INTRODUCTION
This project is primarily dedicated to all those persons who are handicapped by any means. THE MOST IMPORTANT POINT ABOUT THIS DEVICE IS THAT, IT CAN BE EMPLOYED FOR THOSE PERSONS WHO ARE NOT ABLE TO MOVE, SPEAK EVEN UNABLE TO DO ANYTHING. THERE IS A SENSOR WHICH IS CAPABLE OF SENSING ANY TYPE OF TILTING OF ITS OWN. THIS IS KNOWN AS ACCELEROMETER. WE CAN MOUNT THIS SENSOR TO ANY PART OF THE BODY OF THE HANDICAPPED PERSON. AS THE PERSON TILTS HIS PART OF THE BODY ON WHICH SENSOR IS MOUNTED, WE CAN SENSE THE MOTIVE OF THAT PERSON ACCORDING TO THE TILTING. ONCE THE PERSON IS TRAINED FOR ITS OPERATION, HE CAN SAY ANYTHING WHATEVER HE WANTS TO. The data from accelerometer is transmitted wirelessly to the microcontroller. The microcontroller keeps on sensing the change in data, whenever there is any change in the status of the accelerometer, its data is sensed by the microcontroller. There is an LCD to display the data i.e. predefined messages stored for the user. Also the buzzer beeps so that any person will come to know about the message. This is very cost effective and easy operated device. The advantages of the device need no explanations as it can be very helpful for patients who because of illness cannot speak and can only move their fingers to communicate.
