ViewMark: An interactive videoconferencing system for mobile devices

ViewMark, a server-client based interactive mobile videoconferencing system is proposed in this paper to enhance the remote meeting experience for mobile users. Compared with the state-of-the-art mobile videoconferencing technology, ViewMark is novel in allowing a mobile user to interactively change the viewpoint of the remote video, create viewmarks, and hear with spatial audio. In addition, ViewMark also streams the screen of the presentation slides to mobile devices. In this paper, we introduce the system design of ViewMark in details, compare the devices that can be used to implement interactive videoconferencing, and demonstrate the prototype system we have built on Windows Mobile platform.
