Indoor navigation is challenging due to the unavailability of GPS and complex indoor spaces arising from incremental building architecture. InNav contributes to inclusive service design to find your way in complex indoor environments and services like healthcare, transport terminals, offices or any other large public buildings.

India has the largest visually impaired population in the world, and the number of elderly amongst us is rising every year.

In the present times, outdoor navigation has become simple and accessible, thanks to GPS. Applications like BlindSquare and Be My Eyes make this technology helpful for even the visually impaired. Indoor mobility is more challenging because of the increasing complexity of indoor spaces, unavailability of open standards for structured navigation support and lack of orientation and/or mobility training. These places impose many challenges as often the users are first time or infrequent visitors and thus do not have a prior point of interest or landmarks information.


The Solution

InNav is based on a building map annotated with navigation-related infrastructure including data suitable for visually impaired as input and is capable of handling the user related navigation queries to make the building accessible.


Key Features:

    1. Is an inclusive solution
    2. Follows an open building annotation protocol
    3. Is a scalable model
    4. Simple user interface

User End

    • Responsive Web based and android applications with simple interphases.
    • Accessibility features like complaint and suggestion registration.
    • Image & sound based landmarks for visually-impaired users

Admin End

    • Web based application with a simple UI
    • Annotation tool allows for easy and flexible annotation
    • Multiple versions maintained
