System and method for determining human emotion by analyzing eye properties
First Claim
1. A computer implemented method for detecting human emotion in response to presentation of one or more stimuli, based on at least measured physiological data, the method comprising:
- presenting at least one stimulus to a subject;
collecting data including physiological data from the subject, the physiological data including pupil data, blink data, and gaze data;
performing eye feature extraction processing to determine eye features of interest from the collected physiological data; and
analyzing the eye features of interest to identify one or more emotional components of a subject'"'"'s emotional response to the at least one stimulus.

Abstract
The invention relates to a system and method for determining human emotion by analyzing a combination of eye properties of a user including, for example, pupil size, blink properties, eye position (or gaze) properties, or other properties. The system and method may be configured to measure the emotional impact of various stimuli presented to users by analyzing, among other data, the eye properties of the users while perceiving the stimuli. Measured eye properties may be used to distinguish between positive emotional responses (e.g., pleasant or “like”), neutral emotional responses, and negative emotional responses (e.g., unpleasant or “dislike”), as well as to determine the intensity of emotional responses.
