人们还没有很好地理解沉浸式虚拟环境（VE）中低估自我中心距离的倾向。然而，以前的研究（A。R. Richardson & D. Waller，2007）已经证明，在做出距离判断之前与VE进行短暂的交互可以有效地消除随后的低估。在这里，作者研究的机制，潜在的VE互动的影响和条件，可能会引起it.In实验1，互动后与沉浸式VE，参与者往往高估的距离在物理世界中，这表明，互动涉及的感知运动系统的重新校准。实验2表明，视觉信息是没有必要的（和身体为基础的信息是必要的）在互动期间，它有一个积极的影响，随后的距离估计精度。实验3表明，互动任务不需要目标导向，以有效。
The tendency to underestimate egocentric distances in immersive virtual environments (VEs) is not well understood. However, previous research (A. R. Richardson & D. Waller, 2007) has demonstrated that a brief period of interaction with the VE prior to making distance judgments can effectively eliminate subsequent underestimation. Here the authors examine the mechanism underlying the effect of VE interaction and the conditions that may give rise to it. In Experiment 1, after interacting with an immersive VE, participants tended to overestimate distances in the physical world, indicating that the interaction involved a recalibration of the perceptual-motor system. Experiment 2 demonstrates that visual information is not necessary (and that body-based information is necessary) during the interaction period for it to have a positive effect on subsequent distance estimation accuracy. Experiment 3 illustrates that the interaction task does not need to be goal directed in order to be effective.
