Embodiment 1

[0056] see figure 1 , figure 1 It is a schematic flowchart of a learning video-based formula questioning method disclosed in an embodiment of the present invention. Such as figure 1 As shown, the formula questioning method based on the learning video may include the following steps:

[0057] 101. During the playback of the learning video, the learning device detects whether the user triggers the formula search command, and if so, execute step 102; if not, end this process.

[0058] In the embodiment of the present invention, the playback interface of the learning video can include the video content being played, and a menu bar, which can include but not limited to a play button, a pause button, a fast-forward button, a back button, and a progress bar for learning video playback , and the search formula button, etc. The user can trigger the formula search instruction by clicking the formula search button, or the user can also search for formulas in other ways such as voice co...

Embodiment 2

[0081] see figure 2 , figure 2 It is a schematic flowchart of another learning video-based formula questioning method disclosed in the embodiment of the present invention. Such as figure 2 As shown, the formula questioning method based on the learning video may include the following steps:

[0082] 201. During the playing process of the learning video, the learning device detects whether the user triggers the formula search instruction, and if so, execute step 202; if not, end this process.

[0083] 202. The learning device judges whether there is a formula in the target screen played at the current moment of the learning video. If yes, execute steps 203 to 207. If no, end this process.

[0084] 203. The learning device outputs at least one formula marked box, where each formula marked box contains a formula.

[0085] In the embodiment of the present invention, the target formula includes at least a mathematical formula.

[0086] In the embodiment of the present invent...

Embodiment 3

[0106] see image 3 , image 3 It is a schematic flowchart of another learning video-based formula questioning method disclosed in the embodiment of the present invention. Such as image 3 As shown, the formula questioning method based on the learning video may include the following steps:

[0107] 301. During the playback of the learning video, the learning device detects whether the user triggers a formula search instruction, and if so, execute step 302; if not, end this process.

[0108] 302. The learning device judges whether there is a formula in the target screen played at the current moment of the learning video. If yes, execute steps 303 to 308. If no, end this process.

[0109] In the embodiment of the present invention, the target formula includes at least a mathematical formula.

[0110]303. The learning device outputs at least one formula marked box, where each formula marked box contains a formula.

[0111] 304. The learning device detects a target formula ma...

Abstract

A method for asking questions about a formula based on a learning video and a learning device, comprising: during the playback of the learning video, detecting whether a user triggers a formula search command; Whether there is a formula in the target picture played at any time; when it is judged that there is a formula in the target picture, the analysis corresponding to the target formula is output. By implementing the embodiment of the present invention, it is possible to quickly search for formulas in learning videos.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a method for asking questions about formulas based on a learning video and a learning device. Background technique [0002] Currently, students can learn by watching learning videos. For example, students can learn mathematics by watching learning videos about mathematics. During the process of watching the learning video, students often need to search for a certain content in the learning video. In particular, when the content that students need to search is a formula, it is difficult to ask questions about the formula orally or in writing, which makes it difficult to search for the formula in the learning video. It can be seen that how to quickly search the formulas in the learning video has become an urgent problem to be solved. Contents of the invention [0003] The embodiment of the present invention discloses a learning video-based formula questioning metho...
