This dual-screen system allows presenters to show two sources at one time. In a distance learning auditorium like this one, far site video can be shown on one screen while a PC or other source is displayed on the other.
The rear-facing light fixtures are designed to illuminate audience members when they interact with the far site. These shine on the front of the participant like studio lighting. This eliminates facial shadows that are a typical result of down-facing, overhead lights. Studio lights also illuminate the presenter and, optionally, different parts of the stage.
