Eye-Movement-Controlled Wheelchair Based on EOG for People with Quadriplegia

Abstract

The number of disabled people is increasing at a rapid rate, disability to control limbs due to accidents and wars are the major cause of immobility. Immobility hinders daily activities and leads to social restrictions which isolate them from the rest. Forfeiture of the ability of quadriplegic people to control their hands isa serious challenge in designing wheelchairs that meet their needs. The aim of this project is to invest the eyes and tongue movements of quadriplegic people to design a motorized wheel chair controlling system capable of receiving the digital output from an electrooculographic amplifier and filter, to analyze these electrooculograms (EOGs) electronically for controlling wheel chair movements, and pressure sensor, to enable these people control the activation and deactivation of the eye-controlling-system. For more accuracy, the flexiForce sensor mounted on the cheek recipes pushes from the tongue, it is used to ON/OFF eye-controllingsystem, which helps the patient to look freely when he/she don’t need it and just want to walk straight .
