Understanding the Basics of Virtual Reality
An Overview of Virtual Reality: Bridging the Physical and Digital Worlds
Virtual reality (VR) is an interactive computer-generated experience that simulates an environment which can be either similar to or completely different from the real world. The concept of VR dates back to the 1960s when the first primitive headset was created by Ivan Sutherland and Bob Sproull at Harvard University. However, the term “virtual reality” was coined by Jaron Lanier in 1987, and it has transformed over the years into a sophisticated technology with an array of applications ranging from gaming and entertainment, medicine, education, to military training.
The Different Types of Virtual Reality: Fully Immersive, Semi-Immersive, and Non-Immersive
There are essentially three types of VR experiences: fully immersive, semi-immersive, and non-immersive. Fully immersive virtual reality provides the most engaging experience and typically involves a head-mounted display (HMD), gloves, and sometimes full-body suits, which are all equipped with sensors to track the user’s movements and translate them into the virtual environment.
Semi-immersive VR provides a partially virtual experience while still maintaining a connection to the real world. It often uses large screens and surround sound to create a more immersive experience than non-immersive VR, but less so than fully immersive VR. Common examples include flight simulators and car driving experiences.
Non-immersive VR is typically limited to the computer screen. Visual immersion is limited, but this type of VR is common in video games and virtual tours of buildings or cities where users can interact with the virtual environment using standard input devices like a mouse and keyboard.
