The person who configures and gives the stimuli and observes the result is called a user of this program, while the one who gets the stimuli and whose data are measured, a subject. When the power to the stimulus setting tool bar is turned on, the functions of the stimulus setting tool bar are activated on the user’s monitor, and the stimulus monitoring window through which the user can verify the stimuli given appears. In case the user has a video camera installed, he or she can select the video setting in order to observe the subject getting the stimuli and providing the measurement data. The video setting method is explained in Chapter 3. Software Outline. Besides, on the subject’s monitor, only the stimulus window that presents the stimuli appears. While taking the measurement, the subject accepts the stimuli watching this stimulus window.
