VR equipment of 3 dof and 6 dof what?

today we are here and you take a look at about 3 dof and 6 dof of VR equipment what? To solve this problem, need to understand the working principle of VR devices, then we'll take a look at.

a lens imaging features of the display cover on the eyes, where people to watch, in the display shows the direction of the corresponding scene picture, thus to make people feel themselves in a virtual space is infinite.

this function realization consists of the following sections infrastructure:

1. Processor

processor that computing core, used to calculate and generate the image, and according to the gyroscope data calculate your posture positioning, etc. In order to prevent dizziness caused by speed is not synchronized, VR devices require image refresh rate of 90 hz, this case is high requirement of operation speed of the processor. So, in general, good VR equipment processor chip performance index is very important.

2。 Display

the right and left eyes separately to display images. Usually when we say 2 k screen VR glasses, refers to a block the size of the long side of the screen, such as the size of 2 k * 1 k. But if: monocular 2 k, is refers to the short side of the screen size is 2 k. On the market at present the mainstream configuration of monocular 1. About 5 k. The higher the screen resolution, requirements for the processor which is equipped with the more powerful.

3。 Lens

if the monitor directly in front of people, is the human eye can't see clearly so close, so the meaning of the convex lens slices in VR devices, it is through the refraction of light that will display on the screen image closer to the retina position, make the person's eye can easily see almost posted in front of screens.

4。 Gyroscope

if you want to let the VR devices in the display picture with the movement of the head and real-time changes, you must want to know the head orientation. For example, when you look up dressed in VR equipment, the display in the eyes, need to show you in real time the sky in the virtual world, when you look back, display is to show you behind the scene of a simulated real return. How to detect VR devices for the action that you look up? The gyroscope is needed for cooperation. Specific gyroscope principle here temporarily not open, as long as known, it can be used to detect a person ( Objects) Direction and posture in the space.

on the same day, just 360 & deg; Display is not enough, is bring us strong immersive VR equipment, is because you can see not only a comprehensive range of virtual scene, also can through VR equipment with the virtual scene in real-time interaction, the true charm of VR games.

depending on the degree of interactive, we often hear the VR equipment involved in the 3 dof and 6 dof etc.

dof: degree of freedom, namely the degree of freedom.

three dof refers to the degree of freedom, there are three rotation Angle and 6 dof is refers to, in addition to the three rotation Angle, coupled with the up and down, front and rear, around three position related to the degrees of freedom.

so, when we say 3 dof VR glasses or VR devices, refers to the VR devices can detect the free rotation of the head in different directions, but can't detect space displacement around the head. The 6 dof VR devices ( Glasses) , in addition to detect the rotation of the head of the changes in the Angle of view, will also be able to detect because the body moving up and down around before and after the change of displacement.

3 dof VR devices can be used to see VR movies in general, and to play a game with the scene of the interaction, the need to be able to support a 6 dof VR devices, so we can experience the obstacle in the game, dodge bullets and monsters, and jump off a building, mountain climbing, skiing, etc. The true feelings.
