Embodiment Construction

[0022] Embodiments relate to image display systems and methods for display system calibration. Spatial computing overlays digital world content on real world content in a spatially interactive manner by combining digital light fields, sensing, and computing. The digital content rendered by spatial computing technology preferably works in tandem with the real world environment and more importantly with the human eye-brain system, which is the ultimate judge of the system's success. Therefore, to develop such spatial computing systems, it is necessary to have an agent of the human eye-brain system to calibrate and verify the performance of spatial computing systems.

[0023] Embodiments provide a camera design that mimics human physiology (eg, the human eye) in at least one or more of: geometry, optical performance, and / or motion. Specifically, embodiments provide a camera (eg, an eyeball camera) that not only employs the same corneal and pupil geometry as the human eye, but al...

Abstract

Embodiments provide camera designs (e.g., eyeball cameras) that mimic the human eye in terms of geometry, optical performance, and / or motion. The eyeball camera employs the same cornea and pupil geometry as the human eye and has an iris and pupil configured with multiple texture, color, or diameter options. The resolution of the eyeball camera is designed to match the sensitivity of typical 20 / 20 human vision, and the focal length is adjusted from 0 to 4 diopters. A pair of eyeball cameras are independently mounted on the two hexapod frames to simulate gaze and convergence of human eyes. Perceptual virtual and real worlds are calibrated and evaluated based on eye conditions such as pupil position and gaze using an eyeball camera. The eyeball camera acts as a bridge, combining data from spatial calculations (such as eye tracking, 3D geometry of the digital world, display color accuracy / uniformity, and display optical quality (clarity, contrast, etc.

Description

[0001] Cross References to Related Applications [0002] This application is a non-provisional application of, and claims the benefit of, U.S. Patent Application No. 62 / 873,641, filed July 12, 2019, entitled "EYEBALL CAMERA SYSTEM AND METHODS FORDISPLAY SYSTEM CALIBRATION," which is adopted in its entirety for all purposes Incorporated herein by reference. Background technique [0003] Modern computing and display technologies have facilitated the development of systems for so-called "virtual reality" or "augmented reality" experiences, in which digitally produced images, or parts thereof, are presented to the user. Virtual reality or "VR" scenarios typically involve the presentation of digital or virtual image information, but are opaque to otherwise actual, real-world visual input; augmented reality or "AR" scenarios typically involve the presentation of digital or virtual image information as a visual representation of the user's surroundings. Enhanced visualization of th...
