We try to both inform about the developments and influential works in the fi eld of Pervasive Games, and also help laying the foundation for shaping the future of this application domain. Consequently, we focus on concepts and theoretical works that help understanding and sharpening the rationale behind the field (the "what") as well as on technological means of actually realizing working prototypes of Pervasive Games (the "how"). Both perspectives have their right and need to go hand in hand. The first four of the twelve chapters contributed by leading experts in the fi eld address the theoretical foundations. The individual authors' views sometimes complement each other, sometimes they express similar ideas and concepts, and sometimes they even contradict each other severely. Since we are currently far from having established a common ground about what this emerging genre clearly defi nes and separates from related fields, we suggest treating the individual chapters with equal respect and being prepared to contribute to the fi eld with one's own thoughts and ideas that might help further shape and clarify the important issues of Pervasive Games.}}, author = {{Magerkurth, Carsten and Röcker, Carsten}}, booktitle = {{A reader for pervasive gaming research ; Vol. 1., Concepts and technologies for pervasive games }}, isbn = {{978-3-8322-6223-5}}, keywords = {{Pervasive Gaming Applications, User Interfaces, Smart Home Environments, Mixed Reality}}, publisher = {{Shaker}}, title = {{{Towards the Emergence of a New Application Domain}}}, volume = {{5-9}}, year = {{2007}}, } @inbook{4771, abstract = {{Pervasive Games have become popular in recent years.
