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 person using special electronic equipment, such as a helmet with a screen inside or gloves fitted with sensors.

VR technology provides a completely immersive experience, allowing the user to step inside and interact with a digital environment as if it were real. This can be used for a wide range of applications, including gaming, entertainment, education, training, and more.

In gaming, VR can provide a completely immersive experience, allowing the player to feel as if they are inside the game world. In entertainment, VR can be used for immersive experiences such as virtual concerts or movies. In education and training, VR can provide hands-on and interactive learning experiences, allowing users to practice skills in a simulated environment.

VR is a rapidly growing technology, with new and advanced VR devices and applications being developed all the time. As the technology continues to improve, it is expected to become even more widely used and to have a significant impact on a range of industries and areas of society.

Type of Virtual Reality

1. Non-Immersive VR: Non-immersive VR provides a limited or partial VR experience, typically through the use of a desktop computer or a smartphone. The user typically sees a small portion of the virtual environment at any given time and has limited interaction with the virtual world.

2. Semi-Immersive VR: Semi-immersive VR provides a more complete VR experience than non-immersive VR, typically through the use of a headset and hand-held controllers. The user is able to see and interact with a larger portion of the virtual environment, but still has some awareness of the real world.

3. Fully-Immersive VR: Fully-immersive VR provides the most complete and realistic VR experience, typically through the use of a headset, hand-held controllers, and body tracking devices. The user is fully immersed in the virtual environment and has no awareness of the real world.

4. Desktop VR: Desktop VR involves using a computer to create a virtual environment that the user can interact with. The user typically wears a headset and uses hand-held controllers to navigate the virtual environment.

5. Mobile VR: Mobile VR involves using a smartphone or tablet to create a virtual environment that the user can interact with. The user typically inserts the smartphone into a headset and uses hand-held controllers to navigate the virtual environment.

6. Cave Automatic Virtual Environment (CAVE): A CAVE is a room-sized, fully-immersive VR environment that uses multiple projections to create a virtual environment that the user can walk around in.

Difference between Aurmented Reality and Virtual Reality

	Augmented Reality (AR)	Virtual Reality (VR)
Definition	A technology that enhances the real-world environment with digital information and content	A technology that replaces the real-world environment with a simulated one
Delivery Method	Typically delivered through a device such as a smartphone, tablet, or AR headset	Typically delivered through a VR headset that completely covers the user's field of view
User's View	The user sees the real world with digital information and content overlaid on top	The user sees a completely simulated environment with no view of the real world
Interaction with Environment	The user interacts with the real world environment, with digital content overlaid on top	The user interacts with a simulated environment and digital content, with no interaction with the real world
