Techopedia explains Lifelog
The applications for lifelogging are diverse. Individuals who display their private lives through continual webcam surveillance could be classified as lifeloggers. Others may wear cameras that record certain kinds of locational data and other information to log their lives in real time. The prolific use of social media could even be called lifelogging, since many of these tools serve to update the user’s location, purchases, activities and even feelings in real time. A good example of of lifelogging is the very popular JenniCam site operated by Jennifer Ringley throughout parts of the 1990s that documented the woman's life and displayed it on the Internet. Today, the use of Facebook, Twitter, Foursquare and other social media applications probably constitutes the majority of this type of activity, although there are more dedicated lifeloggers using more specific technologies to map their activities in real time more thoroughly.
