Globally indoor spaces are still by and large inaccessible to visually impaired without sighted assistance. 
The situation is even poorer in low-resource countries where regulations are weak, design including signage 
are either non-existent or even if present nonstandard. Apart from navigation issues, the protruding objects 
in the corridors which are not uncommon create safety concerns as well. The prime objective of the proposed 
research is to look at the problem of indoor navigation of blind and visually impaired (BVI) in a holistic manner 
taking into consideration the built infrastructure prevailing in India and other low-resource countries. 
The work would involve both design and innovation in accessible digital mapping, semantic localization and 
design interaction along with prototyping and user validation focusing on indoor spaces. Even globally the field 
is in a very nascent stage and considerable work is required to develop a versatile indoor navigation system and 
to define performance metrics to assess effectiveness of solutions. Working along with ASSISTECH, it is expected 
that apart from prototyping, we would also be able to validate the research with a pilot in couple of buildings 
including in one of the large hospitals in Delhi.
