What is Virtual Reality?
Virtual reality (VR) is a computer-generated simulation of a three-dimensional Environment that can be interacted with in a seemingly real or physical way by a user. VR technology immerses users in a digital world through specialized headsets that display stereoscopic images and track head movements, creating a sense of presence and depth.
How VR Works
VR systems typically consist of the following components:
- Headset: This is the primary device that displays the virtual environment. It usually includes two lenses for each eye, creating a stereoscopic view, and sensors to track head movements.
- Controller: These are handheld devices that allow users to interact with the virtual environment. They can be used to manipulate objects, navigate, and perform actions.
- Computer: A powerful computer is required to generate and render the virtual environment in real-time.
- Software: VR software creates the virtual world, including its graphics, sounds, and interactions.
Types of VR Systems
VR systems can be categorized based on their level of immersion and interaction:
| Type | Description |
|---|---|
| Non-immersive VR: This type of VR uses a computer screen to display the virtual environment. Users interact with the environment using a mouse and keyboard. | |
| Semi-immersive VR: This type of VR uses a large screen or projector to display the virtual environment. Users can interact with the environment using controllers or other devices. | |
| Immersive VR: This type of VR uses a headset to create a fully immersive experience. Users can interact with the environment using controllers or other devices. |
