The talk I was most looking forward to seeing Saturday at the Accelerating Change Conference 2004 was the one by Gordon Bell, from Microsoft's Bay Area Research Center, talking about MyLifeBits. MyLifeBits is an early attempt at what I call a "personal memory assistant" -- a device which would stores copies of everything you see and hear, for later retrieval as needed. MyLifeBits isn't quite that powerful; it only stores personal documents, web pages browsed, selected images, audio records of phone calls, and a few other file types. It's really intended as a vehicle to allow engineers to figure out what the barriers would be for the fuller version.
So far, they've learned a few key things: meta-data is really the core of something like MyLifeBits -- the annotations and contextual information that makes a stored file meaningful; of the various kinds of meta-data one could automatically or manually add, date and time is ultimately the most important; once something is stored, the challenge then becomes user interface -- how do you find something that you've stored? These lessons are more common sense than big surprises, but the Microsoft BARC team has taken some important steps towards figuring out some solutions.
Two more items of note: BARC's term for a device to do constant capture of what the user hears and sees is "CARPE" (continuous archival recording of personal experience); and the idea of a system to store copies of everything you've ever read, written or heard was anticipated nearly 60 years ago, in a 1945 article called "As We May Think," by Vannevar Bush. If you haven't read it, you should -- it's a wonderfully prescient vision.
