我们推出了一种可穿戴的前臂增强装置，可以通过在皮肤上施加剪切力来重现自然的触觉。与之前的方法相比，我们将轻质且可拉伸的 3x3cm 膏药以矩阵形式排列在皮肤上。各个膏药中嵌入形状记忆合金（SMA）线，以产生剪切力。我们的设计基于一系列研究，调查了前臂上不同尺寸、间距和膏药附件的可感知性。我们的矩阵排列可以感知触摸，例如感觉手腕被抓住或手臂被抚摸。用户认为重新创建的触摸感觉与真实触摸非常相似 (4.1/5)。即使没有视觉表示，用户也能够正确区分它们，总体准确率为 94.75%。最后，我们探索了两个用例，展示了如何通过在前臂上体验重建的触觉来增强 AR 和 VR 的能力。
We present a wearable forearm augmentation that enables the recreation of natural touch sensation by applying shear-forces onto the skin. In contrast to previous approaches, we arrange light-weight and stretchable 3x3cm plasters in a matrix onto the skin. Individual plasters were embedded with lines of shape-memory alloy (SMA) wires to generate shear-forces. Our design is informed by a series of studies investigating the perceptibility of different sizes, spacings, and attachments of plasters on the forearm. Our matrix arrangement enables the perception of touches, for instance, feeling ones wrist being grabbed or the arm being stroked. Users rated the recreated touch sensations as being fairly similar to a real touch (4.1/5). Even without a visual representation, users were able to correctly distinguish them with an overall accuracy of 94.75%. Finally, we explored two use cases showing how AR and VR could be empowered with experiencing recreated touch sensations on the forearm.
