Lifelog

For the proposed project of the same name, see DARPA LifeLog.
Evolution of lifelogging apparatus, including the wearable computer, camera, and viewfinder with wireless Internet connection. Early apparatus used separate transmitting and receiving antennas. Later apparatus evolved toward the appearance of ordinary eyeglasses in the late 1980s and early 1990s.[1]

A lifelog is a personal record of one's daily life in a varying amount of detail, for a variety of purposes. The record contains a comprehensive dataset of a human's activities. The data could be used to increase knowledge about how people live their lives.[2] In recent years, some lifelog data has been automatically captured by wearable technology or mobile devices. People who keep lifelogs about themselves are known as lifeloggers (or sometimes lifebloggers or lifegloggers).

The sub-field of computer vision that processes and analyses visual data captured by a wearable camera is called "egocentric vision" or egography.[3]
