Social Editing of Video Recordings of Lectures
Margareta Esponda, Benjamin Jankovic – 2008
In this paper we show how video recordings of lectures can be enhanced through “social editing”, a special sort of “human computation”. We record lectures using six cameras arranged to produce a panoramic view (360 degrees) of the classroom. After recording, viewers can replay the lectures on a computer and can navigate through them tilting and zooming a virtual camera. All user interactions are recorded by the system, and are later used to decide which views should be stored and their zoom level. The result is an automatically edited video as a result of the social navigation of the first few initial viewers of the lecture.
