Problems solved by technology

But since concentration is a person's conscious or unconscious attention, third parties are often difficult to detect
Existing teaching videos can only detect the viewer's understanding of the video content by setting the question plug-in, but cannot detect the concentration of the video viewer watching the video

Embodiment Construction

[0031] A device for detecting concentration of online video viewers provided in this embodiment has a structure such as figure 1 shown, including,

[0032] The video playing module is used to play the video; the video playing module includes a drag button, which is used for the viewer to drag and select the time point to watch the video. The drag button can be used to choose to watch the video repeatedly, which is convenient for viewers to watch multiple times and study hard;

[0033] Preset module: used to preset the number of embedded events during video playback and generate a comparison table of different response time and concentration scores, and divide the video into segments according to the number of embedded events;

[0034] Prompt module: for randomly generating the time of the pop-up embedded event during video playback and scoring different response times of viewers; the prompt module includes a time generating device for randomly generating pop-up embedded event...

Abstract

The invention discloses a method for detecting the attentiveness of an online video viewer. The method comprises the following steps of: (1) presetting the number of embedded events according to video playing time; (2) setting a compatable for different response time and corresponding scores; (3) segmenting a video according to the number of the embedded events; (4) randomly generating specific time at which the embedded events are popped up in each video segment in a video playing process; (5) popping-up an embedded event dialog box at the preset video playing time, and eliminating the dialog box according to a dialog box hint by the viewer; (6) computing a score of the video segment according to time from the popup to elimination of the dialog box; and (7) summarizing the scores of eachvideo segment, computing an average score of the scores of each video segment and storing the average score into a storage module. Simultaneously, the invention also discloses a device for detecting the attentiveness of the online video viewer. By the method and the device, the attentiveness of the video viewer is intuitively and accurately judged, and an effective supervision function is realized in web-based instruction.

Description

technical field [0001] The invention relates to a method for detecting concentration of an online video viewer, and more specifically relates to a method for installing a plug-in in a video player to judge the seriousness of the viewer, which belongs to the field of network video teaching. Background technique [0002] With the promotion of online teaching and the popularization of information technology, online video teaching, as one of the most effective means of online teaching, plays an increasingly important role in reducing the burden on teachers and helping students to study and review. However, the lack of effective learning process supervision in online teaching is the bottleneck of the development of online teaching. [0003] Most of the current online video teaching has no binding force on students, which has caused many students to fail to consciously study the content in the video, which is also the main reason why many people do not accept online video teaching...
