Patent ID: 10966605

Abstract:
Methods and systems for assessing a health state of a person via eye movement-driven biometric systems are provided. Examples of the health states that it would be possible to detect with such a system are but not limited to brain injuries (e.g., concussions), dementia, Parkinson's disease, post-traumatic stress syndrome, schizophrenia, fatigue, cybersickness, autism, Bipolar Disorder and other health conditions that manifest themselves in abnormal behavior of the human visual system. Described methods and systems can also detect influence of alcohol and/or drugs. The system extracts biometric template of a person by deriving features from the captured eye movement signal. The system may compare the difference between previous healthy state of a tested person and newly captured template or an averaged biometric template created from the records of multiple healthy people state of multiple people and a newly captured template from a person who needs to be tested. Based on the difference between the templates, a decision of a health state of a person is made. Described methods and systems may work on any device that has eye tracking capabilities including but not limited to desktop mounted eye tracking systems, head mounted eye tracking systems such as Virtual Reality and Augmented Reality or stand-alone mounted eye tracking systems.
