Capture the flag: Mixed-reality social gaming with smart phones

The computer game, Capture the Flag (CFT), which uses mobile devices, PCs, and a network to combine real-world and virtual game play, is discussed. The use of smart phones creates a direct, real-time linkage between the real and the virtual worlds. CFT explores novel tangible aspects of human physical movement and perception, both in the real-world playing environment and in interaction with the virtual world. This game heralds the conjugation and growth of a new genre of computer game that is built on mobility, physical actions, and the real world as a playground.
