Intelligent System for Visually Impaired People Using Android

God gifted sense of vision to the human being is an important aspect of our life. But there are some unfortunate people who lack the ability of visualizing things. The visually impaired have to face many challenges in their daily life. The problem gets worse when they travel to an unfamiliar location. Visually impaired people use their senses like touch or sound for walking in a particular area, which is not possible for outdoor walking. Blind people are prone to sweep or knock whatever obstacle which pass before them during walking, subjecting them to risk of injury caused from fall. Our project aims to develop a smart stick for the visually impaired people. The smart stick will include a GPS/GSM system and obstacle detection mechanism. The GPS system is used by the user to know the current location and also to notify his friend or relative about the current location. The system is also comprise of LED lights for avoiding accidents during evening or night time and an ultrasonic sensor as input for detection of obstacles and Buzzer sound as the output for user. This could result in a better movement Of the user.
