Objective characterization of treatment-phase oculomotor behavior

Determine whether oculomotor behavior can objectively characterize drivers undergoing treatment for stimulant abuse, with the aim of improving detection of treatment-related driving risk through in-vehicle monitoring.

Background

The paper emphasizes that most prior research has examined acute stimulant intoxication rather than drivers in withdrawal or active treatment. It investigates whether eye-tracking and biomechanical measurements can distinguish drivers undergoing methamphetamine rehabilitation from healthy controls, using a driving simulator and a K-nearest-neighbors classifier.

The unresolved issue is whether oculomotor behavior provides an objective and reliable characterization of drivers undergoing treatment for stimulant abuse. Although the study reports differentiating patterns in pupil angular velocity and visual fixation, its small sample and low-fidelity simulator limit the broader generalization of these findings.
