摘要

触觉反馈在虚拟现实（VR）交互中起着至关重要的作用，有助于提高用户操作的精度，增强用户体验的沉浸感。虚拟环境中的触觉反馈主要是通过接地力或振动反馈装置来实现的。然而，在活动空间和反馈真实性方面还需要改进。方法我们设计了一种轻巧灵活的触觉反馈手套，可以通过动觉和振动反馈对VR环境中的物体进行触觉渲染，从而使用户享受丰富的虚拟钢琴演奏体验。手套的动觉反馈依赖于拉线机构，该机构旋转并拉动连接在其上的两条电缆，从而改变产生的力的大小，以模拟物体的硬度或柔软度。振动反馈是由嵌入手套指尖底部的小型振动电机提供的。我们在虚拟环境中设计了一个弹钢琴的场景，并进行了用户测试。评估标准是清晰、现实、享受和满意度。结果共有14名受试者参与了测试，结果表明，我们提出的手套在四个评价指标上的得分明显高于无反馈和振动反馈方法。结论我们提出的手套可以显著增强用户与虚拟物体交互时的体验。

A haptic feedback glove for virtual piano interaction

Background

Haptic feedback plays a crucial role in virtual reality (VR) interaction, helping to improve the precision of user operation and enhancing the immersion of the user experience. Instrumental haptic feedback in virtual environments is primarily realized using grounded force or vibration feedback devices. However, improvements are required in terms of the active space and feedback realism.

Methods

We propose a lightweight and flexible haptic feedback glove that can haptically render objects in VR environments via kinesthetic and vibration feedback, thereby enabling users to enjoy a rich virtual piano-playing experience. The kinesthetic feedback of the glove relies on a cable-pulling mechanism that rotates the mechanism and pulls the two cables connected to it, thereby changing the amount of force generated to simulate the hardness or softness of the object. Vibration feedback is provided by small vibration motors embedded in the bottom of the fingertips of the glove. We designed a piano-playing scenario in the virtual environment and conducted user tests. The evaluation metrics were clarity, realism, enjoyment, and satisfaction.

Results

A total of 14 subjects participated in the test, and the results showed that our proposed glove scored significantly higher on the four evaluation metrics than the no-feedback and vibration feedback methods.
