The system we propose is a "personal experience capture system", which unobtrusively follows us wherever we go and knows everything that we do. Making use of computing devices ubiquitously embedded in our environment, this Shadow will be able to create a precise record of all of our actions and experiences, including audio, video, location, and time data, as well as other formats, such as logs of all of our correspondence and documents we have edited. High level semantic information such as where we have visited, who we have met, what was said by whom when, what steps were performed in accomplishing a task, will also be captured.
