AR, VR and MR technologies and their implementation in libraries

In this paper, the investigator has studied AR, VR and MR technology. These are innovative computer technologies. in virtual reality, the user goes to the virtual world, feel it and interact with it. They don't have the sense of the real world. In augmented reality, we can bring virtual objects into the real world. The investigator has studied AR, VR and MR apps and libraries that are using such technology in their libraries. With this, the investigators suggested some library services and shared their experiences of the implementation of these technologies in the library.
