When image on CRT is blurred, the correct percent is increased with the increase of target size and contrast between target and its background. In visual search for the low vision with opthalmological diseases, the reaction time is longer than that of normal subjects. Furthermore, if contrast between Chinese characters and its background is increased, the reaction time is shorten. Post operative visual perception in the early blind of three subjects was examined. Perception of subjective contour is limitted, but shadow is differenciated from targets. One of three subjects perceived the depth from perspective patten with shade. In tactual perception, the surface with a cavity was observed by active touch. The optimum tacile illusion is observed, when cavity and finger is similar in curvature. The ATM with tactile signs has been developped. The blind subjects evaluated that its machine is useful. Tactile reaction time is about 10s at first time. Two alternative displays have been developed for blind computer user. Subjects who had experience in the mouse operation used tactile assisting devise better than auditory device only.

当CRT上的图像变得模糊时，目标尺寸的增加和目标与其背景之间的对比度增加了正确的百分比。在视觉搜索视力较低的眼科疾病中，反应时间比正常受试者的反应时间更长。此外，如果汉字及其背景之间的对比增加，则反应时间缩短。检查了三个受试者的早期盲人手术视觉感知。主观轮廓的感知受到限制，但阴影与目标有所不同。三个受试者之一从透视上看到了深度，并带有阴影。在触发下，通过主动触摸观察到具有空腔的表面。当腔和手指在曲率上相似时，观察到了最佳的含义幻觉。已经开发了带有触觉标志的ATM。盲人评估其机器很有用。触觉反应时间大约是10秒钟。为盲目的计算机用户开发了两个替代显示。在鼠标操作方面有经验的受试者使用的触觉有助于设计比听觉设备更好地设计。
