Abstract

The presentation shows how dynamic aberrations correction can increase the apparent resolution, eliminate color fringing and pupil swim effects, and enlarge the eye-box in the highest-end displays, such as Varjo VR-1 and HP Reverb G2.Having to achieve high resolution, wide field of view, and large eye-box, the VR/AR head-mounted display makers face the challenges impossible to overcome by hardware design alone. Even the latest-and-greatest devices retain the common flaws spoiling user experience: blur and color fringing outside of the small “sweet spot,” picture quality degradation and geometry distortion at wide gaze angles, and a tiny eye box. In order to achieve realistic picture quality and natural visual experience, the rendering pipeline has to include advanced image pre-processing beyond the standard geometry warp and channel scaling. Almalence created the Digital Lens, a computational solution utilizing a precise characterization of HMD optical properties along with a dynamic aberration correction technique, adjusting on the fly to the eye-tracking data.
