In this study, we verified the occurrence of visually induced self-motion during a motion movie that included both unpredictable and predictable components by measuring body sway. Eleven subjects watched a static movie for 1 min and 8 sinusoidally moving movies (direction setting: 2, added unpredictable component settings: 4) for 180 s each. The results revealed the following: First, a viewing depth-direction predictable motion movie had high phase synchronization acuity. In contrast, the unpredictable motion component considerably affected the viewing side-direction motion movie. Second, the relationship between the amount of added unpredictable motion components and the synchronization acuity was poor.
