Optical Mapping Near-eye Three-dimensional Display with Correct Focus Cues
This addresses eye fatigue and discomfort in wearable devices for users of virtual or augmented reality.
The authors tackled the vergence-accommodation conflict in near-eye 3D displays by developing an optical mapping method that creates multiplane volumetric images with correct focus cues, resulting in a system that drives eye accommodation consistently with stereopsis and offers advantages in adaptability, image dynamic range, and refresh rate.
We present an optical mapping near-eye (OMNI) three-dimensional display method for wearable devices. By dividing a display screen into different sub-panels and optically mapping them to various depths, we create a multiplane volumetric image with correct focus cues for depth perception. The resultant system can drive the eye's accommodation to the distance that is consistent with binocular stereopsis, thereby alleviating the vergence-accommodation conflict, the primary cause for eye fatigue and discomfort. Compared with the previous methods, the OMNI display offers prominent advantages in adaptability, image dynamic range, and refresh rate.
