We have been conducting research focusing on the human gaze as a principal biological reaction while viewing videos. In this paper, we clarify the difference in the area of gaze region under different sound conditions; monaural (1.0 ch), stereo (2.0 ch), and surround (5.1 ch). We measured the gaze of subjects viewing video scenes of natural landscapes and calculated the horizontal and vertical standard deviations of the gaze points and the area of gaze region defined from them. A two-way analysis of variance shows the main effects of each of the sound and scene conditions on the vertical standard deviation of the gaze points and the interaction effect and the main effect of the sound condition on the area of gaze region. In addition, a multiple comparison test shows the significant differences in the vertical standard deviation for the interaction effect between the sound and scene conditions and in the area of gaze region for the sound conditions between monaural and stereo or surround. The hypothesis that the variance of gaze points is expanded by the surround sound is confirmed experimentally.
