虚拟现实中可视化及声音表达的几点思考

Some Concerns with the Visualization and Sound Expression in Virtual Reality

结合虚拟现实的现状,本文重点对可视化及声音在虚拟现实中的使用提出了几点思考。对可视化而言,重点讨论了三维动态显示存在的问题,提出应该增强虚拟现实中的多尺度表达,重视属性信息的表达。对声音的使用而言,在声音变量的描述方法及人耳听觉感知机制的基础上,重点介绍了声音在虚拟现实中的特殊作用。

Based on the status of virtual reality,the paper mainly brings forwards some concerns with the visualization and sound express in virtual reality.For the visualization,some deficiencies in the current 3Dand dynamic virtualization are pointed out,and the limitation of LOD in 3Ddisplay should be overcome to enhance multi-scale expression in virtual reality,and the internal attributes expression should also be emphasized.For the sound,the paper introduces sound variables and the mechanism of human sound perception,and the special functions of sound are also listed.All the viewpoints above are aimed to enhance the effect of virtual reality,and build the better spatial cognition for the users.
