1. A method for detecting obstacles in an environment of a user in real-time, the method comprising:
generating, by a wearable Light Amplification by Stimulated Emission of Radiation (LASER) scanner, a LASER beam towards each of a plurality of regions in the environment of the user, wherein the environment comprises an arc with respect to a current position of the user, wherein the arc comprises a predefined radial distance, a predefined angle, and one of a predefined height or a predefined depth, and wherein the arc is divided into the plurality of regions based on a corresponding angle and one of a corresponding height or a corresponding depth with respect to the current position of the user;
receiving, by the wearable LASER scanner, a feedback signal based on reflection of the LASER beam from an obstacle located in at least one of the plurality of regions;
transforming, by the wearable LASER scanner, the feedback signal from the at least one of the plurality of regions into obstacle information through a Machine Learning (ML) algorithm, wherein the obstacle information comprises an angle and one of a height or a depth of the obstacle with respect to the current position of the user;
activating, by a wearable device, one or more of a plurality of pressure elements of an obstacle matrix based on the obstacle information of the at least one of the plurality of regions, wherein the plurality of pressure elements is arranged in rows and columns in the obstacle matrix, and wherein each of the plurality of pressure elements corresponds to each of the plurality of regions; and
generating, by the wearable device, a predefined pressure through each of the one or more of the plurality of pressure elements of the obstacle matrix based on the obstacle information of the at least one of the plurality of regions, wherein the one or more of the plurality of pressure elements correspond to the at least one of the plurality of regions.
