The Lifebrowser is a Microsoft Research project that processes your pictures, emails, web history, calendar events and other documents stored in your personal computer and presents them in a timeline interface.

"The motivation behind Lifebrowser is that we have too much stuff going on in our personal digital spheres," says Eric Horvitz, the distinguished scientist at Microsoft who created Lifebrowser. "We were interested in making local machines private data-mining centers [that are] very smart about you and your memory so that you can better navigate through that great amount of content."
Technovelgy readers are familiar with the idea of a lifelog; a device that you can hang around your neck to take pictures at regular intervals of whatever you are seeing. The concept and device were originally developed by DARPA in 2003. DARPA eventually canceled it, in part due to privacy concerns.
Microsoft also created the SenseCam, a device designed to take pictures at a regular interval. (The Momenta PC is a much more attractive concept.)
