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 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.
