The Influence of Motion Factors on Perception of Motion in VR Spaces.

Providers sometimes create moving arrows, 3D objects, effects, and other items to guide the users of VR spaces. It should be possible to provide better visual guidance and increase its effectiveness by investigating how users feel about how these guiding items move in VR spaces. In this study, with the aim of creating more effective interactions for visual guidance, we provided subjects with the task of visually registering the trajectory of a moving body in a VR space using simple solid shapes. We investigated how the user’s perception of motion was affected by the speed of movement and range of movement of the object and by the distance between the user and the object. We found that the optimal distance for perception of motion in a VR space was 12 meters, and the wider the range of movement, the higher the correct answer rate. It was found that the object’s speed of movement had a small effect on the perception of motion if the speed was within the range in which its motion could be registered. It was also revealed that the combination of the distance between the user and the moving body and the speed at which it moves significantly affects the user’s perception of its motion. A subjective evaluation showed that users felt that ‘speed’ greatly affects their perception of motion. [ABSTRACT FROM AUTHOR]
