这项工作探讨了当用户接触虚拟现实时，他们对其化身虚拟手部偏移的敏感度如何变化。我们使用两种替代强制选择 (2-AFC) 设计进行了一项为期 4 周的实验，分为四个阶段。每个会话中的试验都有各种八个偏移距离与八个偏移方向（穿过二维平面）配对。虽然我们没有发现证据表明用户随着时间的推移对偏移变得更加敏感，但我们确实发现了行为变化的证据。具体来说，随着课程的进行，参与者的头手协调能力和完成时间显着变化。我们讨论了这两个结果的含义，以及它们如何影响我们对虚拟环境中感知-行动协调的长期校准的理解。
This work explored how users’ sensitivity to offsets in their avatars’ virtual hands changes as they gain exposure to virtual reality. We conducted an experiment using a two-alternative forced choice (2-AFC) design over the course of 4 weeks, split into four sessions. The trials in each session had a variety of eight offset distances paired with eight offset directions (across a two-dimensional plane). While we did not find evidence that users became more sensitive to the offsets over time, we did find evidence of behavioral changes. Specifically, participants’ head–hand coordination and completion time varied significantly as the sessions went on. We discuss the implications of both results and how they could influence our understanding of long-term calibration for perception-action coordination in virtual environments.
