Direct camera control for capturing meetings into multimedia documents

Currently, only experts can manage to capture activities in a conference room using multiple cameras because of the complexity of the task. We conducted interviews with experienced operators as well as video analysis on their outputs. Typical design of user interface for camera control was found out to be demanding users a lot of internal computations. A new interface for direct camera control is introduced to overcome the problem and tested in a real environment. The results well supported our usage model and proved our interface is effective.
