Virtual reality is a computer-generated environment that allows a user to interact with three-dimensional images. It is often used in video games, simulations, and training programs. Virtual reality can create realistic environments that are not possible to experience in the real world.
Virtual reality technology has come a long way since its inception in the early 1950s. Early virtual reality systems used large, expensive computers to generate crude images. Today, virtual reality is created using powerful graphics processors and software that can create realistic environments.
Virtual reality is used in a variety of settings, including education, healthcare, entertainment, and business. In education, virtual reality can be used to create simulations that allow students to learn in a safe and controlled environment. Healthcare professionals can use virtual reality to train for difficult procedures or to treat patients with conditions such as post-traumatic stress disorder.
Introduction to Virtual Reality
Virtual reality (VR) is a simulated experience that can be similar to or completely different from the real world. Applications of virtual reality include entertainment (e.g. video games) and education (e.g. medical or military training). Other distinct types of VR-style technology include augmented reality and mixed reality.
A person using virtual reality equipment is typically able to “look around” the artificial world, move about in it, and interact with virtual features or items. The effect is commonly created by VR headsets consisting of a head-mounted display with one or two small high-resolution OLED or LCD monitors providing separate images for each eye, stereoscopic headphones delivering sound to each ear, and head motion tracking sensors. Some VR systems also include tactile information, generally known as haptic feedback.
Haptic feedback is the sense of touch that can be simulated in virtual reality. This can be used to create the sensation of being able to touch, feel, and manipulate virtual objects. Most VR systems use some form of haptic feedback, which can be as simple as rumble motors in-game controllers or as complex as full-body suits that provide a variety of sensations.
The User Interface
The user interface is the way in which the user interacts with the system. There are many different types of user interfaces for virtual reality, including head-mounted displays, hand controllers, and body tracking sensors.
Head-mounted displays (HMDs) are the most common type of VR headset. They provide a stereoscopic image that covers the entire field of view and can be used with or without eyeglasses. HMDs typically have two small displays, one for each eye, that create a three-dimensional image. Another type of VR headset is the binocular headset. This type of headset does not provide a stereoscopic image, but it does offer a wider field of view than an HMD.
Hand controllers are used to interact with the virtual environment. They can be in the form of a traditional game controller, a glove, or a wand. Body tracking sensors are used to track the user’s movement in the real world and translate it into the virtual world. These sensors are often worn on the body, such as on the wrists, ankles, or chest.
Virtual reality systems often use a combination of these different types of user interfaces to provide the best experience for the user.
