The tactile directional map is similar to regular directional maps in function. Yet, due to the fact that it requires specified Braille explanation and larger tactile elements, the information density on the tactile directional map is relatively lower. Consequently, a tactile directional map is normally not as delicate and not as comprehensive as a regular directional map. The purpose of this study is to examine the appropriate size of various elements on the tactile directional map and to develop a set of design principles in order to create one that better meets the need. It first explores the way the visually impaired use the tactile directional map and inquires about their views and suggestions.

一般导引地图上有指示性图示，超越文字的藩篱，能让大多数人能理解，且可简化版面的设计；然而触觉地图虽与一般地图相类似，但增加了点字说明和一些触觉元素，可是却鲜少有图像，这是由於点字和一些触觉元素的特性使然，因而使得触觉导引地图上的资讯密度相对较低，造成触觉导引地图缺乏像明眼人导引地图一样地设计完善，也没解释这麽清楚、更缺少图像化的设计，若是维持和一般导引地图相同的资讯密度，则触摸导引地图的面积会过大，超出了一般人手部可触及的范围，造成了视障者触读的不便，这都会使得资讯残缺及迷失，甚而产生一些不可知的危险状况。
