  • Patent number: 3970374
    Abstract: An optical visual communication system especially adapted for a classroom setting. A plurality of first plane mirrors are oriented over a plurality of student desks in a classroom. A second plane mirror is oriented in the visual field of an instructor or teacher. The first plane mirrors reflect images from their respective student desks to the second plane mirror which in turn reflects these visual images to the eye of an instructor. Since there are two reflections between the students' desks and the eye of the teacher, the visual images are not reversed. Various embodiments of mounting means for mounting the first plane mirrors are disclosed, including flexible arms and clamps secured to a grid network carried by and suspended from the ceiling of a classroom. One embodiment also shows the use of magnifying elements.
