The work in this book was conducted at an exciting point in time when the whole field of Human-Computer Interaction shifted its focus away from settings in which people would sit more or less still in front of static computers, to instead start exploring how to make good use of all the added possibilities of technologies that can be moved around. At the same time, researchers became increasingly interested in aspects of experience and enjoyment in the use of technology. As discussed in the introduction, notions such and play and learning, work and leisure, casual and serious technology use, are sometimes presented as conceptual dichotomies that may be difficult to combine. However, to many people, such distinctions are not meaningful, since practices and technologies – especially mobile ones – travel between the different social spheres of our lives, accompanying them wherever they go. Therefore,

addressing aspects of leisure, pleasure and play is a relevant challenge for most interaction designers. In many cases, mobility and enjoyment seems very tightly intertwined, and in this chapter I will discuss different ways that this has become manifested in the illustrated pages of this book.
