User experience evaluation by ERM: Experience recollection method

Abstract

Evaluation of user experience (UX) is the key for improving the quality of artifact that people use in their everyday life and thus improve their quality of life. Two types of evaluation methods can be classified, i.e. the real-time method (e.g. ESM by Larson & Csikszentmihalyi) and memory-based method (e.g. UX curve by Kujala et al.). The ERM proposed here belongs to the latter and asks users to remind their past experience from the time when they had the expectation for targeted artifact and to rate the degree of satisfaction by −10 to +10 rating scale. Two ways of analysis are proposed, one is classifying the result by the aspect of experience and another is classifying the result on the time phase. Web-based application was developed so that the data collection will become efficient.
