“Invisible” Layer for Lampix

My proposal is adding “invisible” play function to Lampix. There will be another projector with an unpolarized filter projecting different information on top of the first projection. The information from the second projection can only be seen by the main users who wear glasses with polarized lenses on them. The main users can choose to only display part of information with visible light or hide all the information.

This technology could be very useful in many situations like in presentation, only the speaker could see the scripts and other supportive information. Or our user could secretly get more information during the negotiation which is a great advantage.
