探讨影响虚拟现实博物馆系统的视觉不舒适度因素及减缓方法
|
摘要
数字博物馆是实体博物馆在数字空间中的表现形式,虚拟现实技术因其可以产生身临其境的虚拟立体感而在数字博物馆中受到高度重视,但长时间暴露于虚拟现实环境中会产生强烈的不舒适感。针对这一问题进行探讨,介绍在浏览数字博物馆时由视觉引起的不舒适感的主要症状,阐述这些症状产生的原理,通过实验探究影响体验数字博物馆的不舒适感的因素,并提出了动态模糊改变用户视场来减少引起视觉感知冲突的渲染系统,实验表明,此系统可以大幅减缓由视觉因素引起的不舒适感。
Digital museum is a form of physical museum in the digital space. Virtual reality technology has attracted great attention in field of digital museum because it can generate immersive virtual sense of reality. But if people exposure to the virtual reality environment long time,he will have a strong sense of discomfort. To investigate this problem,we introduce main symptoms of visual discomfort caused by browsing virtual object,expound the principle of these symptoms and propose a system which can significantly reduce visual discomfort with HMDs by adjusting dynamic blur field.
