Development of questionnaire to measure user acceptance towards user interface design

Abstract

This study develops a questionnaire that can be used to measure user acceptance of web user interface (UI), particularly web object locations. It explored ASEAN users’ expectations based on constructs in Expectation-Confirmation Theory (ECT). There were eight constructs, namely Expectation (E), Perceived Usefulness (PU), Perceived Ease of Use (PEU), Perceived Performance (PP), Confirmation (C), Satisfaction (S), Continuance Intention (CI), and Interface Quality (IQ). A total of 160 respondents from the ASEAN community were surveyed for their acceptance of web-based prototype. The results provide an exploratory factor analysis of the model, demonstrate satisfactory reliable and valid scales of the model constructs, and suggest further analysis to confirm the model as a valuable tool to evaluate the user acceptance towards informational website. Hopefully, the results of the study will fulfill the need for developing a sustainable web design, particularly in user-centric website which is based on user expectation for web object locations.
