MyLifeBits is a project to assist one’s memory, including chronicling a person's life by encoding every aspect of one's communications with people and machines, what is heard and seen, and many aspects of their physical existence. What started capturing books and papers evolved to art, articles, books, cards, email, letters, memos, papers, photos, posters, and even coffee mugs and T-shirt logos. A year ago, it was clear that the system is fundamentally a transaction processing database for all personal interactions with the computer and other devices e.g. SenseCam that captures 1-2 thousand photos a day.
