Lifelogging
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.[1] 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.[2]
Examples
[edit | edit source]Template:Original research section A known lifelogger was Robert Shields, who manually recorded 25 years of his life from 1972 to 1997, at 5-minute intervals. This record resulted in a 37-million word diary, thought to be the longest ever written.[3]
Steve Mann was the first person to capture continuous physiological data along with a live first-person video from a wearable camera.[4] Starting in 1994, Mann continuously transmitted his life — 24 hours a day, 7 days a week.[5] Using a wearable camera and wearable display, he invited others to see what he was looking at, as well as to send him live feeds or messages in real-time.[6] In 1998 Mann started a community of lifeloggers (also known as lifebloggers or lifegloggers) which has grown to more than 20,000 members. Throughout the 1990s Mann presented this work to the U.S. Army, with two visits to US Natick Army Research Labs.[7]
In 1996, Jennifer Ringley started JenniCam, broadcasting photographs from a webcam in her college bedroom every fifteen seconds; the site was turned off in 2003.[8]
"We Live In Public" was a 24/7 Internet conceptual art experiment created by Josh Harris in December 1999. With a format similar to TV's Big Brother, Harris placed tapped telephones, microphones and 32 robotic cameras in the home he shared with his girlfriend, Tanya Corrin. Viewers talked to Harris and Corrin in the site's chatroom.[9] Harris recently launched the online live video platform, Operator 11.[10]
In 2001, Kiyoharu Aizawa discussed the problem of how to handle a huge amount of videos continuously captured in one's life and presented an automatic summarization.[11]
The lifelog DotComGuy ran throughout 2000, when Mitch Maddox lived the entire year without leaving his house.[12] After Joi Ito's discussion of Moblogging, which involves web publishing from a mobile device,[13] came Gordon Bell's MyLifeBits (2004), an experiment in digital storage of a person's lifetime, including full-text search, text/audio annotations, and hyperlinks.Template:Citation needed
In 2003, a project called LifeLog was started at the Defense Advanced Research Projects Agency (DARPA), under the supervision of Douglas Gage. This project would combine several technologies to record life activities, in order to create a life diary. Shortly after, the notion of lifelogging was identified as a technology and cultural practice that could be exploited by governments, businesses or militaries through surveillance.[14] The DARPA lifelogging project was cancelled by 2004, but this project helped to popularize the idea, and the usage of the term lifelogging in everyday discourse. It contributed to the growing acceptance of using technology for augmented memory.[15]
