In this embodiment, after the at least two first pictures are displayed on the display interface of the electronic whiteboard, the user may continue to perform a first input on the display interface, for example, a click input, a slide input, and the like, so as to generate an input mark on the display interface.
In combination with an actual application scene, when a teacher uses the electronic whiteboard, first pictures from terminal devices of a plurality of students can be displayed on a display interface of the electronic whiteboard in a split screen manner; the first picture can be the answering content of the student; in other words, the teacher can simultaneously display the answer contents of different students on the display interface of the electronic whiteboard, and then can write on the display interface (corresponding to the first input), and explain and comment on the accuracy of the answer contents and the goodness of the answer thought, so that the interaction effect of the course is improved, and the convenience of teaching is improved.
Similarly, for an office application scenario, users of different terminal devices may send performance, plans, and other contents to the electronic whiteboard in the form of pictures, and users of the electronic whiteboard may perform comparison, comment, and the like, and will not be described in detail herein.
Considering practical applications, the input mark may have a larger purpose, for example, the input mark may be a correct solution for teacher writing, or a subsequent task to be completed for arrangement, etc.; in this embodiment, a region of the electronic whiteboard for displaying the at least two first pictures and the input mark is subjected to screen capturing, so that the second picture simultaneously has contents corresponding to the at least two first pictures and the input mark; when the second picture is subsequently sent to the terminal equipment, the content of the interactive data can be increased, and the data interaction effect is improved.
Optionally, as shown in fig. 5, the step of generating an input mark on a display interface of the electronic whiteboard according to the first input includes:
and 503, after the preset time length, clearing the input mark generated on the second display area.
The following description of the present embodiment is also provided in connection with a practical application scenario:
under the application scene, the teacher displays the answering contents of different students on the display interface of the electronic whiteboard at the same time. Because the formats of the answering contents are generally similar, for example, the positions of the question stem, the answering area and the like are consistent; therefore, when the teacher explains and labels the answer content in one display area, the label can be expanded to the corresponding position in other display areas, so as to facilitate comparison.
Specifically, in this embodiment, after receiving the first input, the electronic whiteboard may determine the display area where the first input is located, that is, determine the first display area; the input mark is generated in the first display area in response to the first input, and meanwhile, the input mark is generated at the corresponding position (corresponding to the second display area) of other display areas, so that the effect of facilitating content comparison is achieved.
The second display area may be one or more display areas in the M display areas, and the specific number of the second display areas may be determined according to whether any display area displays the first picture. For example: in the M display regions, there may be 3 display regions including the first display region and displaying the first picture, and 1 display region does not display the first picture, and then the remaining 2 display regions except the first display region among the 3 display regions may be determined as the second display region. Of course, the determination method of the second display area is only illustrated here, and in practical applications, the determination method of the second display area may be selected as needed.
Further, the input mark displayed on the second display area can be automatically cleared after a preset time period elapses; therefore, on one hand, when a teacher explains the first picture displayed in the first display area, comparison explanation can be conveniently carried out, and the teaching effect is improved; on the other hand, the influence on the visual effect caused by displaying too many marks on the electronic whiteboard can be avoided, and the subsequent first input in the second display area is facilitated, and the visibility of the input marks is ensured.
