The implementation of the electronic note restoration method of the present application in the above application scenario will be described below with reference to specific embodiments.

Example 1

The electronic note reduction method disclosed by the embodiment of the application is applied to electronic equipment, and the electronic equipment is used as an interaction panel for explanation.

The following describes in detail the electronic note reduction method provided by the embodiment of the present application with reference to fig. 1 to 8.

Referring to fig. 1, the electronic note restoring method provided by the embodiment of the application includes the following steps:

Step S110: when writing on an electronic whiteboard writing page, responding to triggering recording operation of at least one group of first writing notes, and storing handwriting data corresponding to the first writing notes as note nodes; the handwriting data is used to record a writing process of the first written note.

When the electronic whiteboard is opened, a writing page is presented, and an operable area is arranged in the writing page, so that writing can be performed on the operable area. Alternatively, the first written note may be all the written contents on the electronic whiteboard before the triggering recording operation, and the first written note may also be the written contents on the electronic whiteboard between two adjacent triggering recording operations. The written content may include written text, erased text, inserted graphics, inserted forms, and the like.

It is to be understood that, when the first writing note may be all writing contents on the electronic whiteboard before the recording operation is triggered, the handwriting data corresponding to the first writing note is handwriting data corresponding to all writing contents on the electronic whiteboard, and further the handwriting data is stored as a note node, so that when the writing note is restored through the note node, the writing process of all writing contents on the electronic whiteboard before the recording operation is triggered is restored. As shown in fig. 2, for example, after first writing is performed on an electronic whiteboard, writing 1 will be generated, and when a first trigger recording operation is performed at this time, writing 1, which is handwriting data corresponding to all writing contents before the first trigger recording operation, is saved as a note node 1List; then, after the second writing is carried out on the electronic whiteboard, writing handwriting 2 is generated, and when the second triggering recording operation is carried out at the moment, writing handwriting data corresponding to all writing contents before the second triggering recording operation, namely writing handwriting 1 and writing handwriting 2, are stored as a note node 2List; finally, after the third writing is performed on the electronic whiteboard, writing 3 is generated, and when the third triggering recording operation is performed at this time, writing data corresponding to all writing contents before the third triggering recording operation, namely writing 1, writing 2 and writing 3, are stored as a note node 3List. Thereafter, note node 1List, note node 2List, and note node 3List are stored as note node set RecordList, which note node set RecordList is then stored to a database. When clicking the note node 1List, the note node 1List is found from the note node set RecordList in the database and put into the memory, and then the writing trace 1 in the note node 1List is read from the memory, so that the first writing process is restored on the electronic whiteboard. When clicking the note node 2List, the note node 2List is found from the note node set RecordList in the database and put into the memory, and then the writing 1 and the writing 2 in the note node 2List are read from the memory, so that the processes of first writing and second writing are sequentially restored on the electronic whiteboard. When clicking the note node 3List, the note node 3List is found from the note node set RecordList in the database, and put into the memory, and then the writing 1, the writing 2 and the writing 3 in the note node 3List are read from the memory, so that the processes of the first writing, the second writing and the third writing are sequentially restored on the electronic whiteboard.

It can be understood that, when the first writing note is writing content on the electronic whiteboard between two adjacent triggering recording operations, the writing data corresponding to the writing note is writing data corresponding to writing content on the electronic whiteboard between the triggering recording operations, and further the writing data is stored as a note node, so that when the writing note is restored through the note node, the writing content on the electronic whiteboard between two adjacent triggering recording operations is restored.

In one embodiment, since the nodes are triggered successively, in order to save the storage space of the note node, the first writing note is all writing contents on the electronic whiteboard before the triggering recording operation, but writing data corresponding to the first writing note is writing data corresponding to writing contents on the electronic whiteboard between two adjacent triggering recording operations, and further when the writing note is restored by the note node, writing data of all nodes before the note node are acquired, and writing data of the note node are sequentially read according to the triggering time sequence of the note node, so as to restore all writing contents on the electronic whiteboard before the triggering recording operation.

In one embodiment, the handwriting data includes a writing path of all handwriting corresponding to the first written note, corresponding writing coordinates, corresponding pressure values, and a display layer on the electronic whiteboard. And restoring the generation process of each handwriting of the first writing on the electronic whiteboard according to the writing paths, the corresponding writing coordinates, the corresponding pressure values and the display layers on the electronic whiteboard, so as to realize visual review of the generation process of the writing.

Step S120: responding to a trigger save operation of the writing page, and storing a second writing note displayed in the writing page and the note node in the writing page trigger record in an associated mode; wherein the first written note is a partial or complete note in the second written note generation process.

Wherein the first written note is a partial or complete note in the second written note generation process. In one embodiment, the second written note displayed may include the first written note; for example, after the writing page writes 1,2 and 3, the user performs trigger recording operation, and then determines 1,2 and 3 as a first writing note, and further stores the first writing note as a note node; and continuing to write 4,5 on the writing page, wherein the writing page displays 1,2,3,4,5, and if the user triggers a save operation on the writing page, a second writing note displayed in the writing page comprises 1,2,3,4,5, and obviously, the second writing note comprises the first writing note. In one embodiment, the displayed second writing note may also not include the first writing note, for example, after the writing page writes 1,2 and 3, the user performs a trigger recording operation, and then determines 1,2 and 3 as the first writing note, and further stores the first writing note as a note node; and then, erasing 1,2 and 3 on the writing page, and continuing to write 4 and 5 on the writing page, wherein the writing page displays 4 and 5, and if the user triggers the storage operation on the writing page, the second writing note displayed in the writing page is 4 and 5, and obviously, the second writing note does not comprise the first writing note corresponding to the note node.

In one embodiment, when the second writing note displayed on the writing page and the note node recorded by triggering the writing page are stored in an associated mode, the second writing note displayed on the writing page can be stored as a writing document to be stored in a database, the note node recorded by triggering the writing page is stored as note data corresponding to the writing document to be stored in the database, meanwhile, when the writing document is stored, the note data can be added in a storage path at the same time, and the writing document and the note document are stored in an associated mode, so that when the writing document is opened, handwriting can be triggered in the writing document by triggering the note node of the note document. It should be noted that, the written document and the note data are independent of each other and do not interfere with each other, that is, the written content in the written document does not affect the content of the note data. In one embodiment, handwriting data within the note node is persisted in a device storage system.

Step S130: and when the first writing note is restored on the electronic whiteboard, responding to the triggering opening operation of the writing page, and displaying a second writing note and a list of note nodes on the writing page.

In one embodiment, after the triggering and storing operation of the writing page, the writing page is stored in an interactive tablet according to a format preset by the electronic whiteboard, a second writing note displayed in the writing page and the note node recorded in the writing page triggering are stored in an associated mode, if the writing page is closed, an icon corresponding to the writing page is displayed on the interactive tablet, after the icon corresponding to the writing page is clicked, the opening operation of the writing page can be triggered, and the second writing note and the list of the note node are displayed on the writing page.

After the triggering and storing operation on the writing page, the writing page is stored in an interactive tablet according to a preset format of the electronic whiteboard, a second writing note displayed in the writing page and the note nodes recorded in the writing page triggering mode are stored in an associated mode, if the writing page is not closed, a list of the writing note nodes is displayed on the writing page, and further, when the triggering operation on the note nodes is responded, according to the handwriting data corresponding to the note nodes, the writing process of the first writing note is restored on the writing page to cover the second writing note.

Step S140: responding to the triggering operation of the note node, and restoring the writing process of the first writing note on the writing page according to the handwriting data corresponding to the note node so as to cover the second writing note.
