Abstract

The purpose of this study is to develop a framework of quantitative evaluation of PUI risk level to ensure the usability in designing mobile devices. Three PUI factors—key type, use scene and device form—were selected as the main criteria for PUI risk level. They are defined as Key Manipulation Value (KMV), Function Manipulation Value (FMV) and Handling Value (HV), considering the requirements. In short, this study provides a framework of quantitative evaluation with the requirements of the three PUI factors, and analyzes risk level by KMV, FMV and HV. This result can be utilized as a criterion for usability at the design phase. In addition, evaluation with this framework at the early design phase helps to anticipate the problems, so the opportunity to solve the problem can be offered in advance.
