Abstract:

Crossing event in VR movies has strong visual impact on observers and can provide an ideal environment for immersion. To explore the methods of layout and kinematic design in VR movies, task-based perception experiment has been designed to analyze the relationship between response time and start position, velocity, and depth of endpoint. At the same time, the effect of movement on immersion, comfort and emotion can be analyzed through subjective questionnaire, and sense perception regularity of crossing events can be built. The experiment results indicate that standard deviation of response time significantly increases with depth, that the object crossing left has lower loss rate and is more enjoyable, and that the objects crossing right above or below are most annoying and have the lowest and highest loss rate respectively. It is also learned that the one below breaks immersion seriously, and that slow object ($\leq 20$ m/s) gets noticed quickly when it stops at the middle of space behind people, while fast object ($\geq20$ m/s) has higher loss rate when it stops at the same place.
