Abstract
People coordinate their eyes and head during typical activities of daily life. Subjects with poor head-eye coordination find it difficult to make eye contact with others, limiting their social interaction. Inspired by the natural vestibulo-ocular reflex (VOR) during head-eye coordination, we propose a gaze control interface to drive a robotic neck brace. This system will enable those with poor head control to perform head movements using their eyes. The control interface of this system is triggered by the user's pupil motion in a virtual field of view (FOV) to produce head movements. The results indicate that the control interface is capable of rotating the head towards the target within 5° of difference of the desired head angle. This study shows that the proposed bio-inspired control promotes natural eye-head coordination, which may be potentially useful for individuals with poor or limited neck control. © 2020 IEEE.
