Google received 1 granted patent in VR & AR.
The patent addresses calibration challenges in augmented and mixed reality headsets when prescription lenses are incorporated into the optical system. The technology corrects both image alignment and color accuracy to ensure proper display performance with integrated prescription optics.
Google's single VR & AR patent tackles a testing challenge that arises when prescription lenses become part of an AR or MR headset's optical path. The patent describes a calibration method that accounts for how prescription corrective elements interact with the display's lightguide system. This approach aims to compensate for the optical effects introduced by prescription lenses, ensuring that images remain properly aligned and free from distortion when viewed through both the headset's display optics and the user's prescription correction.
