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进行的点缀或浮雕图形的简化要求，以及（2）以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来补充信息丢失的信息。在目标的结果中，有关目标的结果（1），我们发现了以下内容：1）对触觉图形的了解有效地依赖于触觉图形，这是对触觉层面的理解，这些知识依赖于触觉层面，这是对触觉层面的理解。熟悉程度低，3）触觉图形中可以省略面部表情，移动等图形，4）4）是否在触觉图形中了解了带有侧视图的触觉图形或前视图或具有正面视图的图形。盲人学生仅转换为言语信息，但不能转换为触觉图形，2）分类信息的效果随着具有复杂绘画结构的图形减少了额外的言语信息，而3）具有较低熟悉的图形更适合解释性信息，而不是分类信息，而不是分类信息，因为其他语言信息以及4）在触觉中更改的详细信息，更详细地详细说明了详细的详细信息。
