A Modular Approach to the Evaluation of User Experience: The meCUE Questionnaire Michael Minge, Laura Riedel, Manfred Thüring User Experience includes “all aspects of a person’s perceptions and responses that result from the use or anticipated use of a product, system, or service” (ISO 9241 part 210, 2010). As most important aspects of human-technology interaction, the CUEModel by Thüring and Mahlke (2007) specifies the perception of instrumental and non-instrumental product qualities as well as emotional user responses. The impact of these three components on users’ overall appraisal and future usage could be demonstrated empirically (Thüring & Mahlke, 2007; Stein, Minge & Thüring, 2011). Based on the CUE-Model, a new measurement tool was developed, the meCUE questionnaire. meCUE consists of three modules providing a comprehensive evaluation of User Experience. The first module contains a subset of scales measuring instrumental (effectiveness, efficiency) and non-instrumental (visual aesthetics, status, commitment) perceptions of interactive products. The second module addresses positive and negative emotions. Finally, the third module measures consequences of usage (product loyalty, intention to use). In sum, meCUE contains 33 seven-point Likert scaled items. An empirical study under laboratory conditions aimed to determine reliability and validity of meCUE. Sixty-seven participants worked on three different products respectively (digital audio player, mobile phone, and software). Each product was evaluated by the use of meCUE and a number of widely accepted questionnaires (e.g. AttrakDiff, UEQ, SAM, PANAS). Principle component analyses were performed for each module of meCUE. Results confirm the anticipated structure of factors and show a large percentage of explained variance (72 % up to 81%). Reliability indices (Cronbach’s Alpha) ranged between .76 and .94. The assumption of validity was supported by substantial correlations between meCUE and other questionnaires (construct validity) and by significant differences between ratings of various products (discriminative validity).
