用气压调节的布制触觉装置，让用户在沉浸空间中凭触感感知方向。
Intuitive Directional Sense Presentation to the Torso Using McKibben-Based Surface Haptic Sensation in Immersive Space
- 通过织物气动肌控制气压，实现全身表面触觉引导。
- 实验表明用户可在无视觉条件下准确感知方向，效果显著。
- 适合远程操控、虚拟现实等需非视觉引导的场景。
近年来，沉浸式空间系统在多个领域得到发展。由于沉浸空间包含大量视觉信息，用户常难以获取所需信息。为此，研究者开发了多种触觉引导方法。然而，许多现有方法在触觉感知的直观性方面存在不足，且需要用户适应练习。本研究采用结合织物与麦基本人工肌肉的柔性执行器，作为可穿戴触觉设备，为用户提供大面积、直观的表面触觉反馈，而非局限于局部区域。本文提出一种新型空气压力调节方法，利用可穿戴织物执行器实现全身运动引导。所提系统可在无视觉信息的沉浸空间中有效传递方向感。通过受试者实验与统计分析验证了系统的有效性。最后，在混合现实空间中对用户进行微操作任务的方位引导测试，进一步证明了该系统在远程操作中的应用潜力。
原文摘要 · Abstract (English)
In recent years, systems that utilize immersive space have been developed in various fields. Immersive spaces often contain considerable amounts of visual information; therefore, users often fail to obtain their desired information. Therefore, various methods have been developed to guide users toward haptic sensations. However, many of these methods have limitations in terms of the intuitive perception of haptic sensation and require practice for familiarization with haptic sensation. Fabric actuators are wearable haptic devices that combine fabric and McKibben artificial muscles to provide wearers with surface haptic sensation. These sensations can be provided to a wide area of the body with intuitive perception, instead of only to a part of the body. This paper presents a novel air pressure adjustment method for whole-body motion guidance using surface haptic sensations provided by a wearable fabric actuator. The proposed system can provide users with a directional sense without visual information in an immersive space. The effectiveness of the proposed system was evaluated through subject experiments and statistical data analysis. Finally, a directional sense presentation was conducted for users performing micromanipulations in a mixed-reality space to demonstrate the applicability of the proposed system for teleoperation.
