EOG Based Interface to Command a Powered Orthosis for Lower Limbs

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.
