在本文中，我们讨论了基于计算机的触觉图的设计与我们的初步实验结果的支持下，盲人和视障人士。由于视觉障碍使数据可视化技术不适合盲人，我们正在开发一个系统，可以通过触觉和音频媒体访问图形。讨论了人的触觉感知与力反馈装置模拟的感觉之间的差距。我们的策略，以解决力反馈装置的局限性所带来的技术困难进行了解释。基于盲人和视力正常的人进行的实验结果，我们提出了两种技术：雕刻和使用纹理来模拟触觉图上的曲线。在我们的系统中，表面属性和听觉线索的整合，以协助盲人用户探索触觉图。
In this paper we discuss the design of computer-based haptic graphs for blind and visually impaired people with the support of our preliminary experimental results. Since visual impairment makes data visualisation techniques inappropriate for blind people, we are developing a system that can make graphs accessible through haptic and audio media. The disparity between human haptic perception and the sensation simulated by force feedback devices is discussed. Our strategies to tackle technical difficulties posed by the limitations of force feedback devices are explained. Based on the results of experiments conducted on both blind and sighted people, we suggested two techniques: engraving and the use of texture to model curved lines on haptic graphs. Integration of surface property and auditory cues in our system are proposed to assist blind users in exploring haptic graphs.
