Abstract. With the emergence of pervasive technology, pervasive games came into existence. Most are location-aware applications, played with a PDA or mobile phone. We argue that the interaction paradigm these games support, limits outdoor play that often involves spontaneous social interaction. This paper introduces a new genre of pervasive games we call Head Up Games. The paper describes these games and how they differ from current research prototypes of pervasive games. Also, it outlines their characteristics and illustrates our vision with Camelot, an outdoor game for children.
