The purpose of this study was (1) to establish the virtual-reality environment in which visual information such as object size, color, texture, and shape were easily and accurately manipulated independent of other physical and haptic information such as object weight, surface slipperiness, inertia tensor, center of gravity, and mass distribution which affects human perception and movement more strongly than visual information, and (2) to investigate the roles of visual information, such as object size especially in this study, on the perceptual system of heaviness and force generating system of lifting movement. With regard to the first purpose, the virtual-environment called “Virtual Object Lab System" has been established at The Laboratory of Behavioral Neuroscience in Tezukayama University, in collaboration of Dr. Yoshifumi Kitamura, Department of Multimedia Engineering of Graduate School of Osaka University, and Dr. Christine L. MacKenzie, School of Kinesiology of Simon Fraser Univ … More ersity, with addition of some useful devices. However, some difficulties also have been found in operating for the experiment due to its poor resolution of position sensing by ultrasonic waves, thus the improvement has been required. Instead, with regard to the second purpose, effects of visual size on perceiving system of heaviness were investigated using the size-weight illusion paradigm (Charpentier 1891) under the Virtual Hand Lab System. 17 subjects compared difference in heaviness of two augmented cubes with identical weight but different visual sizes under the Virtual Hand Lab System. Results indicated that visual size information was systematically affected perceived system. That is, the lifted object was perceived to be lighter as object size cues increased. Follow-up tests showed occurrence of the illusive perception was significantly correlated with subject's sensitivity to discriminate WEIGHT, but not with sensitivity to discriminate VISUAL SIZE. Conclusively, the size-weight illusion induced by visual size cues is sensory based, and depends on an individual's integrated perception based on multimodal sensory information. Less

这项研究的目的是（1）建立虚拟真实环境，在这些环境中，诸如对象的大小，颜色，纹理和形状等视觉信息可以轻松，准确地操纵，独立于其他物理和触觉信息，例如物体的重量，表面slipsiliness，protia Tensor，重心，引力中心和质量分布，从而影响人类的感知和移动，并在这些信息上尤其强烈地调查了视觉信息，并在视觉上进行视觉信息，并（2）研究，（2），并（2）研究，（2）天堂的感知系统和力量产生的起重运动系统。关于第一个目的，在Tezukayama大学的行为神经科学实验室已经建立了称为“虚拟对象实验室系统”的虚拟环境，与大阪大学研究生院的多媒体工程系Yoshifumi Kitamura合作，以及MACKENZIE L. MACKENZIE，SIMBENZIE of SIMBERIV，KISTINIL OF KISTIN of KISTIN of KISTINIL of KISTIN of KISTINIL of KISTINIL INIVIT INIFIT ...设备。但是，由于超声波对位置敏感性的分辨率较差，因此在实验操作中发现了一些困难，因此需要改进。相反，关于第二个目的，使用虚拟手部实验室系统下的大小幻觉范式（Charpentier 1891）研究了视觉大小对天堂感知系统的影响。 17名受试者比较了两个增强立方体的天堂差异，其重量相同，但在虚拟手部实验室系统下的视觉尺寸不同。结果表明，视觉尺寸信息受到系统影响的感知系统。也就是说，随着对象大小提示的增加，提起的对象被认为更轻。显示的说明性感知发生的后续测试与受试者对区分体重的敏感性显着相关，但对区分视觉尺寸的敏感性没有。结论性地，视觉尺寸提示引起的大小重量幻觉是基于感觉的，并且取决于基于多模式感觉信息的个人的综合感知。较少的
