We present a novel input/output device to display the tactile properties of surface materials. The proposed Tactile Computer Mouse (TCM) is equipped with a series of actuators that can create perceptually relevant tactile cues to a user. The display capabilities of our TCM match the major tactile dimensions in human surface material perception, namely, hardness, friction, warmth, microscopic roughness, and macroscopic roughness. The TCM also preserves necessary interaction capabilities of a typical computer mouse. In addition to the TCM design, we introduce data acquisition procedures and concepts that are necessary to derive a parametric representation of a surface material and further demonstrate the corresponding rendering approach on the TCM. We conducted subjective experiments to determine tactile property ratings of real materials, perceived property ratings using the TCM, and how precisely subjects match the real materials to corresponding virtual material representations using the TCM in the absence of visual and audible clues. Our experimental results show that our TCM successfully displays the five fundamental tactile dimensions and that the twenty participants were able to perceive the TCM-produced virtual surface material tactile sensations with a recognition rate of 89.6 percent for ten different materials.
我们提出了一种新颖的输入/输出设备来显示表面材料的触觉特性。所提出的触觉计算机鼠标 (TCM) 配备了一系列致动器，可以向用户创建感知相关的触觉提示。我们的 TCM 的显示能力与人类表面材料感知中的主要触觉维度相匹配，即硬度、摩擦、温暖、微观粗糙度和宏观粗糙度。TCM 还保留了典型计算机鼠标的必要交互功能。除了 TCM 设计，我们还介绍了数据采集程序和概念，这些程序和概念对于得出表面材料的参数表示以及进一步在 TCM 上演示相应的渲染方法是必要的。我们进行了主观实验，以确定真实材料的触觉属性评级、使用 TCM 感知的属性评级，以及在没有视觉和听觉线索的情况下，受试者如何使用 TCM 将真实材料精确匹配到相应的虚拟材料表示。我们的实验结果表明，我们的 TCM 成功地显示了五个基本的触觉维度，二十名参与者能够以 89.6%的识别率感知 TCM 产生的十种不同材料的虚拟表面材料触觉感觉。
