Cross-platform usability and eye-tracking measurement and analysis model

Evaluating the usability of cross-platform interactive systems has become increasingly important. Despite the increasing number of such interactive systems cross platforms and hence the corresponding increase in the need for horizontal usability evaluation, measurement and analysis methods, insignificant work has been done on this new theme of usability. We have developed an initial Eye-Tracking Measurement and Analysis Model for Cross-Platform Usability (CPU-EMA), a usability engineering evaluation and analysis method, to evaluate cross-platform interactive systems. This paper provides eye movement-related metrics, which can be used to measure cross-platform usability. The horizontal usability analysis (refers to cross-platform usability analysis) associated with the developed eye movements metrics has been discussed, in order to support user experience evaluators, and multi-interactive systems designers in interpreting the eye movement data cross multiple interactive systems. Reflections on how CPU-EMA should be used during the cross-platform usability testing sessions are also presented.
