The concept of lifelogging goes right back to the 1970s, when Steve Mann, a professor of electrical engineering at the University of Toronto in Canada, started capturing video using a camera mounted on a helmet. By the mid 1990s he was broadcasting his every move, and even his heartbeat, online. However the word lifelogging itself was not coined until the late 1990s by Gordon Bell, an American computer engineer and the subject of Microsoft’s research project MyLifeBits, a 10-year experiment in which Bell recorded his daily life by wearing a special neck camera referred to as a SenseCam.
