A comparative usability evaluation was performed using various subjective evaluation methods, including Mobile Phone Usability Questionnaire (MPUQ). Further, decision-making models using Analytic Hierarchy Process (AHP) and multiple linear regression were developed and applied. Although the mean rankings of the four phones were not significantly different across the evaluation methods, there were variations across the methods in terms of the number of rank orderings, preference proportions, and methods to select their initial preference. Thus, this study provided a useful insight into how users make different decisions through different evaluation methods. Also, the result showed that answering a usability questionnaire affected a user's decision-making process for comparative evaluation.
