Abstract: A screen segment, viewing isolation apparatus is provided for a video screen that is divided up into plural screen segments and includes a housing which includes a plurality of optical channels, wherein each of the optical channels is registrable with a respective screen segment. When a video screen is divided into four screen segments, four players can employ an embodiment of the invention to see their respective screen segments without being confused by screen segments of other players. An embodiment of the invention that accommodates four players can be converted into an embodiment which accommodates two players for separately viewing two screen segments. The housing includes a top housing wall, a bottom housing wall, and exterior wall supports connected between the top housing wall and the bottom housing wall. An interior vertical partition is connected between the top housing wall and the bottom housing wall at medial positions of the top housing wall and the bottom housing wall.
