Abstract:
1. A method of identifying a motion-sickness problem in an image sequence, comprising: providing a head-mounted display having a switchable viewing area that switches between a transparent and an opaque state; using a processor to analyze the image-sequence information to identify a propensity that the image-sequence can induce motion sickness in a user and forming a saliency map calculated from salient static and dynamic visual features in the image sequence information, wherein the static and dynamic visual features are moving and static objects; identifying moving and static objects and parameters in the saliency map describing the characteristics of the moving and static objects and the distribution of salient static and dynamic visual features in the saliency map that can induce motion sickness; determining the propensity of the identified moving and static objects and parameters in the saliency map to induce motion sickness; producing a signal based upon the determined propensity to induce motion-sickness; and modifying the transparency of the switchable viewing area in response to the signal.
