Introducing a New Usability Framework for Analyzing Usability in a Multiple-device System

Abstract

This paper fills in the theoretical gap in the existing usability evaluation literature by introducing a new usability framework: the Usability Paradigm for Multiple Device System (UPMDS). The traditional usability framework for single interface evaluation is not sufficient to analyze usability in multiple-device system, in which the interrelationship between the devices has an impact on user performance. Therefore, the transfer of learning paradigm was adopted. The UPMDS framework consists of two usability attributes: transferability and user perception, which were further decomposed into effectiveness, efficiency, and satisfaction, attractiveness. Three measurement types, behavioral cues, subjective ratings, and self reported results, were suggested to address the existing challenges in usability evaluation. Future research is suggested to utilize the concept of transfer of learning in the area of usability evaluation, and provide empirical validation to the current usability framework.
