With advances in mobile computing and virtual/augmented reality technologies, communicating through touch using wearable haptic devices is poised to enrich and augment current information delivery channels that typically rely on sight and hearing. To realize a wearable haptic device capable of effective data communication, both ergonomics and haptic performance (i.e., array size, bandwidth, and perception accuracy) are essential considerations. However, these goals often involve challenging and conflicting requirements. We present an integrated approach to address these conflicts, which includes incorporating multilayered dielectric elastomer actuators, a lumped-parameter model of the skin, and a wearable frame in the design loop. An antagonistic arrangement-consisting of an actuator deforming the skin-was used to achieve effective force transmission while maintaining a low profile, and the effect of the wearable frame and structure was investigated through lumped-model analysis and human perception studies.
随着移动计算以及虚拟/增强现实技术的进步，使用可穿戴触觉设备通过触摸进行通信，有望丰富和扩展当前通常依赖视觉和听觉的信息传递渠道。为了实现一种能够进行有效数据通信的可穿戴触觉设备，人体工程学和触觉性能（即阵列大小、带宽和感知精度）都是必须考虑的因素。然而，这些目标往往涉及具有挑战性且相互冲突的要求。我们提出了一种综合方法来解决这些冲突，该方法包括在设计环节中纳入多层介电弹性体致动器、皮肤的集总参数模型以及可穿戴框架。采用一种由使皮肤变形的致动器组成的对抗式布局，以在保持低外形的同时实现有效的力传递，并通过集总模型分析和人体感知研究，对可穿戴框架和结构的效果进行了研究。
