Conference paper


Collaborative Video Annotation is a broad field of research and is widely used in productive environments. While it is easy to follow changes in small systems with few users, keeping in touch with all changes in large environments can easily get overwhelming. The easiest way and a first approach to prevent the users from getting lost is to show them all changes in an appropriate way. This list of changes can also become very large when many contributors add new information to shared data resources. To prevent users from getting lost while having a list of changes, this paper introduces a way to subscribe to parts of the system and only to have the relevant changes shown. To achieve this goal, the framework provides an approach to check the relevance of changes, which is not trivial in three dimensional spaces, and to be accumulated for later reference by the subscribing user. The benefit for users is to need fewer time to be up-to-date and to have more time for applying own changes.
