MUX: Development of a Holistic Mobile User Experience Instrument

Abstract

User experience practitioners have benefitted from the availability of usability measures that are short, generalizable, and easy to interpret, such as the System Usability Scale. However, such generalizable instruments fail to address many of the key characteristics of software applications that can be used across a range of mobile devices. Our response is development of MUX, a mobile user experience instrument that provides holistic assessment of specific software-device use scenarios. We find that MUX self-report scales assessing Nuisance, Mobility, and Access can be applied to effectively augment measures of the System Usability Scale or can be used as a standalone instrument for rating and comparing user experiences in mobile computing.
