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.

A cushion, using magnetic friction as base protection is specifically tested and designed for use in helmets to minimize the risk of concussions. The cushion can be used in a two layer helmet where the magnets are used to repel the impact normally taken straight to the head. The magnets can be placed in between the layers to not only take the impact, but also give that force back towards the source, creating a cushion like no other helmet. With this two-layer system, one can measure that the first layer of magnets takes the hit and uses the second layer to push back off of. This movement that the helmet takes significantly improves protection of the brain as compared to conventional helmets.

Methods and materials are disclosed for evaluating head brain injuries that do not involve blood loss or skull fractures, such as possible concussions. These methods and materials involve bioreagents (such as monoclonal antibodies, single-stranded DNA or RNA, etc.) affixed to computer-readable devices handled by electronic readers that can interact with portable computers (such as laptops, pads or tablets, smart phones, etc.). The bioreagents will detect the presence and concentration of at least two metabolites that are released by mitochondria in response to cellular damage. Additional bioreagents may be included, for detecting and quantifying other damage-associated molecular patterns (DAMP's). When used along with cognitive, reasoning, and / or response tests, this type of analysis can help non-physicians assess the severity of, and proper responses to, head traumas that otherwise are difficult or impossible to reliably evaluate.

Embodiments relate to a system for generating simulated eye movements and eye responses related to concussion symptoms for training medical practitioners. The system includes a computer device with a display that displays the pair of simulated eyes. Scenarios are generated and executed, in which simulated eye movements and responses to external stimuli are representative of typical symptoms associated with having a concussion. A user (e.g., medical trainee or medical trainer) provides external inputs e.g., voice commands, stylus movements, etc.) and assess eye movements provided by the scenarios and eye responses to the external inputs.
