Dual-Path Optical Measurement System with Integrated Pupil and FOV Scanning
This technology is a compact optical measurement system designed to test and evaluate head-mounted displays used in augmented, virtual, and mixed reality. The system captures both wide field-of-view images and fine image detail at the same time by splitting light into two coordinated measurement paths. A shared entrance pupil and integrated scanning...

Dynamically Foveated Head-Mounted Displays with High Resolution Inset Image Based on Micro Lens Array
This technology is a head-mounted display architecture that provides high visual detail where the eye is looking, while maintaining a wide field of view for peripheral awareness. By using optical image duplication and selection to shift the high-resolution region across the display area as viewing direction changes, the system creates a small, high-resolution...

Dynamically Controlled Pupil Steering Method for Enhanced Light Efficiency in Head-Mounted Displays
This is a programmable backlight display for head-mounted displays (HMDs) that dynamically steers light to the viewer’s pupil based on real-time eye tracking. This method reduces power consumption by illuminating only the necessary region corresponding to the pupil location while also improving brightness uniformity and efficiency. It also helps...

Perceptual-Driven Foveated Optical See-Through Head-Mounted Displays
This invention consists of the design and embodiments of a statically optical see through head-mounted displays (OST-HMDs) in which the angular pixel density decreases with the increase of the filed eccentricity according to a specified angular pixel density function. To facilitate the head-mounted display capability to simultaneously see the image...

Frontal Face Sythesis from Multiple Low-resolution Images
INV-20067 Background Face-based generative tasks (e.g., face rotation, hallucination, and attribute editing) have gained more traction in research communities with advancements in deep learning. However, the practical significance of identity-preservation is frequently overlooked, which generates significant challenges for face images with large...
