EOG Based HMI For Paralysed People To Control Electrical Devices

Abstract

Bio-based human machine interface (HMI) has attracted more and more attention of researchers all over the world in the recent years. In this paper, a HMI system based on electro-oculogram (EOG) is proposed. It transforms electric potentials recorded by horizontal and vertical EOG into computer/pattern re-organization module wirelessly, in order to control external equipment according to eye movements. The objective is to design a HMI to control electrical devices using EOG signals. The HMI output is used to move the cursor on the graphic display which has several buttons and each button on clicking by blinking of eyes activated corresponding electrical devices. The RF interface between acquisition and processing part and application so that is easy to handle and easy to install in homes and hospitals
