ASTITVA: Assistive Special Tools and Technologies for Inclusion of Visually Challenged

Visually handicapped persons face inconvenience in walking around new places freely and are prone to accidents due to lack of eyesight. To make their lives trouble free this paper proposes the prototypes of two specially designed devices. First is a smart walking stick based on the TLC (Traffic Light Crossing Algorithm) which effectively allows them to dodge obstacles and cross traffic signals. Second proposed device, is a smart helmet that warns the vehicles whenever the person walking ahead of them, takes a turn or stops moving by blinking LEDs. It also vibrates to warn if there is a vehicle or person close behind the user. These features are achieved using ultrasonic sensor and accelerometer module. This device ensures a safe travel in the day as well as in the night Together these two devices when put into practical utilisation, can transform the lives of the disabled people in our society.
