Virtual reality

Virtual reality is a technology that creates a simulated environment, often using computer-generated imagery or a combination of real and virtual content, to immerse users in an interactive and lifelike experience. The aim of virtual reality is to make users feel as if they are physically present in a different environment, even though they are typically still physically located in the real world. Virtual reality finds applications across various fields, including gaming, education, healthcare, training, and entertainment. In gaming, users can be transported to fantastical worlds, experiencing games in a more immersive way. In education, VR can provide realistic simulations for training purposes, allowing users to practice skills in a risk-free environment. Healthcare professionals use VR for therapeutic purposes and medical training. The U.S. Air Force has shown using VR for training programs for their new pilots to simulate piloting an aircraft. This allows new pilots to learn in a safe environment and get comfortable before getting in a real aircraft.

Head-mounted display (HMD): Users wear a headset that covers their eyes and ears, providing visual and auditory stimuli. These headsets are equipped with screens that display the virtual environment, and some may also have built-in speakers or headphones for audio.

Motion tracking: Sensors track the user's movements, allowing them to interact with the virtual world. This can include head movements, hand gestures, and sometimes even full-body movements, enhancing the sense of immersion.

Input devices: Controllers or other input devices are used to interact with the virtual environment. These devices can simulate hands or tools, enabling users to manipulate objects or navigate within the virtual space.

Computer processing: Powerful computers or gaming consoles are often required to generate and render the complex graphics and simulations needed for a convincing virtual experience.
