Abstract

The emergence of vibrotactile feedback in hand wearables enables immersive virtual reality (VR) experience with whole-hand haptic rendering. However, existing haptic rendering neglects inconsistent sensations caused by hand postures. In our study, we observed that changing hand postures alters the distribution of vibrotactile signals which might degrade one's haptic perception. To address the issues, we present HapticPilot which allows an in-situ haptic experience design for hand wearables in VR. We developed an in-situ authoring system supporting instant haptic design. In the authoring tool, we applied our posture-adaptive haptic rendering algorithm with a novel haptic design abstraction called phantom grid. The algorithm adapts phantom grid to the target posture and incorporates 1D & 2D phantom sensation with a unique actuator arrangement to provide a whole-hand experience. With this method, HapticPilot provides a consistent haptic experience across various hand postures is available. Through measuring perceptual haptic performance and collecting qualitative feedback, we validated the usability of the system. In the end, we demonstrated our system with prospective VR scenarios showing how it enables an intuitive, empowering, and responsive haptic authoring framework.

触觉领航
手部可穿戴设备中振动触觉反馈的出现,通过整个手部的触觉渲染实现了身临其境的虚拟现实(VR)体验。然而,现有的触觉渲染忽略了手部姿势造成的不一致感觉。在我们的研究中,我们观察到手部姿势的改变会改变振动触觉信号的分布,这可能会降低人们的触觉感知。为了解决这些问题,我们提出了 HapticPilot,它允许在 VR 中对手部可穿戴设备进行现场触觉体验设计。我们开发了一个支持即时触觉设计的原位创作系统。在创作工具中,我们应用了姿态自适应触觉渲染算法和一种名为幻影网格的新型触觉设计抽象。该算法可根据目标姿势调整幻影网格,并将一维和二维幻影感觉与独特的致动器排列相结合,以提供全手体验。通过这种方法,HapticPilot 可在各种手部姿势下提供一致的触觉体验。通过测量感知触觉性能和收集定性反馈,我们验证了系统的可用性。最后,我们用未来的 VR 场景演示了我们的系统,展示了它是如何实现直观、授权和响应式触觉创作框架的。
