1. A method of managing navigation in a physical environment, the method comprising:
receiving, by a processor, an information dataset from a real-time data feed, wherein the information dataset includes object information, user information, and environment information;
generating a digital twin of a physical environment and a user, wherein the digital twin of the physical environment is based, at least in part, on the information dataset, and wherein the digital twin of the physical environment and the user are actively changing as the real-time data feed provides continuously updated data associated with the information dataset;
simulating one or more factors on the digital twin of the physical environment;
identifying a dynamic landmark from the digital twin, wherein the dynamic landmark is a particular parameter change associated with the physical environment;
determining an accuracy level of the information dataset based on observing the dynamic landmark in the physical environment and the digital twin;
predicting, responsive to simulating the one or more factors, one or more pathways to a destination, wherein the destination is in the physical environment;
identifying a user limitation from the user information and digital twin, wherein the user limitation reflects a physical condition suffered by the user;
identifying a particular pathway from the one or more pathways, based on the user limitation; and
generating one or more binaural auditory notations to the user associated with the particular pathway.
