Paper Abstract

Most conferencing systems are focused on facilitating one of two types of meetings: those in a single room, consisting entirely of collocated participants, or those with isolated individuals at different physical locations. Our experiences are of a third style: hybrid meetings consisting of both collocated groups and isolated participants. We illustrate the limitations of using an existing desktop-based tools in the shared meeting room portion of this hybrid meeting style, and propose adding a software control substrate matched to the specifics of the application to address the inadequacies. We derive requirements for the in-room applications, and, as a concrete example from the domain, describe the design and implementation of an application for manipulation of in-room shared video display. Our design employs a user interface split across multiple physical devices paired with a control protocol managing communication between them. The client portion runs on wirelessly-connected portable devices (laptops and 3Com Palm Pilots) and supports per-user input; the server portion handles presentation of shared output on a video monitor. Our design is optimized for meeting room use in three ways: simplified operation to reduce demands on attention, support for remote control, and support for access by multiple simultaneous users.
