摘要：

As there is no currently available portable, visuomotor assessment of concussion at the sidelines, we present preliminary development of an approach based on Predictive Visual Tracking (PVT) suitable for the sidelines. Previous work has shown PVT sensitivity and specificity of 0.85 and 0.73, respectively, for standard deviation of radial error for normal and acute concussion (mild Traumatic Brain Injury, or mTBI), using a simple orbiting target stimulus. We propose new variants of the radial and tangential error metrics and conduct preliminary evaluation in Virtual Reality when applied to two different target motions (orbit and pendulum). Our new local visualization is intuitive, especially when considering evaluation of the pendulum target. Initial results indicate promise for baseline-related, personalized concussion testing in extended reality.
