Critical success factors for context-aware mobile communication systems

Numerous context-aware mobile communication systems have emerged for individuals and groups, calling for the identification of critical success factors related to the design of such systems at different levels. The effective system design cannot be achieved without the understanding of situated user behaviour in using context-aware systems. Drawing on Activity Theory, this article advances cross-level, but coherent conceptualisations of context-awareness as enabled by emerging systems. Grounded in the activities of using context-aware systems, these conceptualisations provide implications for system design at individual and group levels in terms of critical success factors, including contextualisation, interactivity and personalisation.
