optionally, based on the node selection operation, the selected target node is obtained in the first mind map, and the target node displays a selection prompt, which can be a rectangular box surrounding the target node, or a tick generated next to the target node. Prompt information that has the effect of distinguishing nodes such as selection symbols. If the selected node has child nodes, the child nodes will also be selected. As shown in Figure 4, in the writing operation mode, the stylus clicks on the "Branch Topic 1" node to obtain the "Branch Topic 1" node and its child nodes "Subtopic 1" and "Subtopic 2" as target nodes; As shown in Figure 5, in the selection operation mode, the nodes "branch topic 1" and "subtopic 3" touched by the stylus from position A to position B, so "branch topic 1", "subtopic 1" ”, “Subtopic 2” and “Subtopic 3” are determined as target nodes. Add selection prompts, preview styles, and remove styles to improve the user's interactive experience. The results of the adsorption can be displayed to the user, which is convenient for the user to determine the position of the node to move or adjust the position of the node to move.

In the embodiment shown in FIG. 2, before step S104, the following steps S203-S204 are specifically included:

S203, acquiring a second adsorption area corresponding to each node in the first mind map;

Specifically, the root node in the first mind map can have multiple branches, and each branch can have multiple nodes. The mind map adjustment device obtains the second adsorption area corresponding to each node on each branch, and the second adsorption The area refers to the area where the target node can be adsorbed with each node.

Optionally, the mind map adjustment device obtains the node position of each node on each branch in the first mind map, the second association relationship between each node and the vertical position of the center, based on the node position of each node, each The second association relationship among the nodes and the center vertical position of each node respectively determine the second adsorption area corresponding to each node.

The mind map adjustment device divides the first mind map into an XY coordinate system, the node position of the node includes the coordinate position of the node in the XY coordinate system, the second association relationship between each node includes the connection relationship between nodes, etc., the center The vertical position is the position set for the shape of the node, generally set at the midpoint of the bisector of the shape of the node, for example, if the shape of the first node is a rectangle, the vertical position of the center of the first node is located at the midpoint of the diagonal of the rectangle ; If the shape of the first node is a circle, then the center vertical position of the first node is located at the center of the circle.

It can be understood that, if a certain node is determined as the first node, the second adsorption region may be determined as the first adsorption region. In order to make the target node easily adsorb to the adsorption node, it is necessary to ensure that the range of the second adsorption area of each node is maximized. Therefore, the boundaries of the second adsorption area of two adjacent nodes can be close to each other or overlap, and adjacent The second adsorption area of two nodes has no intersection; if the second adsorption area of each node on each branch has intersection, it cannot be determined that the target node after moving is located in the adsorption node corresponding to the first adsorption area. Therefore, the first thinking There is no intersection between the second adsorption areas of any two nodes in the map;

To determine the second adsorption area corresponding to each node, it is necessary to determine whether the node is the root node. If the node is not the root node, then determine the positional relationship between the node and the root node; after determining the positional relationship between the node and the root node, determine whether the node has A node is determined based on the judgment result to correspond to the second adsorption area.

If the first node is the root node, the first node has two second adsorption areas. The second adsorption area in the positive direction of the X axis is defined as the X positive second adsorption area, and the steps of determining the X positive second adsorption area are the same as determining "the first node is located in the positive direction of the X axis of the root node, and the first node does not have children The steps of the second adsorption area of node" are the same; the second adsorption area in the negative direction of the X axis is defined as the X negative second adsorption area, and the steps of determining the X negative second adsorption area are the same as determining "the first node is located at the root node X In the negative direction of the axis, and the first node has no child nodes", the steps of the second adsorption area are the same.
