The keeper's note
Polarization/wavelength-gated transparent display hardware (Smithwick, reissue).
Abstract
A transparent display system is provided where broadcast talent (or presenter) can see interactive content, tool palettes, prompts (and the like) as well as their own sketches and annotations, but a viewing audience sees only the broadcast talent and content intended for the viewing audience with the talent's annotation thereof. A transparent scattering screen together with optical filtering or gating of a first optical property of the light (e.g., polarization-based or wavelength-based) is used such that the first property of the light is projected onto the screen so the talent can see the projection, and a camera-side filter blocks the first property of the light so it is not seen by the camera. Simultaneously, a broadcast talent (or presenter) is illuminated by light having properties other than the first property, which allows the talent image to pass through the screen and the camera-side filter allowing the talent to be seen by camera. In some embodiments, a transparent “two-sided” display screen allows people on opposite sides of the screen to see each other, as well as independent 2D or 3D content from each person's side of the screen.
Background
.Iadd.CROSS-REFERENCE TO RELATED APPLICATIONS .Iaddend. (1) .Iadd.This application is a reissue of U.S. Pat. No. 10,924,639, which issued on Feb. 16, 2021, from U.S. application Ser. No. 16/424,932, filed on May 29, 2019..Iaddend. BACKGROUND (2) During sports analysis and talk-show television and video productions, the on-screen (or broadcast) talent needs to see and interact with video, pictures, and information on a shared screen with the viewing audience, but needs to have his/her face visible and make eye-contact with audience. Touch-screen monitors or green-screen backgrounds often have the information behind the broadcast talent and the talent facing away from the cameras and audience. Also, important content may be blocked by the talent and the audience may just see the back or profile of the talent. Furthermore, it is difficult for talent that is not familiar with green-screen technology to coordinate their actions with computer generated content displayed on off-screen monitors. (3) Accordingly, it would be desirable to have an optical display method and system that overcomes these issues and allows the broadcast talent to interact with the viewers and content more naturally in view of the aforementioned requirements and challenges.
Claims
1. A method for providing selectively viewable images on a transparent display screen having a first surface facing both a first side of the screen and a first .Iadd.in-person .Iaddend.viewer and having an opposite second surface facing both a second side of the screen and a second .Iadd.in-person .Iaddend.viewer, comprising: projecting a first projection image having light with a first optical property onto the first surface of the screen, such that light having the first optical property passes through the screen and is viewable by the second .Iadd.in-person .Iaddend.viewer viewing from the second side of the screen, and such that there is a first reflected light which reflects off the first surface of the screen; .[.and.]. blocking the first reflected light of the first projection image such that the first projection image is not viewable by the first .Iadd.in-person .Iaddend.viewer viewing from the first side of the screen; .[.and.]. passing at least a portion of an illuminated second viewer image of the second .Iadd.in-person .Iaddend.viewer having light with other than the first optical property through the screen such that the portion of the illuminated second viewer image is visible through the screen by the first .Iadd.in-person .Iaddend.viewer viewing from the first side of the screen.Iadd.; wherein the first optical property comprises at least one of polarization and wavelengths that make up the first projection image; projecting a second projection image having light with a second optical property onto the second surface of the screen, such that light having the second optical property passes through the screen and is viewable by the first in-person viewer viewing from the first side of the screen, and such that there is a second reflected light which reflects off the first surface of the screen; blocking the second reflected light of the second projection image such that the second projection image is not visible by the second in-person viewer viewing from the second side of the screen; passing at least a portion of an illuminated first viewer image of the first in-person viewer having light with other than the second optical property through the screen such that the portion of the illuminated first viewer image is visible through the screen by the second in-person viewer viewing from the second side of the screen; wherein the second optical property comprises at least one of polarization and wavelength that make up the second projection image; detecting motion of the second in-person viewer and providing an updated first projection image and updated second projection image in response to the motion of the second in-person viewer; and detecting motion of the first in-person viewer and providing an updated first projection image and updated second projection image in response to the motion of the first in-person viewer.Iaddend.. .[. ||
