项目摘要

Human mechanisms of sensory integration and three-dimensional space cognition in a virtual environment have been sought from the standpoint of information and control engineering, cognitive psychology, animal behavioral science, and brain physiology in order to find a clue to the elucidation of sensations of presence, reality and existence. The target of the study is to establish methods and procedures to measure sensations of presence, reality and existence by clarifying the mechanisms of human sensory integration and three-dimensional space cognition utilizing information and control engineering, cognitive psychology and neuro-physiology. It is also aimed to generate a virtual environment, which is almost like the real environment but can be controlled easily by the computer. Sensation, perception, cognition and behavior mechanisms of human beings and primates in the computer-controlled-virtual environment are being studied by presenting computer-controlled-realistic surroundings and … More measuring the responsive behaviors of human beings or primates in the virtual environment with collaboration of information and control scientists, cognitive scientists and neuro-scientists.As a result, a new paradigm was proposed to elucidate human mechanisms of sensations of presence, reality and existence by observing and measuring human or primate behaviors and physiological indexes in the virtual environment, and its feasibility and effectiveness were proved and demonstrated. According to the proposed paradigm, experimental virtual environment was constructed in which visual and haptic information were integrated to have the sensation of touching object just as was seen. It was also generated and controlled by the computer and have the essence of the real shape. Its effect was quantitatively evaluated through experiments using the experimental apparatus. A clue to the index of sensation of presence was also acquired by measuring body sway caused by virtual centrifugal acceleration induced by vection. In the area of brain physiology, it was found that primates had their cognitive ability of three-dimensional virtual objects made from the disparities by using random-dot stereogram. It was also found that the receptive field of a monkey was extended through the use of tools. Less

从信息与控制工程学、认知心理学、动物行为学和脑生理学的观点出发，对虚拟环境中人的感觉整合和三维空间认知的机制进行了探索，以期找到解释在场、真实和存在感觉的线索。本研究的目的是利用信息与控制工程、认知心理学和神经生理学等学科的知识，通过阐明人类感觉整合和三维空间认知的机制，建立测量存在感、真实感和存在感的方法和程序。它还旨在生成一个虚拟环境，这是几乎像真实的环境，但可以很容易地由计算机控制。计算机控制的虚拟环境中的人类和灵长类动物的感觉、知觉、认知和行为机制正在通过呈现计算机控制的真实环境来研究， ...更多信息通过与信息与控制科学家、认知科学家和神经科学家的合作，测量人类或灵长类动物在虚拟环境中的反应行为，从而提出了一种通过观察和测量人类或灵长类动物在虚拟环境中的行为和生理指标，并论证了其可行性和有效性。根据所提出的范例，实验虚拟环境中，视觉和触觉信息集成，具有触摸物体的感觉，就像看到的。它也是由计算机生成和控制的，具有真实的形状的本质。通过使用该实验装置的实验，定量地评估其效果。通过测量由矢量引起的虚拟离心加速度引起的身体摇摆，也获得了存在感指数的线索。在脑生理学领域，研究发现灵长类动物具有对由视差随机点立体图构成的三维虚拟物体的认知能力。研究还发现，通过使用工具，猴子的感受野得到了扩展。少
