dynamically and iteratively generating, by the user device, a mixed reality route to the desired location overlaid over the environment, wherein the mixed reality route comprises directions to reach the desired location;

identifying an occurrence of an activity associated with the user along the mixed reality route to the desired location within the environment;

wherein the activity comprises being stationary at a pre-defined location, falling, slipping, shouting, walking, climbing stairs, erratic biometric parameters, passing specific points of interest, and running;

extracting values of at least one parameter associated with the activity based on data captured for the activity;

comparing values of each of the at least one parameter with an associated predefined threshold; and

sending a notification to a predefined contact based on a result of the comparing.

2 . The method of claim 1 , further comprising scanning, via the user device, the machine-readable mark, wherein the scanning comprises:

reading, via a sensor of the user device, the machine-readable mark; and

extracting the geographical information in response to reading the machine-readable mark, wherein the geographical information comprises layout data of the environment.

3 . The method of claim 2 , wherein the environment is an airport, the desired location is a boarding gate at the airport, and the machine-readable mark is cooperatively coupled to a boarding pass issued to the user.

4 . The method of claim 3 , further comprising, receiving, via the machine-readable mark, data corresponding to the user, wherein the data corresponding to the user comprises personal details and flight details of the user.

5 . The method of claim 4 , further comprising verifying, from the user, the data received corresponding to the user, based on one or more verification checks.

6 . The method of claim 3 , wherein data corresponding to the airport and the boarding gate are received in response to the scanning of the machine-readable mark on the boarding pass.

7 . The method of claim 3 , wherein generating the mixed reality route comprises:

displaying, via the user device, a virtual path and the directions to the boarding gate;

identifying a change in the current location of the user; and

updating, via the user device, the virtual path and the directions based on the identified change.

8 . The method of claim 7 , further comprising displaying to the user, via the user device, distance and time to the boarding gate.

9 . The method of claim 7 , further comprising:

displaying, via the user device, a list of neighborhood locations along the mixed reality route to the boarding gate based on the current location of the user;

receiving, via the user device, a user selection of a neighborhood location from the list of neighborhood locations; and

updating, via the user device, the virtual path and the directions based on the selected neighborhood location.

10 . The method of claim 1 , wherein the machine-readable mark is one of a bar code, a Quick Response (QR) code, and a Radio-frequency identification (RFID).

11 . A system for guiding a user to desired locations within an environment, the system comprising:

a processor; and

a memory coupled to the processor, wherein the memory stores processor executable instructions, which, on execution, causes the processor to:
