Using location lifelogs to make meaning of food and physical activity behaviors

In this paper, we take the position that location and information derived from location adds value to health and wellness logs. Traditional health and wellness logs such as food and physical activity diaries do not include location information in a meaningful way. As the ability to track and make sense of location is improving, it will be possible to associate high-quality data regarding the user location and location-derived activities to health and wellness logs. This can significantly improve the ability of these logs to expose meaning to the user, specifically around food and physical activity behaviors. We address four dimensions of location related information: location in terms of places and travels; information derived from location such as roles and transitions; routines identified from places and place transitions; and finally, identifying cohorts and aggregating over routines.
