COMMUNICATION AID FOR PARALYZED

ELECTRONICS AND COMMUNICATION ENGINEERING

Paralysis is defined as the complete loss of muscle function in any part of our body. The most important problem for patients suffered from paralysis is the lack of communication with other. A patient who is unable to communicate orally may experience elevated despair and thwarters, when his needs are not met due to failure of the care giver to grasp his needs. In the medical field, the problem of effective communication is heightened mainly in the Intensive Care Units, where patients are critically ill and tend to have barriers in communication such as muscular weaknesses that either result in preventing speech or making communication difficult or impossible. In our current scenario there exists many ways to communicate with paralyzed patients such as Chart based encoding and Brain computer Interface. But these are very complex and tiring and thus difficult for them to communicate. So we chose eye tracking system where we thought of developing a picture communication board that could illuminate the needs of the paralyzed patients through their eye gaze. Hence main aim of our project is to design real time system that can assist the paralyzed to specify the needs through their eye gaze. The image processing techniques is used to detect the eye gaze. By gazing at any one four frequent needs displayed on the communication board, the user can illuminate the needs notify the caretakers simultaneously by means of a buzzer and hence convey the needs effectively.
