Task- and process-related design of video annotation systems

Various research projects already followed up the design of video annotation applications. Nevertheless, collaborative application scenarios as well as the need of users regarding the annotation workflow have been taken little into account. This paper discusses requirements for the design of video annotation systems. As our main contribution, we consider aspects that can be associated with collaborative use scenarios as well as requirements respecting the support of the annotation workflow not only considering the tasks but also the processes and sequences within. Our goals are to provide the reader with an understanding of the specific characteristics and requirements of video annotation, to establish a framework for evaluation, and to guide the design of video annotation tools
