In resent years, virutal reality(VR) technology have applied to many fields with rapid advantage of hardware's performance. However, current VR systems using liquid crystal shutter glasses do not achieve accurate depth perception and have problems of difference of perception between humans. Humans use multiple visual cues of 3D and characteristic of visual sense when detecting dimensionality. In this paper, we selected three factors that are rotation of virtual object in visual cues, dominant eyes in human visual characteristic, and size correction of virtual object in display method. The experiment investigated the influence these factors on depth consciousness distance and subjective sense of incongruity As a result, rotation of a virtual object and dominant eyes is almost ineffective to an improvement of depth consciousness distance, futhermore difference between subjects were still large. But in size correction depth consciousness distance and difference between subjects are improved for some subjects.
