One of the primary neural disorders is Paralysis, which causes loss of motion in one or more parts of the body muscles. Quadriplegia is a condition, where both the arms and the legs are paralyzed; as a result, the person is entirely dependent on the caretakers. To help them overcome their difficulties, we proposed a system which can control the house appliances, to communicate, monitor and alert the caregivers or the doctors in the case of an emergency by using his/her eye movements. These eye movements can be recorded using Electrooculography (EOG) that can be used to perform these simple tasks. EOG is the measurement of the corneo-retinal standing potential of the eye. This paper describes how the acquisition of EOG signals is made which can be used to control the home appliances. Also, a communication method for the quadriplegic patients to interact with the caregivers and the designing of a monitoring system which can be used for monitoring the quadriplegic patients and an alarm with pop-up message that can be used to alert the caretakers. The proposed work also describes the electrode placements so as to reduce the artifacts, the types of electrodes used, simple circuits and the programming that are used to control the house appliances using EOG signals. The picked up EOG signal from the subject is given to the processing block which suitably provides an output which can be utilized as an input to the NI MyRIO where the programming is done to control the household appliances and for communication.
