近年来，作为人机界面的一部分，触觉力表示方案的重要性得到了广泛的讨论。在这些方案中，重要的是力的表示是平滑的，这就要求无触觉力的表示具有良好的高频响应。为了满足这一需求，在这项研究中，我们特别注意确保我们的演示设备能够在高达1 kHz的频率下快速响应，并具有从执行器到执行器阶段的力的反向驱动性。我们首先构建了一个简单的触觉显示器的实现，然后将其转换为一个更小、更轻的版本。显示呈现的基础是对手指运动的触觉灵敏度。为了实现这一点，我们的设备使用磁性位置传感器和角度传感器来检测手指的运动。基于这些手指的运动，该装置改变与接触相对应的触觉呈现信息。在一个特别需要快速响应的典型演示实验中，我们研究了利用接触产生的振动感觉来呈现各种木材的感觉的可能性。此外，我们还进行了一个表面粗糙度呈现实验，在实验中，显示操作员追踪一个虚拟墙，并被要求区分五种表面粗糙度。在本文中，我们总结了我们对我们的仪器的特点和功能的评估。©2006 Wiley期刊公司系统比较，37(2):46 - 55,2006；在线发表于Wiley InterScience（）。DOI 10.1002 sscj.20297
The importance of tactilesforce presentation schemes as part of human–computer interfacing has been extensively discussed in recent years. In these schemes it is important that the presentation of force be smooth, which requires that the tactilesforce presentation have good high-frequency response. To address this need, in this research we took special care to ensure that our presentation equipment could respond rapidly at frequencies up to 1 kHz, with backdrivability of the force from the effector to the actuator stage. We first constructed a simple realization of our haptic display, and then converted it to a smaller-scale and lighter-weight version. The basis of the display presentation was tactile sensitivity in response to finger movements. To achieve this, our apparatus uses magnetic position sensors and angle sensors to detect the finger movements. Based on these finger movements, the apparatus makes changes in the tactile presentation information that correspond to the contact. In a typical presentation experiment for which a fast response was especially necessary, we studied the possibility of using the sensation of vibrations generated by contact to present the feel of various kinds of wood. In addition, we performed a surface roughness presentation experiment in which display operators traced a virtual wall and were made to distinguish five kinds of surface roughness. In this paper, we summarize our assessment of the characteristics and functioning of our apparatus. © 2006 Wiley Periodicals, Inc.
