Abstract

Abstract:

A virtual reality (VR) image viewpoint over-axis evaluation experiment was designed to explore the application feasibility of ordinary film montage design elements in VR movies. By analysing the objective data of eye tracking and spatial markers as well as the subjective data of visual continuity perception, spatial perception, immersion, and comfort, the influence of a VR image over-axis lens assembly on the audience is studied; the feasible axis rules are also summarized. The experimental results show that the VR image is not limited by the axis rule of traditional film. VR images have a unique set of rules. As such, when viewing VR images of different angles and different speeds, the objective spatial marker deviation, visual tracking degree, and subjective score can be maintained within the acceptable limits. This demonstrates that it is possible to cross the traditional axis to shoot in VR formats. No discomfort is caused to any users that took part in this research.

Key words: axis rules, virtual reality, montage assembly
