A Usability Model to Predict User Experience in E-Commerce

摘要

This pilot study, part of a larger study aimed at building a model using usability factors to predict the e-commerce user experience, looks at the effect of page layout, navigation techniques, security and privacy and perceived usefulness on the userexperience. A large base of research on the usability of computer systems exists. Traditionally this was aimed at optimizing the task performance of expert users (D’Hertfelt, 2000), but the introduction of e-commerce has caused a widening of the focus of HCI to include aspects typically found in marketing and sociology. New fields such as user experience strategy, the design of consumer trust and Captology, the design, theory and analysis of persuasive technologies, are emerging (de Groot, Eikelboom &Egger, 2001), with the actual interaction with the customer becoming of paramount importance.
