Validation of a Gamified Eye-hand Coordination Tool for Post-stroke Upper Limb Assessment Using Tobii EyeX and Leap Motion: A Pilot Study

The HandEye system integrating Tobii EyeX and Leap Motion provides a low-cost, feasible approach for assessing visuomotor function in stroke rehabilitation settings. Strong associations with manual dexterity suggest potential as an adjunct assessment tool. However, limitations in study design, low training dosage, and unvalidated sensor accuracy necessitate larger randomized trials for clinical validation.
