May I ask what is the reason why I get dizzy when I watch a 3D TV?

I believe that the landlord also sees the shutter type 3D TV,It is said that the current 3D TV is like this,Using low-tech shutter technology,I heard that the shutter type is achieved through the repeated alternating closure of the left and right lenses of the glasses3D effect,You will be dizzy after watching for a long time。

The image quality is not clear enough, and the refresh rate is not high enough.

Samsung's is OK, and the landlord will know it when he goes to the store to experience.

Dizziness is to look at people, looking at 3D pictures, dizziness is also a normal physiological reaction, some people are not used to it, people who are used to it are not good to watch for a long time, there are now naked-eye 3D TVs, this kind of TV can really see 3D stereoscopic pictures within a certain angle, not very practical, really

The technology is not mature enough, if you don't have a special need, it is not very recommended for you to buy

3DThe TV should be cautious when buying,Because most of the current 3DTs are very backward in technology,The picture is flickering,The color will also be distorted,It's very uncomfortable to watch,The glasses also affect eyesight。

3D TV is dizzy. I'm tired

First of all, some people lack the ability to adapt to involuntary vision, and even get dizzy even when watching 2D movies.

Let's say you're sitting in a car, and your head almost inevitably shakes because of the bumps in the vehicle, so your vision will shake with it. During this period, there are various synchronized perceptions such as vision, touch (force on the body), and balance (swaying).

But when you switch to the drag racing scene in the movie, the picture mimics the violent shaking of the driver's vision, but you sit in the audience and don't move. Compared with the sensory experience of daily life, touch and balance cannot match visual signals, and some people with poor body coordination will become "dizzy". It's like "motion sickness", but the cause is just the opposite.

Fortunately, under the continuous training of modern people on various screens, their adaptability to this kind of involuntary vision has been very high.

Secondly, for 3D films, although the picture only adds the dimension of "depth", it once again leads to a certain "dissonance".

Human beings have a wealth of daily experience in observing three-dimensional things, and the human eye has full control over the visual focus: we can not only look at our fingerprints, but also appreciate the scenery in the distance, all of which rely on the brain's active adjustment of the eyes, and "far and near cannot be both".

Back in 3D movies, the focus of the movie is actually locked on the screen, and we don't need to pull it back when a bullet flies at us in the frame – but unfortunately, many people do this subconsciously. As soon as the focus leaves the screen, the picture becomes blurry, and we subconsciously push the visual focus back to the screen again.

In such a "back and forth" state of see-sawing, the human eye is very easy to get tired. Coupled with the aforementioned multiple perceptions out of sync (compared to 2D, we have less perceptual training for 3D images), the proportion of "motion sickness" naturally increases sharply.

In addition, the nervous tension caused by certain contents of the 3D picture (such as the bullets flying in the aforementioned area) will also exacerbate the "halo 3D" to a certain extent"reactions.

To sum up, the key to watching 3D movies is the two words "calm"....Let them make a fuss, you meow at the screen, and leave ...... anythingHowever, this may not be the ...... of watching a movie

Some movies have poor 3D effects and will cause people's physiological reactions, but good 3D will not.

This is 3D vertigo, and the reason for the vertigo is that the picture is too realistic, which makes you feel like you are there, and then your body makes a wrong judgment that you are doing a vigorous exercise, or that you are in a state of being in the picture. The nerve center automatically recognizes the falsity of the movement and suppresses the nerve impulses transmitted by vision, but because the picture is realistic, the nerve center believes that it is true, and at the same time the other motor receptors do not feel any movement, so the nerve center strongly sends out vertigo instructions, hoping that the human body can stop and get out of this ominous situation.

The left and right eyes see things differently.

Because the change of reference made his brain flutter.

There is a great deal of unpredictability, and it is responsible for feeling the balance of the body.

To sum up, this is 3D vertigo.

People through hearing, this is your affirmation of me. These motor receptors are very sensitive, and some people are extra sensitive, and the nerve centers can cause people to feel uncomfortable, so the nerve centers are at a loss: some people are less sensitive, and it helps me to improve myself.

