虚拟环境中的视觉心理研究

A Study on Visual Psychology in Virtual Environment

结合Tsunehiro Takeda等人针对视觉功能的试验曲线,对虚拟环境所运用的显示技术,如透视、浓淡处理、运动视差以及双眼视差等对视觉心理的影响进行了详细论述,并分析了作为影响视觉心理的生理基础---双眼调节和辐辏功能,在观看图象期间所发生的变化,着重分了视差原理中调节和辐辏的状态对视觉心理,尤其是深度感知方面的影响。并由此从理论上得出了这样的结论,即在虚拟环境中,虚拟空间是一个深度压缩了的空间。

By combining with the experimental vision curves given by Tsunehiro Takeda, the paper discusses the influence upon visual psychology by display technique with more details such as perspective, shading, motion cue, and parallax etc. in virtual environment, analyzes the change of convergence and accommodation, which are the physiology basis of visual psychology, during watching images, especially analyzes the effect of the status of convergence and accommodation toward three dimensional depth perception when looking at stereoscopic images. At last, the authors make a conclusion that virtual environment is a shortened space based on theory.
