The purpose of this study was for proposing method of producing highly discriminable TRUCT (Transparent-Resinous-Ultraviolet-Curing-Type) Braille, providing TRUCT Braille with a discriminating assistive tool for Braille learners, and getting fundamental data to make a contribution to the establishment of Japanese Industrial Standards (JIS) related to display methods for tactile guide maps.Regarding TRUCT Braille, we quantitatively examined the influence of 3 factors : i, e., Braille pattern (dot-distance, dot-height) ; base material and forefinger slipperiness, on discriminability of TRUCT Braille. Firstly, we found the basic TRUCT Braille patterns that are easy for Braille beginners to discriminate, and TRUCT Braille printing-conditions that have no influence on discriminability of TRUCT Braille. As some makers could refer to our findings in printing TRUCT Braille, the findings are fully evaluated. Secondly, it was found that the discriminability of TRUCT Braille is influenced by the … More forefingers' slipperiness and it becomes easier to discriminate them when Braille learners' forefingers are covered by plane-weaved nylon as their forefingers slide more smoothly. In addition, we produced a finger cover made of polyester non-woven fabric that allows the signals for identifying each dot easier to transmit through the interface material than through nylon. We also found that wearing polyester non-woven fabric finger cover enables the Braille learners to discriminate TRUCT Braille more efficiently. After some years, we may put into practical use this finger cover as TRUCT Braille discriminating assistive tool for Braille learners in Japan.Regarding tactile guide map, we examined the influence of tactile symbol size on their discriminability. The relation between each tactile symbol size and discrimination time became clear. This data might be helpful in efforts to derive a standardized method of displaying tactile guide maps. JIS enacted display methods of tactile guide maps in 2007 March. As JIS come up for review once every five years, we will continuously research tactile guide map usage. In this experiment, we used test-pieces made by a screen printing technique. We think that tactile symbol shapes other than these three shapes, methods of production and type of base material (such as paper, metal and plastics) will influence discriminability. Further research is necessary to investigate the effects of several factors on the discriminability of tactile symbols. Less

本研究的目的是提出一种高分辨结构(Transparent-Resinous-Ultraviolet-Curing-Type)盲文的制作方法，为盲文学习者提供一个辨别盲文的辅助工具，并为制定与触觉导图显示方法相关的日本工业标准提供基础数据。在结构盲文方面，我们定量考察了盲文图案(点距、点高)、基础材料和食指滑度3个因素对结构盲文辨别力的影响。首先，我们找到了盲文初学者容易辨别的基本结构盲文图案，以及结构盲文印刷--这些条件对结构盲文的辨别能力没有影响。由于一些制造商可以参考我们在印刷盲文中的发现，这些发现得到了充分的评估。其次，发现结构盲文的可区分性受…的影响当盲文学习者的食指被平面编织的尼龙覆盖时，食指滑得更顺畅，更容易辨别。此外，我们还生产了一个由聚酯无纺布制成的指套，它允许识别每个点的信号更容易通过接口材料传输，而不是通过尼龙。我们还发现，佩戴涤纶非织造布指套可以使盲文学习者更有效地辨别盲文。几年后，我们可以将这种指套作为日本盲文学习者的结构性盲文辨别辅助工具投入实际使用。针对触觉导图，我们考察了触觉符号大小对其辨别能力的影响。每个触觉符号的大小与辨别时间之间的关系变得清晰。这些数据可能有助于推导出一种显示触觉导引地图的标准化方法。JIS于2007年3月颁布了触觉导航图的显示方法。随着JIS每五年提交一次审查，我们将继续研究触觉导航地图的使用情况。在这个实验中，我们使用了由丝网印刷技术制成的试件。我们认为，除了这三种形状外，触觉符号的形状、生产方法和基材的类型(如纸张、金属和塑料)都会影响辨别能力。有必要进一步研究几个因素对触觉符号辨别能力的影响。较少
