Title: DejaView - a Personal Virtual Computer Recorder
Abstract: Continuing advances in hardware technology have enabled the
proliferation of faster, cheaper, and more capable personal computers.
As users interact with the world and their peers through their
computers, it is becoming important to archive and later search the
information that they have *viewed*. Exponential improvements in
processing and storage are not making this problem any easier, and
existing state-of-the-art desktop search tools fail to provide a suitable solution.
DejaView is a personal virtual computer recorder that provides a
complete record of a desktop computing experience. DejaView
continuously records a user's session to provide a complete WYSIWYS
(What You See Is What You've Seen) record and enable a user to
playback, browse, search and revive records. DejaView combines
transparent operating system, display and file system virtualization,
with semantic information recorder and a desktop search system, to
provide this functionality without any changes to applications, window
systems, or operating system kernels. Experimental results show that
DejaView provides continuous recording without any user noticeable performance degradation, and is fast enough for interactive use.
