Is vr technology the same as holographic technology?

VR: interactive virtual reality experience

VR(Virtual Reality) is a virtual reality technology, which uses computers to provide users with an interactive, immersive and immersive virtual three-dimensional space. Its characteristics mainly include multi-perception, interaction and immersion.

Multi-perception means that VR has not only visual perception, but also tactile perception, motion perception and even taste and smell perception.

interactivity, that is, when users use VR technology, they can interact with it and get the same feelings as in real life, such as disassembling machines and replacing equipment.

immersion means that VR provides users with a realistic environment, making them feel as if they are in reality.

holographic projection: naked-eye 3D imaging

holographic projection technology is also called virtual imaging technology. It is a technology that records and reproduces the real three-dimensional image of an object by using the principles of interference and diffraction.

Among them, phantom imaging is the most mature holographic projection.

Phantom imaging is a technology based on holographic projection. It projects the shot image into the main model landscape in the scenery box, and sets the glass of the scenery box to 45 to reflect the image at the bottom or top, thus giving users illusory and dreamlike visual enjoyment.

The difference between VR technology and holographic technology:

vr forms a closed virtual reality experience space for users through a specific helmet or glasses, allowing users to feel the virtual scene in all directions according to the images in the helmet.

holographic projection does not need to wear any equipment, and users can watch 3D effects with naked eyes.
