Life in a Terabyte

According to Lifelog | Metafilter:

LifeLog is interested in three major data categories: physical data, transactional data, and context or media data. “Anywhere/anytime” capture of physical data might be provided by hardware worn by the LifeLog user. Visual, aural, and possibly even haptic sensors capture what the user sees, hears, and feels. GPS, digital compass, and inertial sensors capture the user’s orientation and movements. Biomedical sensors capture the user’s physical state. LifeLog also captures the user’s computer-based interactions and transactions throughout the day from email, calendar, instant messaging, web-based transactions, as well as other common computer applications, and stores the data (or, in some cases, pointers to the data) in appropriate formats. Voice transactions can be captured through recording of telephone calls and voice mail, with the called and calling numbers as metadata. FAX and hardcopy written material (such as postal mail) can be scanned. Finally, LifeLog also captures (or at least captures pointers to) the tremendous amounts of context data the user is exposed to every day from diverse media sources, including broadcast television and radio, hardcopy newspapers, magazines, books and other documents, and softcopy electronic books, web sites, and database access.
