Abstract:
1. A method to determine the propensity of an image-sequence to induce motion sickness in a viewer, comprising: using a processor to analyze the image-sequence information to extract salient static and dynamic visual features in the image sequence information, wherein the visual features represent objects; using the processor to form a saliency map from the extracted salient static and dynamic objects; evaluating distribution of the salient static and dynamic objects in the saliency map to estimate a probability of the image sequence causing the viewer to make eye and head movements, wherein the distribution evaluation includes evaluating the distance between pair-wise salient locations in the saliency map, evaluating the number of salient locations on the periphery of the map compared to the number of salient locations in the center of the map, evaluating the amplitude of a salient location, or evaluating the number of highly salient locations in the saliency map; and using the estimated probability to determine the propensity that the image-sequence would induce motion sickness in a user as a consequence of the eye and head movements.
