He has made significant contributions to the field of optical technologies, particularly in the development of head-mounted displays. With a total of four patents to his name, Lewis continues to push the boundaries of innovation in this area.

Latest Patents

Lewis's latest patents include "Dynamic distortion correction for optical compensation" and "Pupil swim corrected lens for head mounted display." The first patent describes a distortion calibration system that generates a distortion map for a head-mounted display (HMD). This system utilizes a camera to capture images of a test pattern displayed by the HMD from various positions and states. The captured images are then used to determine a distortion map, which is uploaded to the HMD as part of an optical model. The HMD features an electronic display, an eye tracking unit, an optics block, and a module that estimates distortion values based on eye tracking information. The module adjusts the state of the HMD to optimize the viewing experience.

The second patent focuses on a lens designed for head-mounted displays, which directs and collimates image light from the electronic display to the user's eye. This innovation aims to reduce the pupil swim effect by configuring the lens to minimize differences in observed distortions at various gaze angles.
