Description
The major challenges preventing the wide-scale generation of web lecture recordings
include the compactness and price of the required hardware, the speed of the
compression and posting operations, and the need for a human camera operator. We will
report on efforts that have led to major progress in addressing each of these issues.
We will describe the design, prototyping and pilot deployment of an affordable web
lecture capture device that is portable and robust and which accepts input from a
speaker’s laptop without interfering with its projection onto a screen, and rapidly
archives and posts the synchronized video, audio and slides onto the web. The system
incorporates an infrared camera to provide automatic tracking of the speaker and
thereby removes the need for a camera-operator. We will report on our laboratory
tests of an array of available tracking technologies, the efficacies of each, and the
performance of our current system. We will also report on the development of an
automatic metadata extraction system so that date, time, keywords and other
information can be harvested from each presentation and associated with the recorded
lecture, and entered into a database that is optimally configured for global sharing.
In addition, we will discuss a proposed global standard for an entity called the
"Lecture Object" that would permit recorded lectures to be accessed and replayed by
essentially any user for decades to come, independent of changes in commercial
playback applications. Work on this project was supported with a grant from the U.S.
National Science Foundation.
