Eye Blink Sensed Communication Media for Paralyzed Person Using Embedded System: Enhancing communication for paralyzed patients using eyeblink sensor

Abstract

Nowdays the paralyzed patients are facing lot of problems to inform their basic needs to others and the patient attendee also feel difficult to understand the requirements of the patient. This project solves the above problem. In this project eyeblink sensor and Microcontroller plays a major role. Eyeblink sensor senses the number of eyeblinks. It gives output depends upon number of blinks. The output of sensor is an analog value, which is not suitable for the microcontroller. So ADC (analog to digital converter) is used between sensor and microcontroller, which converts analog value into digital value. Microcontroller is programmed in such a way that to display the requirements in LCD unit and to control voice synthesizer. If the nurse is not in the ICU, information is sent to the Doctor’s room using Zigbee technology.
