项目摘要

This study was a fundamental one for showing the informational conditions of tactile graphics which were easily for students who were bind to access them. It had two objectives ; (1) to show requirements for easy understanding of dotted or embossed graphics which were made by modifying visual graphics, and (2) to show requirements of the least additional verbal-information for supplement of information lost by modifying visual graphics.On results of the study concerning in objectives (1), we found as follows : 1) Understanding of tactile graphics depended on developmental level of haptic perception in students, 2) Conversion to tactile graphics was effective in visual graphics with low familiarity, 3) Facial expression, movement and so on could be omitted in tactile graphics, 4) Whether was casy understanding in tactile graphics with side view or with front view was depended on each objects, and 5) Illusion of line length just like visual perception was also found in haptic perception and further study was necessary on it.On results of the study concerning in objectives(2), we found as follows : 1) There were visual graphics with easy access for blind students which were only converted to verbal information but not to convert to tactile graphics, 2) The effects of categorical information as additional verbal-information was reduced in graphics with complex pictorial structure, and 3) Graphics with low familiarity was more fitted to explanatory information than to categorical information as additional verbal-information, and 4) The more modified in tactile graphics, the more effective the additional verbal-information detailed was.

这项研究是显示触觉图形的信息条件的基本研究，这些条件很容易适合有依据的学生。它有两个目标；（1）显示出对通过修改视觉图形制作的虚线或浮雕图形的轻松理解的要求，以及（2）显示最少额外的言语信息的要求，以补充通过修改视觉图形而丢失的信息。关于目标（1）的研究，我们发现：1）对触觉图形的理解取决于学生的触觉感知的发展水平，2）转换为触觉图形在熟悉程度低的视觉图形中有效，3）面部表达，运动，运动，运动等等，可以在触觉图形中省略4）4）是否在带有侧视图的触觉图形中是casy的理解或前视图依赖于每个对象，而5）线长度的幻觉，就像视觉感知在触觉感知和关于目标的研究结果（2），我们发现：1）有视觉图形，可轻松访问盲人学生，但仅转换为口头信息，但不能转换为触觉图形，，2）在具有复杂绘画结构的图形中，分类信息作为额外的言语信息的影响，以及3）具有低熟悉程度的图形比解释性信息更合适，而不是将其分类为额外的口头信息，而4）越多）修改了触觉图形，详细介绍的额外口头信息越有效。
