This paper investigates the relationship between fine motor skill training in VR, haptic feedback, and physiological arousal. To do so, we present the design and development of a motor skill task (buzzwire), along with a custom vibrotactile feedback attachment for the Geomagic Touch haptic device. A controlled experiment following a between-subjects design was conducted with 73 participants, studying the role of three feedback conditions - visual/kinesthetic, visual/vibrotactile and visual only - on the learning and performance of the considered task and the arousal levels of the participants. Results indicate that performance improved in all three feedback conditions after the considered training session. However, participants reported no change in self-efficacy and in terms of presence and task load (NASA-TLX). All three feedback conditions also showed similar arousal levels. Further analysis revealed that positive changes in performance were linked to higher arousal levels. These results suggest the potential of haptic feedback to affect arousal levels and encourage further research into using this relationship to improve motor skill training in VR.

触觉反馈、表现和唤醒：沉浸式 VR 运动技能训练任务的比较研究。

本文研究了 VR 中的精细运动技能训练、触觉反馈和生理唤醒之间的关系。为此，我们介绍了运动技能任务（buzzwire）的设计和开发，以及用于 Geomagic Touch 触觉设备的定制振动触觉反馈附件。对 73 名参与者进行了一项遵循受试者间设计的对照实验，研究三种反馈条件（视觉/动觉、视觉/振动触觉和仅视觉）对所考虑任务的学习和表现以及参与者的唤醒水平的作用。结果表明，经过考虑的培训课程后，所有三种反馈条件下的表现均有所提高。然而，参与者报告自我效能、存在感和任务负荷没有变化（NASA-TLX）。所有三种反馈条件也显示出相似的唤醒水平。进一步的分析表明，绩效的积极变化与更高的唤醒水平有关。这些结果表明触觉反馈可能会影响唤醒水平，并鼓励进一步研究利用这种关系来改善 VR 中的运动技能训练。
