Abstract

This paper presents a haptic stylus interface with a built-in compact tactile display module and an impact module as well as empirical studies on Braille, button, and texture display. We describe preliminary evaluations verifying the tactile display's performance indicating that it can satisfactorily represent Braille numbers for both the normal and the blind. In order to prove haptic feedback capability of the stylus, an experiment providing impact feedback mimicking the click of a button has been conducted. Since the developed device is small enough to be attached to a force feedback device, its applicability to combined force and tactile feedback display in a pen-held haptic device is also investigated. The handle of pen-held haptic interface was replaced by the pen-like interface to add tactile feedback capability to the device. Since the system provides combination of force, tactile and impact feedback, three haptic representation methods for texture display have been compared on surface with 3 texture groups which differ in direction, groove width, and shape. In addition, we evaluate its capacity to support touch screen operations by providing tactile sensations when a user rubs against an image displayed on a monitor.

摘要

本文介绍了一种带有内置紧凑型触觉显示模块和冲击模块的触觉手写笔接口,以及关于盲文、按钮和纹理显示的实证研究。我们描述了初步评估,验证了触觉显示器的性能,表明它能够令人满意地为正常人和盲人呈现盲文数字。为了证明手写笔的触觉反馈能力,进行了一项提供模拟按钮点击的冲击反馈的实验。由于所开发的设备足够小,可以连接到力反馈设备上,因此还研究了其在笔式触觉设备中用于组合力和触觉反馈显示的适用性。笔式触觉接口的手柄被类似笔的接口所取代,以给设备增加触觉反馈能力。由于该系统提供力、触觉和冲击反馈的组合,因此在具有不同方向、凹槽宽度和形状的3个纹理组的表面上,比较了三种用于纹理显示的触觉表示方法。此外,我们通过在用户触摸显示器上显示的图像时提供触觉感受,评估了其支持触摸屏操作的能力。
