BACKGROUND
[0002] Background description includes information that may be useful in understanding the present disclosure. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed disclosure, or that any publication specifically or implicitly referenced is prior art. [0003] Navigation in unknown indoor locations is a difficult task, especially in presence of language barrier. Arrow signs, display boards, guides and reception units have been used previously but such distinctive markers are unavailable from any random location inside a building or a complex of buildings. Therefore there is need in the art to develop a system that can assist a user with directions for navigation in unknown locations. In addition, a query based system for navigation related directions can also provide optimized routes to desired destination to people with impaired vision, special needs and personalized requirements. [0004] Existing literature describes a mobile device based system that provides maps with visual and voice guidance for navigating unknown indoor locations. Another system describes generation of routes including waypoints to unknown destinations based on sensor determining the starting location. An intra-facility way-finding system has been disclosed that generates optimized routes in online and offline modes. A couple of indoor navigation systems are also available that can track a mobile device in transit within an indoor environment. However, none of these systems disclose an electronic visiting card for facilitating query based directions for navigation.
[0005] The proposed device and system pertain to an electronic visiting card that can act as a bridge between a server containing information of a plurality of coordinates of predetermined indoor locations and one or more user devices associated with one or more entities or users. The proposed system can adapt to

changes in the destination map as well as location of the entity with reference to the said map. Visual, audible and vibratory media can be accepted in receiving and responding to one or more queries from the one or more entities.
