 note = {In this paper, we measure electroencephalograms (EEGs) for quantitative evaluation of software usability. Two different (newer and loder) versions of same software were selected to intentionally defferentiate a subjects' mental state in our experiment. The versions have graphical user interfaces (GUIs) for the main window, which is extremely different from each other, such as different name of menus, commands and different appearance of command dialogs. While the older version is easy to use for our subjects, the newer version of the software is more likely to disturb users' tasks because it requires a user to restudy the interface of the software, Therefore, we can easily compare subjects' EEGs in an uncomfortable situation with that in a comfortable situation. In the experiment, we used alpha-wave, beta-wave, and beta/alpha as metrics of subjects' EEGs. As the result, we found significant differences of alpha-wave, beta-wave and beta/alpha between two versions. The results of questionnaires performed after the experiment supports the differences, and we also found the correlation between the metrics and result of the questionnaire.},
