In this chapter, we chart parallel lines of research on mobile technology and daily mobility. Specifically, we review how people engage with mobile technologies in-place and on-the-go, as well as their broader connection with their mobile devices. In each section, we review and link perspectives from psychology and mobility studies towards an integrative understanding of mobile media use. We then survey emerging mobile methodologies with potential for interdisciplinary work. To conclude, we collapse these boundaries – between being in-place and on-the-go, and mobile technology and daily mobility – to consider the trajectory of future research on the psychology of mobile technology.
