Evaluating the user experience of cross-platform interactive systems has become a research issue of increasing importance. There is a lack of clear concepts and definitions for testing, evaluating or even teaching cross-platform user experience. In this paper, we review the actual meanings and interpretations of different concepts in the field of Human-Computer Interaction (HCI) relevant to cross-platform service usage. We also investigate the traditional definitions of usability and user experience before extending them to develop precise definitions for cross-platform usability and user experience. Our paper builds on existing theories to establish the theoretical foundations that can help us better conceptualise cross-platform user experience evaluation.
