How to avoid using VR dizziness?

How to solve vertigo

Now that the problems caused by vertigo, then the question becomes, how do you solve it? In fact, faced with different motion sickness have different solutions, but solutions are varied.

To enhance the strength of the device itself

For visual motion sickness the best solution is to upgrade the device itself, if all devices are capable of 120Hz or more of the effect, it will visually see the screen will be very delicate, increase the speed of operation can also reduce delays, screen tearing crack, flash anomalies, if we see the fine screen, continuously and without delay, it is difficult to appear visual motion sickness cases.

NVIDIA recently released GTC General Assembly on a new technology that can be used as VR field, the use of this technology will reach the screen refresh rate 1700Hz, revolutionized the conventional screen refresh rate value, although for a conventional display is probably not very meaningful, but used in the VR screen may be disruptive.

Content level to avoid dizziness

For analog motion sickness, it is not particularly desirable and simple solution, of course, do not be too concerned about, because many times our body will automatically adjust slowly to adapt to the virtual scene. But if the picture changes too fast by a big margin, it is likely to cause physical discomfort.

So we need to adjust the level of content, such as when we, of course, from what viewing angle can be more gentle show in a virtual scene, how to avoid the appearance of simulated motion sickness.

For this problem, some experienced production team games and content service providers already have some experience, and now there are a lot of scenes and content, adjust the angle by reducing the range of motion and other ways to ease the symptoms.

External factors suppress vertigo

For analog motion sickness, can also rely on external forces to ease, Samsung has demonstrated through a device called a Entrim 4D, he is a pair of headphones, but when used in conjunction with VR would emit weak electrical stimulation of the inner ear. Through electrical stimulation, deceive users, allows users to vestibular illusion that the body is in motion, so the body does not match the vision and will reduce, to the role of remission.

Of course, in addition to the new technology as well as medicine, surgery, etc., but these relatively high risk, may also have adverse effects on the body, viability is relatively low.

Of course, the so-called VR motion sickness can not be regarded as a disease, but our bodies out of a mechanism of self-protection and for a new thing suited state. With the development of technology, and strengthen our resilience, and ultimately will overcome this problem.

Why dizzy with VR helmets?

Whether it is the high price of strong popular hot products or low-cost version of the product is more or less easy to be experiencing a problem, the problem is now most concerned about the field of VR, that is --VR vertigo.

This year a new domestic industry broke out, the field of science and technology is interesting not only concerned about it, real estate, gaming and other fields also has its active presence, yes that is VR industry, as well as the corresponding important product VR helmet. Some people say that this year is the first year of VR is indeed a technology accumulated through a long period of time, VR showing explosive growth this year, countless VR helmets and VR technology team and relevant content and service providers to emerge.

Of course, whether it is expensive or strong popular hot products with low prices have more or less simplified version of the product encounters a problem, the problem is now most concerned about the field of VR, that is --VR vertigo.

What is VR vertigo

In fact, strictly speaking, it should be called virtual reality VR dizziness motion sickness, also known as VR motion sickness, based on actual usage it can be subdivided into two different symptoms, are simulated motion sickness and visual motion sickness. So what is the difference between them, have caused us what kind of impact?

Simulation of motion sickness

Simulation of motion sickness is also called, in fact, the term does not appear with the VR come as early as the advent of television, when there is, and it is a kind of disorientation evolved, somewhat similar to seasickness, motion sickness, but is caused due to prolonged watching the screen.

Visual motion sickness

Visual motion compared to more simply, not because our body causes, but because of problems caused by the device itself, such as screen refresh rate, delay and so on.

There is also the problem of refresh rate, the refresh rate can be interpreted as the number of frames per second, the frequency of the screen, in general, more than 60 frames per second picture looks much better, VR helmets area that requires the refresh rate is 90Hz or more screen 90 per second will have a better effect.

3, showing the three-dimensional information

Computer intake reality images, static images, dynamic images, the sound image can be interactive, these are two-dimensional.

The VR is three-dimensional image can be interactive, able to restore more information.

For example, the depth of information - "VR in which metaphors depth cues" This is a new dimension, in this dimension, you can turn your head.

As I said in the "six degrees of freedom of the VR," said the host side of the VR is six degrees of freedom, can not only get your head in sports parallax images by turning, but you can move around and even head ...... probe into the three-dimensional virtual objects, and to see what it contains.

Human reality using the computer to restore the information, and with the development of collection equipment. "Distortion" becoming less and less able to restore the information more and more, higher and higher dimensions:

• Records of text and drawing paper,

• phonograph to record sound,

• Movie recording film

• RGB recording a two-dimensional digital image information

• a second film containing 24 images

• three-dimensional interactive games, animation

• panoramic views in all directions have a stereo camera camera (capture 360-degree visual information of three degrees of freedom, you can watch mobile terminal VR)

• In the future, with the four-dimensional light field, will be able to restore more information - six degrees of freedom lytro panoramic light field camera that footage, although only a static picture, you can move it allows the shooting scene walking.

• Currently panoramic camera panoramic video shoot out more than three degrees of freedom, only panoramic light field camera can shoot out of the six degrees of freedom of the picture (due to the current computer performance limitations, so it can only shoot a single frame still picture).

