Response to commentaries on 'The Usability Metric for User Experience'

摘要

The Usability Metric for User Experience (UMUX) is a four-item Likert scale aimed at replicating the psychometric properties of the System Usability Scale (SUS) in a more compact form. As part of a special issue of the journal Interacting with Computers, the UMUX is being examined in terms of purpose, reliability, validity and structure. This response to commentaries addresses concerns with these issues through updated archival research, deeper analysis on the original data and some updated results with an average-scoring system. The new results show the UMUX performs as expected for a wide range of systems and consists of one underlying usability factor.
