An Abstract Framework for Globalising Interactive Systems

We present an abstract framework for designing and developing globalised interactive systems from simple components viewed as games [1] (K. Stathis, M.J. Sergot, Games as a Metaphor for Interactive Systems, in: M.A. Sasse, R.J. Cunningham, R.L. Winder (Eds.), People and Computers XI (Proceedings of HCI’96), August 1996, London, UK, BCS Conference Series, Springer-Varlag, pp. 19–33). We identify a set of concepts required to specify and implement interactions, in such a way whereby instantiating the specifications and implementations of games we obtain components that correspond to localised instances of an interactive system. Localisation is also obtained by either customising the specification or the implementation of the interactive system, or both. The framework also caters for complex interactive systems which are interpreted as compound games built-up from sub-games. In this case, coordination of sub-games is the main issue that we must address at the global level. This is resolved by specifying and implementing sub-games as active components of the more complex games, and, as a result, we localise the coordination of components in the interactive system. The framework lends itself towards a methodology that is suitable for globalising the development of interactive systems. q 1998 Elsevier Science B.V.
