Virtusphere 新手用户在尝试将其意图转化为虚拟运动时经常会遇到困难。特别是，当用户打算笔直向前行走时，由于行走的机制，界面通常会转向略有不同的方向。为了改进这一点，界面被修改为将用户躯干的方向合并为预期移动方向的指示器。新的界面方案针对基线 Virtusphere 界面进行了测试，显示了训练期间类似的运动性能，但增加了自我报告的自然度，并且在盲行范例期间实现了更准确的遍历，从而促进了轨迹分析。
Novice Virtusphere users often encounter difficulties when attempting to translate their intentions to virtual locomotion movements. In particular, when users intend to walk straight ahead, the interface often veers in a slightly different direction due to the mechanics of walking. In an attempt to improve this, the interface was modified to incorporate the direction of the user's torso as an indicator of intended movement direction. The new interface scheme was tested against the baseline Virtusphere interface, revealing similar movement performance during training, but increased self-reported naturalness, and more accurate traversal during a blind-walking paradigm, facilitating trajectory analysis.
