A methodology for assessing user´s skill grade to implement adaptive user interface systems

A methodology, for assessing a user´s skill grade is a key technology for developing adaptive user interfaces. The methodology presented assesses a user´s skill grade by analyzing the tendencies of the user´s operations. In order to analyze these tendencies, we categorized user´s operations into three categories and extracted data from the logs on which the user´s operation behavior was recorded. We discuss the methodology for assessing a user´s skill grade and the system architecture, and then we describe the results of a preliminary experiment and a new experiment with the prototype based on the new architecture.
