초록
In this paper, we first point out the limitation of the existing methods in usability evaluation, and propose a new method to find tasks and users that can cause problems in the use of software applications. To deal with object-based applications, we define unit actions and divide a given task into the sequence of unit actions. Then, we propose a new measure to calculate the degree of lostness for the unit actions. In several experiments, we show the proposed method can represent the usability well while the previous method has a problem in object-based applications. We also find that the user’s evaluation is more related to the proposed method than the previous method based on execution time through correlation analysis.
