Abstract: The present invention is a method and system for measuring human emotional response to visual stimulus, based on the person's facial expressions. Given a detected and tracked human face, it is accurately localized so that the facial features are correctly identified and localized. Face and facial features are localized using the geometrically specialized learning machines. Then the emotion-sensitive features, such as the shapes of the facial features or facial wrinkles, are extracted. The facial muscle actions are estimated using a learning machine trained on the emotion-sensitive features. The instantaneous facial muscle actions are projected to a point in affect space, using the relation between the facial muscle actions and the affective state (arousal, valence, and stance). The series of estimated emotional changes renders a trajectory in affect space, which is further analyzed in relation to the temporal changes in visual stimulus, to determine the response.

Abstract: The present invention relates to systems and methods for providing a push/pull perceptual learning technique to a subject demonstrating sensory eye dominance (SED) and/or amblyopia. More specifically, the weak eye of the subject is cued forcing it to become dominant, while visualization in the strong eye is suppressed over the course of a treatment regimen. Such systems and methods are shown herein to result in a perceptual learning and a reduction of interocular imbalance, as well as an improvement in the visual characteristics typically associated with very little or no SED and/or amblyopia, such as improved depth perception.

Abstract: There is disclosed apparatus and method for a test of eye dominance of human subjects for which on each 10-sec trial, one eye starts with a strong image that gets progressively weaker or does not get progressively stronger, while, at the same time, the other eye gets a weak image that gets progressively stronger. The initially strong image will always be seen at the beginning and eventually vision will flip to the other eye's view once that image has achieved sufficient strength to overcome the dominance of the initially strong stimulus (which itself is getting progressively weaker). The subject indicates recognition of the strengthening image and the time is recorded. Results show that the test provides a reliable measure of eye dominance which is seen to vary considerably among people within a sample of normal adults.
