Abstract
The present disclosure relates generally to a system and method for detecting or indicating a state of impairment of a test subject or user due to drugs or alcohol, and more particularly to a method, system and application or software program configured to creating a virtual-reality (“VR”) environment that implements drug and alcohol impairment tests, and which utilizes eye tracking technology to detect or indicate impairment.
Claims20
A system configured to implement one or more tests indicative of impairment due to drugs or alcohol, the system comprising:
- a VR headset configured to display at least one virtual environment and at least one virtual object in the environment;
- an eye tracking component;
- and
- a processor in communication with a memory comprising instructions to measure a change in one or more features of a test subject's eyes with the eye tracking component,
- wherein the change in one or more features of the test subject's eyes is induced by a manipulation of the at least one virtual environment or the at least one virtual object displayed by the VR headset, and
- wherein the memory further comprises a comparison component having instructions to output drug classification identification results with a probability or percent match associated with at least one drug class.
A method of indicating impairment due to drugs or alcohol, the method comprising:
- displaying at least one virtual environment and at least one virtual object in the environment with a VR headset, wherein the VR headset includes an eye tracking component and a processor in communication with a memory, the memory including instructions for measuring a change in one or more features of a test subject's eyes with the eye tracking component;
- manipulating the at least one virtual environment or the at least one virtual object displayed by the VR headset;
- measuring parameter values representative of the change in one or more features of the test subject's eyes after manipulating the virtual environment or the virtual object;
- and
- correlating the measured parameter values with predetermined baseline standards of impairment;
- and,
- predicting a level of impairment based on the correlation with the predetermined baseline standards of impairment and outputting the prediction;
- determining drug classification identification results with a probability or percent match associated with at least one drug class;
- and,
- outputting the correlation with the predetermined baseline standards of impairment.
A method of operating a VR headset to indicate a level of impairment due to drugs or alcohol, the method comprising:
- initiating one or more software components configured to perform one or more tests with the VR headset which indicate impairment due to drugs or alcohol;
- running the selected test according to instructions provided by the one or more software components;
- activating an eye tracking hardware component to begin recording raw eye tracking data and conditions of at least one virtual tracking object and at least one virtual environment generated by the VR headset;
- and saving and outputting data generated after running the selected test, and wherein the data outputted after running the selected test includes drug classification identification results with a probability or percent match associated with at least one drug class.
