How Much Is Too Much? Using Magnitude Estimation For User Experience Research

Abstract

This paper discusses the use of magnitude estimation, a
method with roots in psychophysics, as a tool for evaluating user
experience. Using two healthcare-related case studies for illustration,
we describe the advantages and disadvantages of applying this method,
relative to more traditional ranking and rating scales. We also discuss
lessons learned and provide recommendations for researchers considering
the use of magnitude estimation to evaluate user experience.
