盲人图形学的一个问题是，我们很少有关于他（她）如何通过触摸获得图形信息的数据。在本文中，我们提出了一种使用相机（眼睛跟踪的模拟物）跟踪他（她）指尖在图形材料上的触摸点的方法，用于分析图像获取过程。我们展示的方法上的边缘概述的触觉图片的花，并表明它产生的基本功能的原始概述花的实验依赖于一个视力受损的主题。作为第3.1节中的远程链接材料，我们描述了在线触觉地图的其他应用，其中我们引入了使用跟踪技术在触摸触觉图片和查看图形图片之间共享位置信息的想法。
One of the problems regarding graphics for blind individual is that we have few data on how he (she) acquires graphical information through touching. In this article, we propose a method of tracking the touch point of his (her) fingertip on graphics material using cameras (an analog of eye-tracking) for analyzing the image acquisition process. We exhibit the method on an edge-outlined tactile picture of a flower and show that it yields basic features of the original outlined flower by an experiment relying on a visually impaired subject. As a linked yet remotely material in Section 3.1 we describe our other application of online tactile map in which we have introduced the idea of sharing positional information between touching a tactile picture and looking into a graphical picture using a tracking technology.
