Navigation System for Blind Using QR Code

Eyes is the main organ of the visual system, it gets images seen by the person and turns them into an electrical signal which is carried along the optic nerve to the brain. Once the signal reaches the visual cortex, it is “translated” by the brain, to create the image so the person can interpret the environment. But for some people they can’t able to visualize the image by seeing only, for that they need to touch. Nowadays technology advancement is trying to improve life of such visually impaired people. In this research, we propose a mobile based application that identifies object using Smartphone camera by scanning QR code. We use Smartphone camera for scanning of the QR code and make run the dataset on the Android-based Smartphone. The result of this research is an android application that can identify objects and produce a sound output of the object name.
