How will virtual reality change our world? This is a question that many people are asking as the technology continues to develop. Virtual reality has the potential to change the way we interact with the world around us. It could provide new ways of experiencing and understanding our environment. It could also lead to new methods of communication and collaboration. The possibilities are endless. Only time will tell how virtual reality will change our world.
What is 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 History of Virtual Reality
The history of virtual reality is a long and complicated one. The term “virtual reality” was first used in a science-fiction context in the 1930s, but it wasn’t until the 1950s that the technology began to be developed. In 1957, Morton Heilig created the Sensorama, which was an early attempt at creating a virtual reality experience. The Sensorama was a machine that would allow users to experience simulated environments, such as riding a roller coaster or being in a car chase.
In 1968, Ivan Sutherland created the Sword of Damocles, which is considered to be the first head-mounted display (HMD). The Sword of Damocles was a very primitive HMD that was incredibly heavy and uncomfortable to wear. Despite its flaws, the Sword of Damocles was a significant step forward in the development of virtual reality.
In the 1980s, several companies began developing virtual reality systems for use in gaming and entertainment. These early VR systems were very expensive and not very user-friendly. In the 1990s, Sega released the Sega VR-1, which was a head-mounted display that was designed for use with the Sega Genesis console. The Sega VR-1 was not a commercial success, but it did help to spark interest in virtual reality gaming.
In 2010, Oculus Rift (now Facebook) was founded with the goal of bringing affordable and high-quality virtual reality to the masses. In 2012, Oculus Rift released a prototype of their first HMD, the Oculus Rift Development Kit 1 (DK1). The DK1 was a success and paved the way for the development of the Oculus Rift Consumer Version 1 (CV1), which was released in 2016.
Since then, virtual reality has become more and more popular. In 2017, Sony released the PlayStation VR, which is a virtual reality system that works with the PlayStation 4 console. Microsoft is also working on their own virtual reality system, the HoloLens. There are many other companies developing virtual reality systems for a variety of different platforms as well.
How Does Virtual Reality Work?
Virtual reality is created using a variety of different technologies. The most common type of virtual reality system is the head-mounted display (HMD). An HMD is a device that is worn on the head and has a display for each eye. The display creates the illusion of being in a virtual environment.
Most HMDs use either LCD or OLED displays. These displays are capable of creating sharp images with a wide field of view. They also have low latency, which means that there is little to no lag between what the user sees and what they experience in the virtual world.
HMDs are often paired with hand controllers, which allow users to interact with the virtual environment. Hand controllers can be simple, like a controller for a video game console, or they can be more complex, like gloves that track the movement of the user’s hands.
There are also a variety of other input devices that can be used with virtual reality systems. These include joysticks, gamepads, keyboards, and mice. Some systems also use voice recognition and eye-tracking.
Virtual reality systems use computer graphics to create realistic images. This is done by using a process called rendering. Rendering is the process of creating an image from a 3D model. The model is made up of polygons, which are then mapped to a 2D surface. The final image is then displayed on the screen.
Virtual reality systems must be able to render images at a high frame rate. This is because the human brain can process images that are displayed at a rate of 60 frames per second. If the frame rate is too low, the user will experience a condition called simulator sickness, which can cause nausea and vomiting.
Some virtual reality systems use pre-rendered images, while others use real-time rendering. Pre-rendered images are created ahead of time and stored in memory. Real-time rendering calculates the image as it is being displayed. Real-time rendering is more demanding on computer resources, but it provides a more immersive experience for the user.
Virtual reality systems must also have a way to track the user’s movements. This is so that the system can update the image on the screen to match the user’s point of view. There are a variety of different tracking technologies that can be used, including optical tracking, magnetic tracking, and accelerometer-based tracking.
Optical tracking uses cameras to track the position of the user’s head. This information is then used to update the image on the display. Magnetic tracking uses sensors to track the position of a device that is worn by the user. This information is also used to update the image on the display. Accelerometer-based tracking uses sensors to track the acceleration of the device. This information is then used to estimate the position of the device.
Virtual reality systems often use a combination of these tracking technologies to provide more accurate tracking of the user’s movements.
Potential Applications of Virtual Reality
Some potential applications for virtual reality include entertainment, education, research, and creating augmented reality experiences. Virtual reality can be used for video games or movies, medical or military training, studying human behavior, or exploring other planets. Additionally, virtual reality can be used to create simulated environments that are not possible in the real world.
Healthcare
Healthcare is one of the industries that is most likely to be disrupted by VR. VR can be used for training doctors and surgeons, as well as for patient rehabilitation. VR allows healthcare professionals to gain experience in a safe and realistic environment, without putting patients at risk.
