In this Study, we have developed the system to simulate the hierarchical and parallel processing of the human visual system. A particular interest here is the modular architecture of the visual system : the characteristic of each module which is responsible for the processing of motion, depth and shape ; the integration of information provided by parallel pathways to produce a unified perception of an object in 3-dimensional outer world. First, we have developed the apparatus for the measurement of the characteristics of the perception of 3-D space by using the virtual reality system. This enabled us to analyze the perceptual responses for multidimensionally varying stimuli which simulate the stimuli we encounter in every day life. Second, we developed the simulation system to analyze the integration processes of the visual information such as depth, shape and motion in the visual phenomenon of constancy.

在本研究中，我们开发了系统来模拟人类视觉系统的分层和并行处理。这里特别令人感兴趣的是视觉系统的模块化架构：每个模块的特性，负责处理运动、深度和形状；并行路径提供的信息整合，以产生对 3 维外部世界中物体的统一感知。首先，我们开发了利用虚拟现实系统测量3D空间感知特性的装置。这使我们能够分析多维变化刺激的感知反应，模拟我们在日常生活中遇到的刺激。其次，我们开发了仿真系统来分析恒常性视觉现象中深度、形状和运动等视觉信息的整合过程。
