Visual Discomfort Estimation for Stereoscopic 3D Contents

Stereoscopic 3D displays are widely applied for home entertainments. However, some viewers complain uncomfortable 3D perception when they watch 3D contents. For generating comfort stereoscopic 3D contents, we proposed three qualitative models for measuring the discomfort. Three experiments for 1) limitation of the viewing angle 2) variance of the viewing angle for the whole scene 3) variance of the viewing angle inside an object are designed for generating the models in this paper. On the basis of the experiments, we find three simple features in terms of thresholds for estimating the potential visual discomfort for a given stereoscopic 3D content. We believe these thresholds can be applied for the production of comfort 3D contents, especially for automatic or semi-automatic generation of 3D contents.
