许多老年人执行碰撞避免行为不够（即，频繁的冲突）或无效（即，夸张的行为，以确保避免碰撞）。本研究探讨了使用虚拟现实（VR）模拟的训练系统是否增强了老年人在真实的行走过程中对光圈的VR图像的避碰行为。25名（n =13干预组和n =12对照组）老年人参加。在训练过程中，通过光圈行走的VR图像被投影到大屏幕上。干预组的参与者试图以最小的身体旋转来避免虚拟碰撞，从而通过各种狭窄的孔在现场行走。对照组的参与者在通过一个大光圈的现场行走时保持身体不旋转。在真实的环境中进行的前测和后测表现的比较表明，在训练后，观察到干预组的身体旋转角度显着较小。这表明，训练引导参与者改变他们的行为，试图在真实的行走中有效地移动。然而，碰撞率虽然不显著，但也往往更高，这表明，至少对一些参与者来说，避免碰撞所需的修改太难了。讨论了使用VR环境的学习行为到真实的行走的转移。
Many older adults perform collision-avoidance behavior either insufficiently (i.e., frequent collision) or inefficiently (i.e., exaggerated behavior to ensure collision-avoidance). The present study examined whether a training system using virtual reality (VR) simulation enhanced older adults' collision-avoidance behavior in response to a VR image of an aperture during real walking. Twenty-five (n =13 intervention group and n =12 control group) older individuals participated. During training, a VR image of walking through an aperture was projected onto a large screen. Participants in the intervention group tried to avoid virtual collision with the minimum body rotation required to walk on the spot through a variety of narrow apertures. Participants in the control group remained without body rotation while walking on the spot through a wide aperture. A comparison between pretest and post-test performances in the real environment indicated that after the training, significantly smaller body rotation angles were observed in the intervention group. This suggests that the training led participants to modify their behavior to try to move efficiently during real walking. However, although not significant, collision rates also tended to be greater, suggesting that, at least for some participants, the modification required to avoid collision was too difficult. Transfer of the learned behavior using the VR environment to real walking is discussed.
