Software Architecture for Location-Based Games Designed for Social Interaction in Public Space

Location-based games (LBGs) are becoming increasingly more popular, especially those that focus on social interaction in public space. They have been successful to various extents at bringing players together to interact in public space; yet there is lack of knowledge and consensus on how to design these games from a technical perspective. This paper proposes a software architecture that stems from a cross-game analysis of representative games of this genre, in which 6 core architectural components are identified: Augmentation, Navigation, Interaction, State Progression, Participation, and Administration. These components support the game experience of players by enabling orientation and navigation of the players’ own physical environment, their interaction with the game and other people, the traditional game-like experience, management of the entire game ecosystem, and the ability to allow players to fuel game play. An LBG prototype, Secrets of the South, is presented as proof of concept for this software architecture and its key components. This prototype shows that the identified components are pivotal to the gameplay of LBGs for natural interactions in public space and shows how practitioners can be guided in their preparation whilst maintaining their freedom to technically implement this architecture according to the given structure
