Abstract
The Authors have proposed a method that detects inconsistencies between user interaction logs of a task and desired sequences for the task based on mouse click coordinate logs. The method models two successive clicks as a vector and thus a sequence of operation in a user/desired log as a sequence of vectors. To detect inconsistencies in user interactions and desired sequences, each vector from user logs is compared with each vector from desired logs. The Authors have developed a computer tool for logging and analyzing user interactions and
desired sequences by the proposed method. The tool has applied to evaluation of "Sophia," a web-based system for browsing and searching assembly minutes. A total of 23 problems was found in three vers. of the system.
