psychological and physiological indicators, the effects on the body of
three-dimensional (3D) movies containing improper settings were evaluated
with 139 university students. The experiment consisted of two sessions: 1) a 3D
movie containing improper 3D settings was
compared with a 2D movie containing only the rightside images
presented to both eyes, and 2) the original 3D movie was compared with the same
3D movie altered to contain improper 3D settings. The results of this
experiment demonstrated clear deterioration of the subjective psychological
indicators (degree of motion sickness after watching the movies and comfort
level at 1-min intervals during the movie) with respect to the 3D movie
containing improper settings. On the other
hand, the physiological indicators (LF/HF ratio indicating the status of the
autonomic nervous system) changed as a result of watching a 3D movie, but were
unaffected by the presence or absence of improper 3D settings.
