Abstract

Usability has been regarded as a critical factor affecting the quality of mobile phones. Many studies have examined usability impact factors of mobile phones on the basis of software usability concepts. However, considering mobile phones as multi-media and information appliances, a new usability concept and associated factors should be developed. This paper proposes a conceptual framework which has five views to reflect different aspect of interactions between users and mobile phones, and from which various usability impact factor models can be derived. Five views include user view, product view, interaction view, dynamic view, and execution view. Furthermore, we developed a hierarchical model which organizes usability factors in terms of goal-means relations. Through two case studies, we could verify the usefulness of the framework and model. Lastly, we developed a set of checklists that are helpful to measure the usability of mobile phones, thereby increasing the practicality of the framework and model.
