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.
