Indoor Navigation System for Visually Impaired using Real Time 3D Depth Sensing Sensor

This paper portrays a novel idea for aiding the visually impaired individuals to navigate indoors freely without depending on anyone but only by using a Smartphone. The system has been developed in such a way that it is feasible on any android device, having a depth sensing image sensor. The application makes use of an Indoor Positioning System (IPS), that can use different types of sensory information to locate objects or people inside a large complex. Navigating indoors is the most challenging. It is purely an application for the android Smartphone which uses Augmented reality (AR) and the visually impaired obtains navigation instructions in the form of audio. This can help provide step by step walking independently.The proposed system works with AR Core by Google, with the help of unity engine to process the images in augmented reality to detect the obstacles while navigating indoor and sends an audio message to the user to help him/her to navigate.
