Abstract

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.
