Analysis of the viewing zone of multiview autostereoscopic displays

The viewing zone of a multi-view autostereoscopic display can be shown to be completely determined by four parameters: the width of the screen, the optimal distance of the viewer from the screen, the width over which an image can be seen across the whole screen at this optimal distance (the eye box width), and the number of views. A multi-view display's viewing zone can thus be completely described without reference to the internal implementation of the device. These results can be used to determine what can be seen from any position in front of the display. This paper presents a summary of the equations derived in an earlier paper. These equations allow us to analyze an autostereoscopic display, as specified by the above parameters. We build on this work by using the derived equations to analyze the configurations of the extant models of the Cambridge autostereoscopic display: 10' 8- and 16-view, 25' 28-view, 50' 15-view displays and an experimental 25' 7-view display.
