ABSTRACT In this project (HMI) Human Machine Interface has been studied extensively to control electromechanical rehabilitation aids using bios EEG, EOG, and EMG, etc. The various bios EOG signals have been studied in-depth due to the occurrence of a definite signal pattern. Persons suffering from extremely limited peripheral mobility like paraplegia or quadriplegia usually have the ability to coordinate eye movements. The current focus on the development of a prototype robotic hand controlled by EOG signals. EOG signals were used to generate control signals for the movement of the robotic arm. in this project we developed the EOG signal acquisition system. The acquired EOG signal was then processed to generate various control signals depending upon the duration and amplitude of the signal component. These control signals were then used to control the movements of the prototype robotic hand model. Introduction of Moving robotic hand with the help of EOG sign...
