Lifelogging

摘要

In 1945, American engineer Vannevar Bush introduced the idea of a person's memex - "an enlarged intimate supplement to his memory" - that would store, search and retrieve a lifetime's books, records and communications. Fifty years later. Bill Gates wrote that "someday computers will store everything a person has ever seen and heard".rnThat day is now here. Since 2001, Jim Gemmell and I have demonstrated many aspects of complete "lifelogging", storing letters, papers, photos, videos and voice recordings associated with my life in an annotated and searchable database. Terabyte memory storage coupled with digital cameras, biosensors and GPS means we can now log everything about an individual in real time, from their location to aspects of their physical state such as energy expenditure, heart rate and stress levels.
