先进人机交互界面的开发

【ABSTRACT】

Over the last several decades, human-machine interactions have been limited to vision and audio channels. The introduction of haptics technologies has enabled users to receive mechanical feedbacks in the form of virtual touch. While the rapidly advancing haptics technologies in wearable devices and surface haptic devices have enabled many exciting applications in virtual reality (VR), augmented reality (AR), telecommunication, and teleoperation, they still suffer from issues in bulkiness, comfortability, and consistency. The solutions to these issues lie in the fundamental understanding of the multi-physics interactions in the human-machine interface, which include contact deformation, capillary formation, electric field, heat transfer, material non-linearity, and their complicated coupling effects. In this talk, Dr. Ma will discuss models on the multi-physics interactions in human-machine interface, with a special emphasis on modeling the finger friction variation on textured surfaces. This talk will also include how the multi-physics models have been applied in developing new wearable sensors, actuators, and surface haptics devices. The discussed models lay the foundation to develop haptics artificial materials (metamaterials) that can deliver any desired haptics performances for the next generation of human-machine mechanical interfaces and Metaverse.

在过去的几十年中，人机交互一直局限于视觉和音频通道。引入触觉技术使用户能够以虚拟触感的形式接收机械反馈。虽然可穿戴设备和表面触觉设备中快速发展的触觉技术已经在虚拟现实（VR）、增强现实（AR）、远程通信和远程操作等领域实现了许多令人兴奋的应用，但它们仍然存在着笨重、舒适性差和一致性不足等问题。这些问题的解决方案在于对人机界面中多物理学相互作用的基本理解，包括接触变形、毛细管形成、电场、热传递、材料非线性以及它们复杂的耦合效应。本手机版将讨论人机界面中的多物理学相互作用模型，特别强调对纹理表面上手指摩擦变化建模。此次演讲还将包括多物理学模型在开发新的可穿戴传感器、执行器和表面触觉设备方面的应用。所讨论的模型为开发触觉人机机械界面的下一代可以提供任何所需触觉性能的触觉人工材料（超材料）奠定了基础。

基于折纸结构的多模式柔性驱动与高保真触感交互

【ABSTRACT】

Unlike conventional rigid robots, soft robots have gained significant attention in the robotics community due to their excellent human-robot interaction capabilities. However, achieving similar levels of multimodal, high-performance motion as rigid robots while maintaining the structural compliance of soft robots remains a huge challenge, which is also one of the key limitations preventing soft robots from industrial applications. In this talk, I will introduce design approaches for multimodal soft actuation from three perspectives: how to realize multiple motion modes and high output force with conventional pneumatic methods, how to achieve high positioning accuracy and stiffness tuning through antagonistic actuation, and how to leverage innovative origami structures to enable all-purpose motion modes. Finally, I will discuss the potential of combining origami structures and multimodal soft actuation to enrich haptic interactions in both the virtual world and the physical world, aiming to open new technical pathways in the field of human-robot interaction.

不同于传统刚性机器人，柔性机器人因其优异的人机交互友好性成为了国际机器人学界的热点方向。但如何使柔性机器人在发挥其结构顺应性的同时，兼具如同刚性机器人般的多模态、高性能运动能力，是当前学界与业界的难题，也是制约柔性机器人走向工业应用的核心“硬伤”之一。在本次手机版中，我将从三个方面展开介绍多模式柔性驱动的设计方法，包括如何使用传统气动方法实现多运动模式集成并提升输出力，如何利用拮抗驱动作用实现高精度运动输出与刚度调控，以及如何创新设计折纸结构以进一步实现全运动模式输出。最后，我将分别就利用折纸结构与多模式柔性驱动丰富虚拟世界与现实物理世界的新型触感交互展开讨论，旨在为人机交互领域开拓新的研究方向与技术路线。

全集成可穿戴电触觉界面与个性化虚拟触觉进展

【ABSTRACT】

The haptic interface enhances tactile perception for users in VR/AR, gaming, social media, and robotics. Conventional haptic interfaces are often bulky, grounded or require connection to external instruments. To free users from these constraints, electrotactile technology offers a promising solution. In this talk, I will introduce our recent advances in wearable electrotactile interfaces for hands, along with the personalized virtual touching experiences enabled by this platform. Through the integration of miniaturized wireless microelectronics with ultra-soft, stretchable, bioadhesive and permeable materials, we developed a series of fully integrated haptic interfaces that characterized by an ultra-thin and breathable e-skin form, cable-free operation, stable electrode-skin interface, and sweat-insensitive performance. Additionally, the large-area high density electrodes array facilitates easy calibration of electrotactile thresholds distribution across the whole hand. Our investigation of thresholds revealed significant differences in sensory sensitivity across different parts of the hand and these features vary considerably among individuals. Furthermore, we found that dynamic feedback patterns are significantly easier to distinguish compared to static feedback. Thus, encoding dynamic tactile information into threshold-calibrated stimulation waveforms enables a personalized electrotactile experience for each user. We also demonstrated the potential of personalized electrotactile technology in tactile recovery in hypoesthesia patients. Through these demonstrations, we aim to make enhanced and virtual touching more realistic and accessible to everyone.

触觉界面在VR/AR、游戏、社交媒体和机器人等领域中可增强用户的触觉感知。传统的触觉界面通常体积庞大、需要接地或连接外部设备。与之相比，电触觉技术可能是解决这些限制的可行方案。在这次手机版中，我将介绍我们在手部可穿戴电触觉界面的最新进展，以及借此实现的个性化虚拟触感体验。我们通过微型无线电子，结合柔性可拉伸、生物黏附及透气材料，开发了一系列全集成的触觉界面。该触觉界面具有超薄透气的电子皮肤形态、无线可操作性、稳定的电极-皮肤接口，且不受皮肤出汗影响。此外，其大面积高密度电极阵列令全手的阈值分布校准更加便捷。我们发现，手部不同区域的感知灵敏度存在显著差异，且在个体之间变化很大。同时，动态反馈模式相比静态反馈更容易区分。因此，我们通过基于阈值校准的刺激波形编码动态触觉信息，为每位用户实现了个性化的电触觉体验。此外，我们还展示了个性化电触觉技术在感觉迟钝患者触觉恢复中的潜力。通过这些成果，我们希望增强和虚拟触摸变得更为真实，并能够惠及大众。
