Three-dimensional (3D) displays have become important for many applications including vision research, surgical training, medical imaging, virtual prototyping, scientific visualization, and others. In many of these applications, it is necessary for the graphic image to accurately depict the 3D structure of the portrayed object. Unfortunately, the perception of 3D structures in 3D displays is often distorted by the reality depicted in the displays. The effects of these conflicts may affect binocular fusion and may cause visual fatigue. The scope of the vergence–accommodation conflict has been studied extensively to reveal how the distortion in 3D structure happens. The purpose of this work was to study the phenomenon of vergence–accommodation conflict by comparing the theoretical eye vergence angle and gaze-based eye vergence angle based on eye tracker gaze data. The results indicated that the gaze-based eye vergence angle was largest at the greatest parallax. The result also revealed that the eye vergence angle accuracy was significantly highest at the nearest parallax. The accuracy of virtual objects is generally improved when virtual objects are put near the screen and in the middle. Based on the results of this study, we can gain a greater understanding of the vergence–accommodation conflict in the stereoscopic environment.
