Patent

CA 2657762

Alteration of a fixation or peripheral stimulus displayed on a computer-driven display allows a human subject to maintain extended visual fixation upon the resulting dynamic stimulus. The fixation is presented upon the display and the stimulus is altered to allow resensitization of the subject's retina, thereby allowing prolonged visual fixation upon the resulting dynamic target. A dynamic stimulus may utilize a frequency doubling illusion.

La détérioration d'un stimulus de fixation ou périphérique affiché sur un écran commandé par ordinateur permet à un sujet humain de conserver une fixation visuelle étendue lors du stimulus dynamique résultant. La fixation est présentée à l'écran et le stimulus est altéré pour permettre une resensibilisation de la rétine du sujet, permettant ainsi une fixation visuelle prolongée lors de la cible dynamique résultante. Un stimulus dynamique peut utiliser une illusion de fréquence doublée.
