本研究比较了VR中手部追踪与控制器输入及其对应虚拟化身组合对目标获取性能的影响，发现手部追踪受益于任何视觉表征，而控制器在不匹配化身时性能下降更显著。
AI 中文摘要
先前的研究表明，常见的VR输入设备（如控制器或手部追踪）与其视觉表征（例如手部或控制器虚拟化身）之间的一致性会影响用户体验和性能。然而，输入-化身组合的具体效果仍未得到充分探索。我们研究了常见输入设备（手部追踪和控制器）和视觉表征（手部和控制器虚拟化身）对目标获取任务中性能和感知成功的影响。我们在16种输入、化身和目标尺寸的组合中包含了抓取和捏取手势。结果表明，手部追踪受益于任何形式的视觉表征——即使不匹配——与没有化身相比，准确率提高高达5.8%，这可能是由于在缺乏物理道具的情况下依赖视觉反馈。控制器通常更受青睐，并提供更快的任务完成速度。然而，不匹配的化身对控制器有更强的负面影响，特别是当虚拟手势与物理动作不对齐时，与匹配条件相比准确率下降5.6%——这表明不准确的反馈可能比完全没有化身反馈更具干扰性。
英文摘要
Previous research suggests that the congruency between common VR input devices - such as controllers or hand tracking - and their visual representations (e.g., hand or controller avatars) influences user experience and performance. However, the specific effects of input-avatar combinations remain underexplored. We study the effects of common input devices (hand tracking and controllers) and visual representations (hand and controller avatars) on performance and perceived success in target acquisition tasks. We included both grasping and pinching gestures across 16 combinations of input, avatar, and target size. Results indicate that hand tracking benefits from any form of visual representation - even when mismatched - achieving up to 5.8% greater accuracy compared to having no avatar, likely due to its reliance on visual feedback in the absence of a physical prop. Controllers were generally preferred and offered faster task completion. However, mismatched avatars had a stronger negative effect with controllers, particularly when the virtual gesture did not align with the physical action, leading to a 5.6% drop in accuracy compared to the matched condition - suggesting that inaccurate feedback can be more disruptive than having no avatar feedback at all.
