AI Technical Summary

Problems solved by technology

Correct retinal focus cues require very high angular density light fields, making building a sufficiently accurate 3D display capable of emitting the necessary light a challenge
Furthermore, the rendering of artificial images may often need to be performed with sufficiently high fidelity

Embodiment Construction

[0098] According to some embodiments described herein, a wireless transmit / receive unit (WTRU) may, for example, function as a light field display, and / or may include a light field display.

[0099] Figure 1A is a diagram illustrating an exemplary communication system 100 in which one or more disclosed embodiments may be implemented. Communication system 100 may be a multiple-access system that provides content (such as voice, data, video, messaging, broadcast, etc.) to multiple wireless users. Communication system 100 may enable multiple wireless users to access such content by sharing system resources, including wireless bandwidth. For example, communication system 100 may employ one or more channel access methods such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal FDMA (OFDMA), Single Carrier FDMA (SC-FDMA), zero-tail unique word DFT-extended OFDM (ZT UW DTS-s OFDM), unique word OFDM (UW...

Abstract

An apparatus and method are provided, some embodiments of the apparatus may include a tracking module configured to track viewer movement adjustments; and a light field image display structure configured to display a light field image using the viewer movement adjustment. Some embodiments of the method may include projecting a beam spot on a viewer of a light field display; determining an estimated position of a beam spot reflected from the viewer; detecting an actual position of a beam spot reflected from the viewer; and determining an image correction parameter based on a comparison of the estimated position and the actual position of the beam spot reflected from the viewer.

Description

[0001] Cross References to Related Applications [0002] This application is entitled "Method and System for Continuous Calibration of a 3D Display Based on BeamSteering (Method and System for Continuous Calibration of a 3D Display Based on BeamSteering")" and filed on July 1, 2019 Non-provisional filing of patent application Serial No. 62 / 869,478 and claiming the benefit of that patent application under 35 U.S.C. §119(e), which is hereby incorporated by reference in its entirety. Background technique [0003] The human brain perceives and determines the depth of an object being viewed in part by receiving signals from the muscles used to orient each eye. This eye convergence uses a simple triangulation method to estimate object distances. The brain correlates the relative angular orientation of the eyes with the determined depth of focus. Eye muscles attached to a single eye lens automatically adjust the lens shape in such a way that the eye is focused to the same distance ...
