论文摘要
我们建议使用虚拟操作的触觉系统，以提供对用户前臂而不是指尖的反馈。除了用虚拟指尖对操作进行视觉渲染外，我们还采用一种设备在手腕附近的多个点上提供正常或剪切的皮肤拉伸。为了了解设计参数如何影响体验，我们研究了感觉反馈对刚度感知的数量和位置的影响。参与者比较了虚拟物体的刚度值，而触觉手镯则在手腕的背，腹侧或两侧提供了相互作用的反馈。僵硬的判断判断和持续时间以及口头上收集的定性结果表明，在不同位置和多个位置刺激的僵化感知没有显着差异。
We propose a haptic system for virtual manipulation to provide feedback on the user's forearm instead of the fingertips. In addition to visual rendering of the manipulation with virtual fingertips, we employ a device to deliver normal or shear skin-stretch at multiple points near the wrist. To understand how design parameters influence the experience, we investigated the effect of the number and location of sensory feedback on stiffness perception. Participants compared stiffness values of virtual objects, while the haptic bracelet provided interaction feedback on the dorsal, ventral, or both sides of the wrist. Stiffness discrimination judgments and duration, as well as qualitative results collected verbally, indicate no significant difference in stiffness perception with stimulation at different and multiple locations.
