Abstract
In order to expand the scope of the concept of UX (User Experience), authors conducted a research on the descriptive words of various types of experience by introducing a concept of GOB (Goal Oriented Behavior), POB (Process Oriented Behavior) and SOB (State Oriented Behavior) to cover the various ranges of human behavior. From the perspective of usability engineering, achieving the goal (GOB) is the fundamental presupposition in terms of the behavior of the user hence the satisfaction can be regarded as an important measure. In other words, people will be satisfied by achieving the goal in the situation where the usability matters. But the concept of UX is wider than the usability and it was assumed that different words should be used for representing the nature of different types of behavior. A set of descriptive words including the satisfaction was tested for different types of behavior and it was found that different types of experience should be described differently in terms of their pragmatic and hedonic (Kansei) aspects.
