Abstract: A method of discovering relationships between eye physiology and cognitive and/or emotional responses of a user starts with engaging the user in a plurality of tasks configured to elicit a predicted specific cognitive and/or emotional response. A first camera films at least one eye of the user recording a time series of events of eye movements of the user, the camera not being in physical contact with the user. The first time series of eye movements are sent to a computing device which compares the eye movements and the plurality of events. The computing device can then identify at least one relationship between eye movements that correlate to an actual specific cognitive and/or emotional response.
