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.

这项工作探讨了用户在接触虚拟现实时对化身虚拟手偏移的敏感度如何变化。我们在 4 周的时间内使用两种选择的强制选择 (2-AFC) 设计进行了一项实验，分为四个阶段。每个会话中的试验有各种八个偏移距离与八个偏移方向（跨二维平面）配对。虽然我们没有找到证据表明用户随着时间的推移对偏移变得更加敏感，但我们确实找到了行为变化的证据。具体而言，随着课程的进行，参与者的头手协调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-动作协调的长期校准的理解。
