DESIGN AND DEVELOPMENT OF EMG SIGNAL BASED SYSTEM FOR PARALYZED PEOPLE

In recent years, physically disabled person faces more limitation in day to-day communication. There is a demand in today’s world for the development of a support system to physically disable people/paralyzed person. In this work, an EMG based control system for eye movement is proposed. Patients distressing from facial paralysis are on the risk of defacement and defeat of visualization due to failure of blink function.

Eye movements tracking is helpful for disabled people suffering from Amyotrophic Lateral Sclerosis. In this research work, an EMG based eye control system for a paralyzed person is proposed. Trapezium EMG signals are acquired, analyzed and then processed into a controlled movements (left, right, up and down) using an embedded circuits. The system allows the patient to choose a smooth independent movement in the control state or non-control state. The movements depend upon the strength of the EMG signals acquired.
