EOG Based Interface to Command a Powered Orthosis for Lower Limbs

Abstract

Users of powered or thoses for lower limbs, use Human Machine Interface (HMI) to trigger these devices. This work, presents a HMI based on Electrooculography (EOG) to command a powered orthosis for lower limbs, through the eye movements. This interface, is responsible by generation of high-level commands like: walking, stop, sit down, stand up, up and down stairs. By using this HMI, the user's hand will always be free to perform other tasks. Preliminary results, showed that, it was possible to command a powered hip-knee-ankle-foot orthosis through eyes movements.
