A programming system for the dynamic manipulation of temporally sensitive data

In computer-participative multimedia applications, the computer not only manipulates media, but also digests it and performs independent actions based on media content. In this report I discuss an approach to the design of environments to support the development of computer-participative multimedia applications and I describe the implementation of the VuSystem, a computer-participative multimedia system built using this approach. The system is unique in that it combines the programming techniques of visualization systems and the temporal sensitivity of multimedia systems. I report measurements made of the performance of the VuSystem, which demonstrate its practicality. I conclude with a brief summary of users' experiences with the VuSystem, and suggests future directions for research in this area. c Massachusetts Institute of Technology 1994 This research was supported by the Advanced Research Projects Agency of the Department of Defense, monitored by the United States Air Force (AFSC, Rome Laboratory) under contract No. F30602-92-C-0019, and by grants from Nynex and Digital Equipment Corporation.
