example 1

[0153] To provide better clarity, an example using representative values ​​is outlined below. The values ​​used below are for illustrative purposes only:

[0154] ·Assume IPD=72mm

[0155] ·Assume eye_proj_diff(x)=14mm

[0156] • Assume that the first of the two virtual objects is located 800 mm from the viewer in the virtual world, and set the virtual object to be directly in front of the viewer. Assume that the second of the two virtual objects is located 1600mm from the viewer in the virtual world and assume that the virtual object is directly in front of the viewer

[0157] • Assume l_screen_eye_distance = r_screen_eye_distance = 2400mm (distance from viewer to projection plane or screen)

[0158] In this case, the correct position of the center of the first virtual object projected onto the projection plane should be +72mm for the left eye (at Figure 8 shown schematically by 85 in , using a white ball to represent a virtual object), and -72mm for the right eye (at ...

Abstract

The present disclosure provides systems and methods to enable significant improvements in display systems utilizing projectors and a retro -reflective (RR) screen through use of transparent or semi-transparent RR material. An aspect of the present disclosure provides methods for optimization of optical properties of the RR material to achieve desired optical transparency parameters. Another aspectof the present disclosure provides methods for specific use cases for flexible, transparent and semi-transparent RR display systems.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit to U.S. Provisional Application Nos. 62 / 370,687, filed August 3, 2016, 62 / 370,690, filed August 3, 2016, and 62 / 380,313, filed August 26, 2016 , the entire content of said application is hereby incorporated by reference. Background technique [0003] State-of-the-art augmented reality (AR) and virtual reality (VR) systems that display stereoscopic or three-dimensional (3D) content typically require per-user physical calibration and physical adjustment of the head-mounted device (HMD) in order to Consider different interpupillary distances (IPD) and other size differences associated with each user. These adjustments are required because optical elements, such as lenses, may be located between the user's eyes and the display surface. Without physical alignment, the optics and display surface will not be in the proper position, which can lead to poor visual quality and a poor ...