A scene • published some time ago lytro light field camera a picture --755 megapixel light field camera 40k. (However, it is equivalent to three degrees of freedom plus a function of moving back and forth, but not the full six degrees of freedom, which means you can not go behind the object, but still a very black & ~)

•

• With the development of quantum computing may also have a five-dimensional light field, you can restore the humanity of all the visual information.

Finally, the computer has collected all the space of the whole world, five-dimensional light field of visual data all the time, you can view any information anytime, anywhere on your computer.

2, the immersion

From the aspect of immersive point of view, VR is just a bigger screen, away from the eyes closer to the field of view angle greater share visual information provides richer.

From the visual and formal terms,

We all know that more and more large-screen cinema, large imax, even semicircle, curved screen IMAX, why not let the screen attached to your eyes?

Accounting perspective because the screen is too large, when the screen camera movement, but did not move your head, it will lead to motion sickness.

Because the big screen is the trend, and breaking this level large screen makes you feel content being projected, even more exacerbated this important trend.

In VR, the three degrees of freedom of movement VR tracking (Orientation Tracking) so that you can easily turn your head, the screen produce a corresponding change. (On the other hand, the direction of rotation also had a motion parallax, get behind talk about more "depth information.")

Therefore, the conventional two-dimensional image on the screen, a small screen is limited, and is two-dimensional information, and VR is three-dimensional.

So many people only see this, that VR is a pseudo-demand, just to experience the upgrade.

VR experience

I found out the first year have to watch clips and shot change film "The Great Train Robbery" of the audience, I found that they are often like the circus, concerts, opera aristocratic "user."

Not difficult to imagine, when people have the opportunity to see the film, it had to experience this new media demand, and this demand prompted the development of the birth of cinema and television.

And this group of users are most likely to be attracted to go!

Economics there is a word called "fungible commodity."

A hundred years ago, like listening to the radio users to buy a TV, so before you start eating favorite radio ash.

Now, one would have liked to play mobile games every night and recharge for its paying customers, began to see live, and live his time was occupied, he began to live my sister paid a reward.

Similarly, like in the computer user to buy a movie since PS and XBox, it is no longer like to watch movies.

A medium, is likely to be attracted to the more advanced media.

For example, I, since buying gearVR, rarely play mobile games.

Of course, we also need a by VR VR feature will be a demand point of detonation.

We need a VR world Steve Jobs.

Prior to the first film, such as 1890, when there movie playback technology, and then may put some sporting events, farce, like the scenes of life ...... but the biggest feature is the only one, unchanging static shots, no clips.

But "The Great Train Robbery" used some editing techniques, such as cross-splicing (cross cutting), a plurality of positions of the camera display (multiple locations) and some special effects.

Therefore, "The Great Train Robbery" may be said to be the ancestor of the film.

In the VR community, we also need such a work.

What should pay attention to buy 3D vr virtual reality glasses(three)

8, the controller

Google Cardboard V1 is Google's first release was the first side has a magnet button, push the button, the first significant fall off immediately. Of course, this head was not available for all phones. And there was another head capacitive touch screen, the user can not take off the head and was also able to control the phone screen. In addition, the open head was naturally not have these problems: you can simply touch the screen.

However, there are a lot of fully enclosed head was no such button. These companies also cooperate with many Google Cardboard applications, because the designers are aware of this flaw, hope that the current application can interact through the pupil primarily focused way. While other manufacturers are trying to head significantly by bundling external remote control to solve this problem.

In general, to ensure that the user experience, or select the button comes first display, or choose directly operate the phone, or select with external remote control.

9, the price

The current head of mobile VR Prices vary significantly. Open folding head significantly in price from $ 5 (VR Fold on AliExpress) to $ 22 (GoogleTech) ranging from cardboard head was the price at between $ 1-30 US dollars, while the price of the plastic tip was to go up to to more than $ 100.

Some already on the market for some time was the head of the big brand price will be high, such as Merge VR $ 100, Fibrum priced at $ 130, Homido priced at $ 80 and Zeiss 3D vr virtual reality glasses One sells for $ 120. I personally think that these products do not have a good price, unless the user really likes a certain style, but also willing to make sacrifices.

Currently the price of virtual reality head was between 20-50 US dollars is relatively reasonable. My favorite products, including Mattel View-Master, storm mirror 3 and LeNest. These products are sold behind the company seems to be a lot of products, can continue into research and development into, and the number go up, the price will be down.

10, use of comfort

For me comfort is the most important factor when I purchased the first VIP considered. You'll like each use but also the first mobile phone sets off head was it? I picked are directly inserted in use. Most open-lightweight head was not the problem: the phone is placed in the support frame is like. LeNest solution is very simple: open the case will be able to go directly into the phone, then put the shell off trying to be difficult.

But some head was very complicated. For example Freefly VR, before each user must first look at the instructions, because the method next time do not remember. If the head was embedded in the phone method is too complicated, switching applications, play a new video, and even change the settings will be very troublesome, because they have to use the phone's touch screen, the buyer needs to be carefully considered.
