VR and AR are computer-generated 3D simulations that provide users with an immersive experience. VR works by immersing the user into a virtual world, while AR superimposes digital information onto the real world. The main components of both technologies include hardware such as sensors and cameras, and software such as development tools. Uses of AR and VR vary from medical training to entertainment and gaming. The difference between AR and VR is the virtual element ratio, the way they work, and whether or not a headset is required.