However, the strength of this self-protection mechanism is clearly different from person to person. ”

The solution is to play CF.,You can continue to play after recovery.,Originally, if the picture of the game is not so realistic.,So simply send out the command of vertigo.,Rest for a while after feeling unwell.,The cause of 3D vertigo is roughly,The various sensory organs of human beings are highly coordinated and cooperative,It will gradually adapt to 3D games,For example, dizziness,If the landlord is satisfied with my answer。 When the amplitude or frequency of movement is felt exceeds an appropriate value. For example, there is an organ called "vestibular" in the inner ear, which is controlled by the nerve center to respond appropriately, and I don't know which signal to believe, because the sensing speed of various motor receptors is not exactly the same, such as the direction and acceleration of the human body's movement, and even contradiction, at the same time, other motor receptors (such as the ear vestibular organ) do not feel any movement, nausea, and get rid of this ominous situation, because of the magnitude.

There is also a special optic nerve in the eye to sense movement, and high-frequency movement can cause damage to the human body. Another possible cause of motor vertigo is that the nerve centers strongly send vertigo commands, which are believed to be true, but because the picture is realistic, they transmit the perceived motion information to the nerve centers. After a long evolution, hopefully the human body will stop.

I hope my answer will be helpful to the landlord in dealing with the effects of exercise on the human body. After a long period of evolution. This is actually a self-protection mechanism that causes discomfort in the body and suppresses the nerve impulses from vision, a fact that has been encoded into the human DNA and continues to circulate so that the motor signals sent to the nerve centers are different, such as those who are prone to motion sickness

The optic nerve perceives large and high-frequency movements, such as those who are not prone to motion sickness: when the frequency of movement is too high, so as to achieve the purpose of slowing down or even stopping the movement, this situation is very contradictory and ominous for the nerve center, which will automatically identify the falsity of the movement, please evaluate my answer when adopting. , visual and tactile senses to obtain information about the external environment, and objectively achieve the purpose of preventing the continuation of the current movement.

The imaging principle of 3D TV is to use shutter glasses to close quickly in turn, so that the left and right eyes can see different TV screens. However, due to the existence of visual persistence, when watching 3D TV programs, the human eye will perceive "overlapping images with a certain distance", which is another factor that causes 3D "ghosting" and directly causes "dizziness". And when watching fast, intense football matches or moving pictures for long periods of time, dizziness and fatigue are exacerbated.

How to overcome dizziness?

In order to reduce the occurrence of ghosting, it is necessary to maintain the coherence of the 3D picture, so the refresh rate of the panel should reach at least 120Hz, and the higher the refresh rate, the smoother the picture and the better the 3D effect. Because of this,In the 3D TVs launched by many manufacturers,120Hz or 240Hz technology has become standard。

The high refresh rate means that it is technically possible to achieve **400 frames per second (taking 400Hz as an example), eliminating smearing and presenting dynamic images clearly. When viewing a 3D program with active shutter glasses, you can see 200 frames of slightly different images for the left and right eyes, giving you a truly immersive 3D audiovisual experience.

For example, LG's LX9500 (400Hz), Samsung C7000 (12 times CMR new dynamic technology) and other products. It is worth mentioning that,Compared with2DLCD TV,3DTTV is only implanted3D image processing chip,Its main body is still LCD TV。 Moreover, in the case of limited 3D World Cup film sources and unresolved program broadcasting, watching the game through 2D is still the first choice for many consumers.

In this case,As the bearer of LCD TV70%**,It still plays the role of 3D TV quality determinant。 The most widely used IPS hard screen, black crystal panel and Sharp X-Gen panel in the field of high refresh rate technology have better performance.

Why do I get dizzy when I experience VR?

It's because the visual sense of the movie is very good. And the sound is also very loud, so it will cause some people to get dizzy.

Because 3D movies look more three-dimensional, you will feel a little dizzy.

Because 3D is more three-dimensional, people will feel dizzy in their heads.

There will definitely be a little feeling, and watching 3D for a long time will make people highly nervous, so they will be dizzy.

Because watching a movie will follow the feeling of action, such a movie will have an effect.

Because the body's balance adjustment system is so good, you will feel dizzy.

This is because some people can't get used to 3D images, so they feel dizzy.

The main reason is that its picture sense is too strong, and its real existence is too high.

Because there may be some people who are not very physically fit, so it will be like this.
