Smart cane for visually impaired based on IOT

Abstract

There are numerous issues over which people have no control visual deficiency is one of such issues. It grabs the striking visual magnificence of the world from a person's life. Be that as it may, missing the excellence of nature gets one of the last concerns of such individuals as they need to confront various challenges to perform even the most nuts and bolts of undertakings in their everyday life. One of their most prevailing issues is of transport, like going across streets, going in trains, or other public spots. They always require human assistance to do so. But sometimes they are rendered helpless when no such assistance is offered. Their dependencies deteriorate their confidence. Traditionally they have been using the conventional cane stick to guide themselves by touching/poking obstacles in their way. This causes a lot of accidents and hence is dangerous for them and others. As this is a technologically driven era we decided to aid these differently abled people by coming up with a technology utilizing solution. We call it the “Smart Stick”. It is a device which guides the user by sensing obstacles in the range of stick. It will identify all obstacles in the path with the help of various sensors installed in it. The microcontroller will retrieve data and pass it on as vibrations which will notify the user about hurdles on the way. It is an efficient device and will prove to be a big boon for blind people. The proposed conceptual framework demonstrates an excellent generalization performance and accurate results which mean that the prototype has the capability to fulfill object detection, location identification and obstacle avoidance tasks efficiently in uncertainty environments.
