Vision, Gifted by god to human being for sense, we can see the beauty of nature with the help of our eyes, things that happen in everyday life. But some unfortunate people lack that ability to experience these things. During their day-to-day tasks they face several issues. The person with visual impairment will rely on senses other than sight, such as hearing and feeling of touch to guide him. To minimize the difficulties faced by blind humans, a project has been designed, which will give direction to Visually Impaired people to reach their destination. The agenda of this project is to provide the self-assistance for the visually impaired persons. If in case the user fall in a critical position, the sensors connected with microcontroller will senses the situation. We implemented a wrist mounted system (Gauntlet) for visually impaired users which allows them to detect and avoid obstacles and allows the user to point the device in any direction. [1] This system is depend on an ultrasound sensors which can read data, when objects detected in the environment by estimating of the ultrasound signal, the device detect obstacles and determine which directions should be avoided by giving a tactile feedback using servomotors. This system also consists of a Braille keypad with a panic button which when pressed sends the message of his current GPS coordinates to their Family person and also there are two buttons in the keypad which when pressed speaks the time and date for the user. Additionally we have a device control which will be operated by using Braille keypad, the device control section of the microcontroller is connected with devices as per our need devices may be lights, fans, and can also be used to lock and unlock the door, and for this we are using the GSM (Global System for Mobile Communications) module.
