Problems solved by technology

[0004] However, a shortcoming of the above-mentioned method is that since the accuracy of facial expression recognition still needs to be improved, and the user's facial expressions cannot really reflect the user's psychological activities sometimes, it is easy to cause the playback adjustment to be adjusted entirely through facial expression recognition. It is not accurate, and if users want to cancel the adjustment, they often need to manually rewind the video and restore the past video playback speed. Backtracking to the original video timing and original video playback speed, which prevents users from continuing to complete the course in an optimal manner

Embodiment Construction

[0036] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0037] Such as figure 1 As shown, the present embodiment proposes a method for playing video lessons based on user interaction, including the following steps:

[0038] 1) Play the teaching course video and capture the user's expression information at the same time;

[0039] 2) According to the expression information captured in step 1), the playback parameters of the teaching course video are automatically adjusted, specifically including:

[0040] 21) Determine whether the duration of the facial expression information captured in step 1) exceeds the prescribed threshold time (gener...

Abstract

The invention relates to a video course playback method based on user interaction. The method comprises the following steps of playing a teaching course video, and capturing expression information ofa user; according to the captured expression information, automatically adjusting a paly parameter of the teaching course video; and determining whether the user approves the adjusted play parameter,if not, restoring a previous play parameter and returning to capture expression information of the user, if yes, returning directly to capture expression information of the user. Compared with het prior art, the video course playback method based on user interaction has the advantages of being more interactive and more accurate.

Description

technical field [0001] The invention relates to the field of video course teaching, in particular to a method for playing a video course based on user interaction. Background technique [0002] With the rapid development of computer technology, online education has developed in full swing. The core of education is the transmission of knowledge, and the most direct way of transmission is video. More and more people choose to watch videos online for learning, but the only disadvantage of the online broadcast learning method and offline classroom learning is the lack of interaction, that is, there is no way to know the feedback of the students. [0003] Now that artificial intelligence has developed rapidly, using artificial intelligence can help us analyze and record the user's expression feedback during learning. By analyzing the user's expression, we can adjust the playback speed of the current video in real time and help users record the difficulties in the learning proces...
