Increasing Quality of Life Awareness with Life-Logging.

Life Meter is a health mobile application that helps users raise awareness of their quality of life by showing indicators derived from life-logs collected by commercial wearable trackers, smartphone sensors, and manual input. We describe the general infrastructure we developed for the collection and fusion of life-logs, how the quality of life indicators are calculated, and the GUI of Life Meter. The results of a live-user study show that our application has high functionality and subjective quality, and, according to the users, it increases their awareness of the importance of monitoring quality of life.
