Development of an UX assessment model based on network analysis

Abstract

This paper introduces a novel approach to assess user experience (UX) by calculating relation of concepts based on network analysis. Since it is highly subjective and context-dependent, there was only marginal success in building quantification models for UX. This paper suggested UX assessment model to quantify the satisfaction level of user experience by assuming user values could be represented with network structure and centrality measures. As a case study, gesture interface for TV was investigated. Three core values were able to be identified, and an UX assessment model was proposed. In addition, the model was validated via quantitative study. The quantitative study collected objective and subjective performance measurements which are related to the peripheries of core values. The result revealed that identified user values significantly affected the overall level of satisfaction, whereas normalized link strengths were not much coincided with the correlation coefficients. This study suggested that an UX assessment model can be used to reveal important user values that affect user's perceived satisfaction.
