摘要

LectureSight项目旨在开发一种具有成本效益的解决方案，用于讲座录音的自动摄像机控制。早期的工作展示了该系统的原型实现。在这项工作中，我们展示了在两个实验中测试系统的结果:LectureSight实例部署在两个房间中，并在现场讲座中评估了系统的性能。此外，还进行了一项实验研究，以调查带有演示者跟踪的视频对学习者的有用性。该实验涉及来自两所大学的参与者，他们被置于模拟考试环境中。

The LectureSight System in Production Scenarios and Its Impact on Learning from Video Recorded Lectures

The LectureSight project aims to develop a cost-effective solution for automatic camera control for lecture recordings. An earlier work presented the prototypical implementation of the system. In this work we present the results form testing the system in two experiments: LectureSight instances were deployed in two rooms and the performance of the system was assessed in live lectures. Furthermore an experimental study has been conducted to investigate the usefulness of videos with presenter tracking for the learner. The experiment involved participants from two universities that were put into a simulated exam situation.
