Current business presentations are commonly multimedia-based and with the realization of the mobile enterprise, accessing of such presentations stored on servers from mobile devices becomes increasingly common. However as a roaming mobile device user moves, factors that change include the local wireless network technology, the available bandwidth, the currently closest source of the media files and even the continuity of wireless access. The XML-based standard, synchronized multimedia integration language (SMIL), provides a format to specify the display sequence and layout of media files in a multimedia presentation. We present a SMIL-based system for mobile devices that is able to dynamically adapt presentations in response to such changing mobile computing-related factors as those given above.
