Isaka et al. developed a naked-eye stereoscopic viewing system by inducing motion parallax through the orthogonal arrangement of two general-purpose display monitors and combining anamorphosis, which is known as a monocular illusion expression, with tracking of the user’s line of sight. However, the stereoscopic effect perceived with this system may possibly be degraded when using small display monitors due to the effect of binocular disparity. In this paper, we aim at pinpointing the effect of anamorphosis by identifying the difference in the contribution of the two eyes in recognizing the composition of the displayed space. We empirically proved that rather than tracking the dominant eye, it is possible to pinpoint the effect and to improve the sense of presence by placing “cyclopean eye” at a certain internal position between the two eyes to obtain proper anamorphosis. An example of porting the proposed method to a commodity laptop PC with a foldable display is also presented.
