The awareness of self-position, which refers to the location of our cyclopean eye, is essential to the experience of being immersed and for interacting with a virtual environment. Currently, individual variability in the cyclopean eye location is not considered when presenting virtual reality (VR) content. The effect of the cyclopean eye shift was analyzed with theoretical and experimental methods, and it was found that human vision is sensitive to the visual direction offset caused by the cyclopean eye shift. To compensate for the cyclopean eye shift, an original model is proposed with shifting the 3D camera system accordingly. The proposed method is expected to make all individuals with different cyclopean eye shifts perceive the virtual environment from the same viewpoint as the designer desired and may achieve more accurate interaction.
自我位置感知，即指我们单眼视觉中心的位置，对于沉浸体验以及与虚拟环境进行交互至关重要。目前，在呈现虚拟现实（VR）内容时，并未考虑单眼视觉中心位置的个体差异。通过理论和实验方法分析了单眼视觉中心偏移的影响，结果发现人类视觉对单眼视觉中心偏移引起的视觉方向偏移很敏感。为了补偿单眼视觉中心偏移，提出了一种通过相应地移动3D相机系统的原始模型。预期该方法能使所有具有不同单眼视觉中心偏移的个体从与设计者期望相同的视角感知虚拟环境，并可能实现更精确的交互。
