A Lens Model Approach for the Relationships Between Pre-Use Perceptions and Post-Use Responses
Kwang-Kyu Seo, Sangwon Lee · Journal of Computational and Theoretical Nanoscience · 2013
This study introduces the lens model approach to find a possibility of checking the relativity of computer-based applications in terms of users' responses and applies it to a real case with online bookstores. The case study was conducted in two Viewpoints: the relationship between expected usability and user performance and the relationship between pre-use preference and post-use preference. The first is to examine how much users' perceptions of usability before actual use match performance measures in a real usability testing, and the second is to determine how strongly pre-use preferences and post-use preferences were connected. Through the lens model approach to this case study, we could discuss the possibility of predicting users' post-use responses for the online bookstore web sites without a direct usability testing. This approach can be utilized as bases for developing a simple heuristic method to quickly evaluate users' responses in a limited time and can be applied to various user interface and user experience issues such as decision-making in human-computer interactive systems.
