Divided into four sections, each section comprises a set of chapters on a different topic and is introduced by a key author in the field who provides an overview of the content. The book itself is introduced by Paul Dourish, who sets the theme of shared encounters in the context of technological and social change over the last fifteen years. The four sections that follow consider the characteristics of shared encounters and describe how they can be supported in different settings: the first section, introduced by Barry Brown, looks at shared experiences. George Roussos, in the second section, presents playful encounters. Malcolm McCulloch introduces the section on spatial settings and - last but not least - Elizabeth Churchill previews the topic of social glue. The individual chapters that accompany each part offer particular perspectives on the main topic and provide detailed insights from the author's own research background.

A valuable reference for anyone designing ubiquitous media, mobile social software and LBS applications, this volume will also be useful to researchers, students and practitioners in fields ranging from computer science to urban studies.
