65‐5: Invited Paper:Resolving the Vergence Accommodation Conflict in VR and AR via Tunable Liquid Crystal Lenses

Virtual reality (VR) and augmented reality (AR) head mounted displays project stereoscopic virtual images to the eyes to obtain a three‐dimensional illusion. The mismatch between the vergence and accommodation focus cues, known as the vergence‐accommodation conflict (VAC), can cause physical discomfort and limit the immersive experience of these systems. In AR systems, even monocular vision is affected by the focus mismatch, since the eye cannot focus simultaneously on a close real object and a close virtual object. We present a dynamic focus compensation approach to resolve VAC in which an electronically controlled dynamic lens is used to correct the focus of the virtual content. The dynamic lens is implemented using a pixel grid, enabling rapid lateral movement of the lens, thus increasing the lens quality and field of view.
