Virtual reality in the context of the digital world is a simulated environment created using systems and software. Such an immersive environment, which can mimic real world or can be entirely fictional, can engage most of human senses including sound, sight and even touch. Users can move, look, listen and even touch virtual objects around them. Depending on the complexity and functionality, VR systems can incorporate a range of technologies including but not limited to motion sensors, multidirectional cameras, head mounted display screens along with powerful fast processors. VR was initially used primarily in the military and aviation sector for training purposes. Now other sectors including gaming, medicine, retail and reality have also embraced this technology.
