Outline of Final Research Achievements

This study investigated if observers' manual control of the stimulus change removes ambiguity of KDE. In the experiment, the stimulus change could be controlled by the rotation of a computer trackball that the observer manually rotates rightward or leftward. As the result, manual control could remove the ambiguity in a part of our subjects: the perceived direction of rotation from KDE united the manual control. Prolonged viewing, however, made reverse the perceived direction of rotation. We measured duration from the beginning of stimulus change (i.e. rotation) until reverse. The mean duration in the case of manual control is almost equal to that of conventional KDE. Manual control had no effect in the rest of our subject. They always perceived unidirectional rotation from conventional KDE.
