The thinking guide picture is an effective graphic thinking tool for expressing divergent thinking, which uses the skill of picture and text repetition, expresses the relationship of main bodies of all levels by hierarchical pictures which belong to the related each other, and establishes memory links between the subject keywords and the images, colors and the like. The thought-guide graph provides convenience for users to know the global content, but because the thought-guide graph is usually large and the nodes in the thought-guide graph are dense, the users are easily influenced by the contents of other nodes when viewing the local content, and the difficulty of viewing the local content by the users is increased.
For example, as shown in fig. 4, a thought-chart presentation page diagram of a slide shows, in which 3 thought-charts are displayed, each thought-chart includes multiple levels of nodes, for example, 11, 12, 13, 14 are the same level of nodes; 31. 32, 33, 34 are same level nodes. Optionally, the priority of the nodes in the same level may be the same, or may have a high priority order.
When the display page only comprises one mind map, after the page is entered, the mind map is defaulted as selected, and an expansion instruction can be sent to the target mind map directly by pressing a function key of the remote control equipment.
When the display page comprises a plurality of thinking diagrams, the thinking diagrams can be selected in sequence by pressing the function keys of the remote control equipment, the finally selected thinking diagram is determined as the target thinking diagram, and then the expansion instruction is sent to the target thinking diagram by pressing the function keys of the remote control equipment.
The method comprises the steps of sending an expansion instruction to the target thinking guide picture by pressing a function key of the remote control device, wherein the user can hold the remote control device by hand to face a square key on the single-machine remote control device in any direction without aiming laser emitted by the remote control device at the target thinking guide picture. Generally, the control range of the remote control device is 50-60 meters.

the expansion rule can be one-key expansion, gradual expansion or node-by-node expansion, one-key folding, gradual folding or node-by-node folding, and the like.
The unfolding rules corresponding to the unfolding process and the folding process can be respectively set, and if the unfolding rules are set to be gradually unfolded, the folding process is carried out by one key.
One possible implementation way is that the total node number of the target thinking graph and the currently expanded node number are obtained, and if the currently expanded node number is smaller than the total node number, the node expansion state is determined to be a non-complete expansion state; and if the number of the nodes which are unfolded currently is equal to the total number of the nodes, determining that the node unfolding state is a complete unfolding state.
Optionally, for the non-fully unfolded state, the unfolding and folding processes are included. Therefore, it is necessary to determine the previous node expansion state, and if the previous node expansion state is not the fully expanded state and the number of expanded nodes is reduced, it is necessary to fold the node at this time.
For example, the target mind map is currently in a non-fully-expanded state, and is also in a non-fully-expanded state last time and the number of expanded nodes increases in a manner of expanding and folding step by step, and then the nodes need to be expanded at this time.
S103, displaying the target mind map based on the node expansion state and according to the expansion rule.
In the concrete implementation, if the expansion rule is gradual expansion and one-key folding, when the current node expansion state is incomplete expansion, the next-level node is continuously expanded, and when the current node expansion state is complete expansion, all nodes are folded to the root node by one key.
If the expansion rule is one-key expansion and step-by-step respective folding, when the current node expansion state is incomplete expansion, the previous-level node is continuously folded, and when the current node expansion state is complete expansion, all nodes are expanded by one key.
The expansion rule may also be a permutation and combination of one-key expansion, gradual expansion or node-by-node expansion and one-key folding, gradual folding or node-by-node folding, and the corresponding expansion mode is not particularly limited.
In the embodiment of the application, in a thinking guide picture display page, an expansion instruction sent by a remote control device aiming at a selected target thinking guide picture is received, the node expansion state of the target thinking guide picture is obtained, a preset expansion rule is obtained, the node expansion state comprises a complete expansion state and a non-complete expansion state, and the target thinking guide picture is displayed according to the expansion rule based on the node expansion state. The display control of the thinking guide graph is realized by unfolding or folding the thinking guide graph on the remote control display interface of the remote control equipment, the display control is convenient and flexible, the controllability is good, the display control method is suitable for large-screen teaching scenes or teaching scenes leaving a display screen, and the teaching experience can be improved.
