Smart Assistive Navigation Devices for Visually Impaired People

This paper is based on the design of a smart assistive device to help visually impaired people. Visually impaired people have been facing a lot of hardship in their day to day life. Navigating from one place to another is a toilsome task for them and the conventional blind walking stick has its own drawbacks or limitations. It is not of much assistance to these people of our society. Our research is motivated by the inability of the physically disabled people in their ambulation and we took an attempt to make their routine life painless and trouble-free. We designed two devices which can be of immense utility to the sightless people. We designed a smart glass and a smart pair of shoes by integrating various sensors with raspberry pi. The paper presents the functionalities and the working principle of the smart glasses and shoes and the varieties of tasks they are capable of accomplishing. The novelty of our work lies in processing data from both the devices and provide a better solution for navigating and day to day activities.
