Virtual Reality (VR) is a computer-simulated three-dimensional image or environment. Users wear specialist electronic equipment to explore and interact with the virtual world, and to manipulate objects or perform certain physical actions. Other names for Virtual Reality are Artificial Reality, Augmented Reality, Cyberspace, Telepresence, and Virtual Environment.
To connect to the virtual world, the user wears specialist equipment to track their movements and to receive advanced visual, audio, and touch technology to simulate their senses. As the user moves and their perceptions change, the virtual world adjusts in real-time. The goal of Virtual Reality is for users to experience immersion.
Personal Computers (PCs) with advanced graphics cards can run Virtual Reality systems. To access the virtual world, users wear specialist electronic equipment, particularly Head-Mounted Displays (HMDs). Virtual Reality Gloves and Motion Trackers are other examples of virtual reality equipment.
