Alcohol Impairment Detection in Healthy Adult Users With the Gaize Device

Completed

Conditions studied: Alcohol Impairment, Nystagmus, Virtual Reality, Lack of Smooth Pursuit, Impairment, Alcohol Intoxication, Intoxication

In brief

This study evaluates the effectiveness of the Gaize virtual reality headset as a non-invasive tool for detecting alcohol-related impairment through ophthalmic and neurological indicators. A total of 80 participants, evenly divided into an experimental (alcohol-consuming) and control (non-alcohol consuming) group, underwent baseline and post-consumption ocular assessments using the device. These assessments included: Lack of Smooth Pursuit, Horizontal Gaze Nystagmus at Maximum Deviation, Horizontal Gaze Nystagmus with Onset Prior to 45-Degrees, Vertical Gaze Nystagmus, Lack of Convergence, and Pupillary Rebound Dilation. The Gaize headset measured gaze vector and pupil size at 90 hertz per eye.

Having a prosthetic eye, blindness, or vision not corrected to normal.
Severe reactions or allergy to Alcohol. Participants with a history of severe adverse reactions to alcohol (e.g., allergies, intolerances, or medical conditions worsened by alcohol) are excluded.
Certain Medical Conditions: Participants with medical conditions or medications that could significantly affect cognitive and motor functions are excluded. A detailed list of such conditions and medications will be provided to potential participants during the screening process.
Pregnancy: Pregnant individuals will be excluded from the study due to the potential risks associated with alcohol consumption during pregnancy.
History of Severe Motion Sickness: Participants with a history of severe motion sickness in virtual reality environments may be excluded, as they may not tolerate the virtual reality headset well.
Individuals who have driven a vehicle (car, truck, bicycle, etc.) to the study location will not be eligible for participation.
