AHP를 통한 모바일 GUI의 사용성 평가 항목 분석

Abstract

Background In order to systematically evaluate various mobile applications in the rapidly changing smartphone market, usability evaluation criteria suitable for the characteristics of the latest devices must be prepared. Accordingly, this study aimed to develop a usability evaluation factors suitable for the characteristics of the latest mobile service. Methods In the preliminary investigation stage, a literature study on usability was conducted, and items with a high proportion in common were selected first. At this time, usability principles were largely divided into principles for product/software evaluation and principles for mobile evaluation. In this study, the priorities among factors were investigated and derived using the AHP hierarchical decision-making method. Result The items selected in the preliminary survey were efficiency and aesthetics. In this study, as a result of the AHP survey, consistency was evaluated as the most important factor, followed by understandability, controllability, intuitiveness, flexibility, visibility, readability, error prevention, conciseness, and standardity. Intuition was evaluated as the most important factor in product/software, consistency was evaluated as the most important factor in mobile, and consistency was evaluated as the most important factor in overall. Conclusion Items derived from the preliminary survey and items derived from the AHP analysis in the main survey were integrated to select items suitable for mobile GUI. It is proposed to designate the final usability evaluation factors selected through this analysis method as intuitiveness, visibility, consistency, understandability, controllability, efficiency, and aesthetics.
