Abstract (in Japanese) (See Japanese page) 
(in English) On the button-input interfaces used in information devices, such as controllers, automatic teller machines (ATM) and ticket machines, we have conducted the experiment using virtual button interface to evaluate the physical workload, or usability. In our experiment, it was formulated a U-shaped curve against increasing the number of buttons, and, as such, must have a unique optimal number of buttons in the sense of reducing the physical workload. Furthermore, we globally analyzed that it was evaluated by two sorts of sub-workload, search and operational workloads on the button input. In this report, we investigated statistical distributions obtained by local behaviors on the button input. To this end, we measured gaze points during the button-input operation. We showed that the motion of gaze points was able to be modeled by the Levy flight.
