This paper describes a system developed to help University students get more from their online lectures, tutorials, laboratory and other live sessions. We do this by logging their attention levels on their laptops during live Zoom sessions and providing them with personalised video summaries of those live sessions. Using facial attention analysis software we create personalised video summaries composed of just the parts where a student's attention was below some threshold. We can also factor in other criteria into video summary generation such as parts where the student was not paying attention while others in the class were, and parts of the video that other students have replayed extensively which a given student has not. Attention and usage based video summaries of live classes are a form of personalised content, they are educational video segments recommended to highlight important parts of live sessions, useful in both topic understanding and in exam preparation. The system also allows a Professor to review the aggregated attention levels of those in a class who attended a live session and logged their attention levels. This allows her to see which parts of the live activity students were paying most, and least, attention to. The Help-Me-Watch system is deployed and in use at our University in a way that protects student's personal data, operating in a GDPR-compliant way.

在线实时缩放类的基于注意力的视频摘要

本文介绍了一种系统,该系统可以帮助大学生从在线讲座,教程,实验室和其他现场会议中获得更多收益。为此,我们在实时缩放会话期间将他们的注意力记录在笔记本电脑上,并为他们提供这些实时会话的个性化视频摘要。使用面部注意力分析软件,我们可以创建个性化的视频摘要,该摘要仅由学生的注意力低于某个阈值的部分组成。我们还可以在视频摘要生成中考虑其他条件,例如学生在课堂上没有关注的部分,以及其他学生广泛回放的视频部分,而给定学生则没有。基于注意力和使用情况的实时课程视频摘要是个性化内容的一种形式,建议将它们作为教学视频片段,以突出显示实时会话的重要部分,这对主题理解和考试准备都非常有用。该系统还允许教授查看班上参加现场会议并记录他们的注意力水平的人的总注意力水平。这样一来,她就可以查看学生在活动中哪些部分最关注,也最不关注。我们的大学已部署并使用“帮助我监视”系统,该系统以保护学生的个人数据的方式,以符合GDPR的方式运行。该系统还允许教授查看班上参加现场会议并记录他们的注意力水平的人的总注意力水平。这样一来,她就可以查看学生在活动中哪些部分最关注,也最不关注。我们的大学已部署并使用“帮助我监视”系统,该系统以保护学生的个人数据的方式,以符合GDPR的方式运行。该系统还允许教授查看班上参加现场会议并记录他们的注意力水平的人的总注意力水平。这样一来,她就可以查看学生在活动中哪些部分最关注,也最不关注。我们的大学已部署并使用“帮助我监视”系统,该系统以保护学生的个人数据的方式,以符合GDPR的方式运行。
