How visual discomfort changes with horizontal viewing angle on stereoscopic display
When viewing stereoscopic displays, people may not always be able to stay
exactly in front of the display. It is known that viewing stereoscopic display
from different vertical angles lead to different visual discomfort. However,
the effects of horizontal viewing angle on stereoscopic visual discomfort have
been rarely investigated, especially for household stereoscopic displays. In
this study, subjects were required to view a stereoscopic display from various
horizontal viewing angles, and assessed their visual discomfort during viewing.
The visual stimuli have various amount of disparities: positive disparity,
negative disparity or zero disparity. Results showed that the visual discomfort
changes with horizontal viewing angle, and greater angles generally lead to
more serious visual discomfort. Furthermore, the relationship between visual
discomfort and horizontal viewing angle can be approximately expressed by a
quadratic function
