In this chapter, we discuss wearable imaging in the context of human lifestyle and behavior sensing. We consider imaging as both context information to derive labels for other sensor data and as a measure of daily situations to study people’s lives. We begin with a brief historical perspective and discuss how the capture of everyday situations and activities can be used as an alternative to direct observation in field studies; our focus is on the acquisition of ground-truth labels to train activity recognition systems. Next, we describe the practical challenges associated with wearable cameras, such as placement and positioning, and we contrast these challenges against those of other popular sensing modalities. Several lifelogging application scenarios are presented, including event segmentation, localization, dietary monitoring, action recognition, and social interaction analysis. The chapter concludes with lifelogging privacy considerations, future opportunities, and best practices and recommendations for how to best leverage wearable cameras in research.
