Preface

Abstract

Interactive digital media forms, such as games, are an important part of our society. Beyond entertainment, interactive and collaborative digital media creates social bonds between people by providing a shared reality for people separated in time and space. Interactive media is increasingly used in education and in ameliorating the cognitive and physical health of the players. Collaborative media interactions can in- centivize crowds of players to solve difficult problems, and researchers now leverage virtual worlds to serve as a research laboratory for understanding human behavior.
