Modeling of a human decision-making process with prospect theory

Abstract

The aim of the present study is to examine what rationality conditions are ignored and why it happens when users have more than one dimension in conflict, such as perceived security and usability in the online banking use experience. In a controlled experiment, thirty subjects used two different online banking authentication interfaces: a fingerprint interface and a normal four-step interface, in a reverse order. The empirical findings revealed that a different combination of rationality conditions was employed based on a change from effortless interaction (e.g., the fingerprint) to effortful interaction (e.g., the four-step logon system) or vice versa. We also provided some design implications for HCI practitioners, and proposed a new approach to evaluate user experiences as there are benefits and drawbacks mixed in user interface design.
