Virtual Reality (VR) is simply an unreal computerized setting put in place of the actual world. For instance, Facebook adopted VR to connect its users all over the world. Two key headsets involve users in VR, consisting of PC-connected headsets and standalone headsets. As its name, PC-connected headsets must be associated with computers for high-quality virtual involvement, and it’s usually expensive while standalone headsets enable to associate with smartphones which are affordable and more convenient, and easier to use. One remarkable point is some standalone headsets need neither computers nor smart screens, they work on their way and become common and also affordable as well. 360-degree videos and photos are immersive exemplifications for VR headsets. Speaking about the real-life application of VR in education, university is a representative organization building virtual learning content for businesses and universities. Virtual learning is the best engaging way of educational learning as a study result.
Augmented Reality (AR) can be confused with VR but it’s simply virtual objects such as images, videos, and interactive data put in a real setting.

AR is significantly used for E-commerce like buying a chair, customers can see how the chair fit the room and then choose the best chair for the room. There also are two key AR experiences which are Portable Devices and Smart Glasses and AR headsets. Portable Devices can see virtual objects through tablets and smartphones (Pokemon Go is an instance of an AR app that is used on smartphone screens to catch virtual Pokemon) while Smart Glasses and AR headsets need special smart glasses and headsets. With the application of AR in advertising, marketers, and advertisers can reach wider audiences and then increase brand awareness through virtual objects applying to their products/ services in creative ways due to an interactive and more engaging AR experience.

Mixed Reality (MR) is also called Hybrid Reality as MR technology helps you see virtual objects and these objects can interact with the real world, is a type of AR but with more engaging and interactive performance. However, some other kinds of MR are more similar to VR than AR by managing both the real world and virtual settings at the same time. There are two key forms of MR experience, including Holographic Devices and Immersive Devices. Holographic Devices exploit almost transparent glasses to see virtual surrounding objects through holograms while Immersive Devices do not use transparent glasses which shut off the real physical world but use cameras in the meantime instead. Going with the application of MR experience in communications, employees use headsets and set up a collaboration with partners, colleagues so on in the physical setting in the real world, helping virtual meetings and conferences more effectively.
With incredible features from VR, AR, and MR bringing us, these immersive technologies are changing our world by assisting several industrial sectors and increasing the level of development. With the increased awareness of these VR, AR, and MR applications, there will be a lifting demand for all industries in a couple of coming years for a brighter life and prospect.
