Also called VR. Virtual Reality describes a three-dimensional, computer-generated environment that is experienced through a headset. The user may also wear special gloves to help interact with the virtual world. VR is currently being used in computer games and entertainment but is also in other fields.
VR simulations safely train humans to handle situations that are too dangerous or impossible to experience repeatedly, such as fighter pilots, surgeons, soldiers, and athletes. As the cost of VR is coming down, it is becoming more common. Experts predict we will see VR integrated into mainstream education and other mainstream applications soon.
