Survey on Obstacle Detection and its Notification through an Android App for Visually Impaired People
Abstract
Assistive technology is an emerging research area, where adaptable devices can be developed to help older people to achieve independence in their daily activities. Ultrasonic sensors attached on the device used will generate the data about the obstacle it detects and will notify the user through an android application. The visually impaired as well as a person having impaired hearing can use the proposed wearable device which will help to improve his mobility and make it hassle free.
