Flikken: Programming a Mobile Game with Context-Aware Tuples

This document describes the implementation of Flikken, a mobile game implemented using context-aware tuples in which players equipped with mobile devices interact in a physical environment augmented with virtual objects. Coordination and interaction between players is fully specified by means of context-aware tuples and reactions to some of these tuples e.g. to show on the GUI the virtual objects spread around the city. We describe the game functionality and the contexttuples used in its implementation. Before concluding, we provide code snippets for the relevant parts of the game implementation. This document assumes the reader understands the Context-Aware Tuples model and knows the operations it provides.
