The concept of virtual reality is primarily based on creating immersive, computer-generated environments that simulate real or imagined experiences. Users interact with these environments through specialized hardware like VR headsets and motion-tracking devices, which provide sensory feedback to enhance realism. Virtual reality often employs techniques from 3D modeling and gaming technology to construct visually rich and interactive experiences. It is used in various sectors, including entertainment, education, and therapy, to provide engaging simulations that enhance learning, training, or leisure activities.
