Automated capture, integration, and visualization of multiple media streams

The authors discuss their efforts in building a system for the automatic generation, integration, and visualization of media streams-independent information sources that define rich interactive experiences. This research is done in the context of a project called Classroom 2000, an experiment in ubiquitous computing for education. They view teaching and learning as a form of multimedia authoring and have developed a system that generates much of the educational content that occurs naturally in university lectures. They have developed a taxonomy for characterizing different media streams that can be captured during or after a live session and present solutions to two research issues that affect the access of a rich multimedia record. The first issue deals with the granularity of stream integration. The second issue deals with methods of visualizing a set of integrated media streams that is scalable and that supports a user's desire to search by browsing.
