1. A device configured for assisting a visually impaired user to grip an object, the device comprising: a camera; a central processing unit, comprising: a memory; and a processor coupled to the memory, wherein the processor is configured to execute program instructions stored in the memory to: receive an image of an object in real-time, wherein the image is captured by the camera; identify a reference image corresponding to the image by comparing the image with reference images present in a database; identify a reference tactile image corresponding to the reference image, wherein the reference tactile image is stored in the database; generate a first set of audio instructions for assisting a visually impaired user to grip the object based on the reference tactile image; receive a tactile image from a tactile glove put on by the visually impaired user; compare the tactile image with the reference tactile image to identify pressure variation data corresponding to one or more points in the tactile image and the reference tactile image; and generate a second set of audio instructions for guiding the visually impaired user to grip the object, wherein the second set of audio instructions is generated based on the pressure variation data.
