Abstract
The utilization of 3D displays has become significant in various fields such as vision research, medical imaging, surgical training, scientific visualization, virtual prototyping, and other related applications. 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 extensive study of the vergence-accommodation conflict has shed light on the distortion in 3D structure. In this study, the aim was to investigate this phenomenon by comparing the theoretical eye vergence angle with the gaze-based eye vergence angle using eye tracker gaze data. The findings showed that the gaze-based eye vergence angle was largest at the greatest parallax, indicating a correlation between parallax and vergence angle. Furthermore, the results revealed that the accuracy of the eye vergence angle was highest at the nearest parallax, suggesting that virtual objects placed closer to the screen and in the middle generally exhibited improved accuracy. These findings contribute to a better understanding of the vergence-accommodation conflict in stereoscopic environments, providing insights that can inform the design and development of virtual reality systems.
