On-Air Character Recognition System For Visually Impaired People

摘要

Character recognition is a process which allows computers to recognize written or printed characters such as numbers or letters and to change them into a form that the computer can use. The character recognition system used to develop cost effective assistive technologies to provide blind people with greater degree of confidence in their activities. On-Air communication is developed by using the sensors which helps the blind people to recognize the character easily. The purpose of this paper is to take handwritten characters as input, process the character, train and test the character using machine learning method to recognize the pattern and character. Thus, it has been planned to design a device using sensors to recognize the characters written on air. The device is equipped with gyroscope and accelerometer to recognize the hand movement. While there is some on-air writing recognition system which uses wireless sensor- equipped pens. However, this project is planned for the use of visually impaired people to recognize the character.
