论文摘要
在典型的空中触觉系统中，聚焦的空中超声超声为裸露的皮肤上的局部区域提供颤音。在此，提出了提出戴着网格织物手套的手的热感觉的方法。这项研究中使用的手套是具有吸收特征的市售网状织物手套，例如棉花手套，没有任何其他设备，例如毛发元素。这项研究中提出的方法还可以通过改变超声辐射模式来提供纤维ac骨的感觉。在本文中，我们报告了有关该方法的基本实验研究。通过进行热测量，我们通过集中的空气寄宿超声照射来评估手套和皮肤表面上的局部热量产生。此外，我们进行了感知实验，从而确认所提出的方法同时产生了热和纤维骨架感觉。此外，通过改变超声辐射模式，在一定程度上选择性地提供了这些感觉。这些结果证明了我们方法的有效性及其在空中触觉应用中的可行性。
In a typical mid-air haptics system, focused airborne ultrasound provides vibrotactile sensations to localized areas on a bare skin. Herein, a method for displaying thermal sensations to hands where mesh fabric gloves are worn is proposed. The gloves employed in this study are commercially available mesh fabric gloves with sound absorption characteristics, such as cotton work gloves without any additional devices such as Peltier elements. The method proposed in this study can also provide vibrotactile sensations by changing the ultrasonic irradiation pattern. In this paper, we report basic experimental investigations on the proposed method. By performing thermal measurements, we evaluate the local heat generation on the surfaces of both the glove and the skin by focused airborne ultrasound irradiation. In addition, we performed perceptual experiments, thereby confirming that the proposed method produced both thermal and vibrotactile sensations. Furthermore, these sensations were selectively provided to a certain extent by changing the ultrasonic irradiation pattern. These results validate the effectiveness of our method and its feasibility in mid-air haptics applications.
