VR technology is moving toward the general public. While enjoying VR fun, we cannot ignore the negative effects that VR may have on the human body. So, what are the hazards to the human body using VR products?
As an uncle of VR addiction, I wrote to watch everyone play VR:
At present, it is best to play VR (whether it is a host VR or a mobile VR) and it is best to play 10-15 minutes in half an hour, and not more than two hours in a day.
In fact, most people who are not suited to VR are not suitable for playing games on large screens and televisions (especially children under the age of 20). Conversely, those who have the highest level of VR acceptance are those who Movie fans and host game enthusiasts.
I listed a tree diagram, probably summed up the possible adverse symptoms in VR:
First, the vestibular system
Influence of opponent eye coordination
Because the interaction of VR is essentially establishing a "mapping between the hand and the eye", this mapping is different from reality.
Therefore, VR can affect people's hand-eye coordination. It takes a while for you to enter the VR to adapt to its interaction from the real world. It also takes a while to get out of VR and adapt to the real world.
For example, I often play vive for two hours, then I feel like my hand is not my own, and I just want to find something to wield and click. This is the effect of VR on me.
But because I am an adult, this influence may only be restored to me in a matter of minutes. The child's hand-eye coordination system is in the development stage. From the “controller interaction system†in VR to “the hand-eye coordination system in realityâ€, it may take longer to break out.
For example, when you just picked off the HMD, a friend lost a ball to you and you reached out to pick it up... Hey, you didn't catch it!
Therefore, after VR can not cut vegetables, but also can not operate on the patient.
Impact on the balance system
Loss of balance
The experience after taking off VR is similar to what you get from a boat or plane.
For example, if you play for a while, a bad cardboard is equivalent to going ashore from a very swaying boat - it's more than a halo.
And if you play HTC vive for a while, it's the equivalent of walking from the first class of an advanced aircraft - slightly uncomfortable.
In general, however, the symptoms of disembarking and disembarking caused by VR will last for a period of time that varies from person to person.
So oculus and PSVR encourage the player to sit on the swivel chair and it is not easy to fall than standing and playing.
As the saying goes: "VR does not drive, driving does not VR." After the VR is on the surface, you cannot drive it immediately, even if it is a bicycle.
Damage to multi-tasking ability
Motion stick
Disorientation: Similar to the way you sit on a swivel chair and turn a lot quickly, and then suddenly stand up and walk out, and you're lost.
Nausea
Involuntary movements: For example, children who suffer from ADHD are often chaotic.
Second, the head
Dizziness
Temporary syncope (blackout)
Third, the eyes
In fact, I have a better understanding of glasses, I know that every time I wear glasses to the center of the lens is the thinnest point of the visual center, so when wearing a HMD patiently adjusted the interpupillary distance to 68mm, the upper and lower position just to be aligned Starting to play, many people do not pay attention to wear, so it may cause vision problems. The result is that you want to see a clear, single picture.
However, VR's damage to the eyes is mainly due to accommodation-vergence conflict, so it is equivalent to staring at a relatively close screen, and the symptoms are:
Eye strain: Actually, when office workers stare at computer screens for too long, they will do the same.
Eye muscle twitching
In addition, the current HMD cannot be played for children under the age of 13, mainly because the HMD is larger than the child's head, and the "big" will cause discomfort, such as the lack of interpupillary distance and so on.
Excessive sweating causes excessive steam on the lenses of the HMD and blurs the image in front of the eyes.
Fourth, the visual system
Of course, the most influential epileptic seizures. Almost anyone with a history of epilepsy cannot play VR at all. However, only one person out of 4,000 is epilepsy.
What is exaggerated in VR is Photosensitive Seizures.
Some of our materials in VR are High spatial frequency imagery, such as:
Fine textures
Or stripes
In VR you turn your head, because of the "low-resolution instant rendering", you will see the stripes in the flicker (similar to you rolling these delicate stripes on your phone or computer, but stronger than this ~ )
Therefore, this is the reason why current VR games rarely use some low polychromatic monochromatic color patches because they rarely have some patterned materials.
In addition, if one of the eyes is unable to obtain vision through correction, that is, people who normally use only one eye to see things, they may not be able to enjoy the benefits of VR.
The same, double vision person cannot play VR either:
Fifth, hearing damage (hearing damage)
In reality, even if we work with computers, we don't always listen to music. In VR, we have to have sound all the time, so it may cause hearing damage, and in particular, we will inadvertently make the sound louder in pursuit of immersion ( Especially in an environment where our country is particularly noisy everywhere.)
And this damage is irreversible!!!
Physical accidents
The other is the injury problem when playing VR, which is related to the playing environment:
For example, there can be no things (even people or pets) within a safe range, otherwise it is easy to wave.
Some people even forgot that they were in VR, so they ran so violently that they hit a piece of furniture or a wall and were injured. . For example, your leg hits a very sharp corner of the table and hits the leg with a purple hit.
There is also a more devastating injury, that is, to take the stool in VR as a real stool, and then sit up and fall to the ground.
Seven, the impact of the value of
Eight, psychological
Claustrophobia
Dark fear
The fear of nothingness and nothingness
High-intensity terror
Fear of spiders, snakes and other creatures
Finally, after a few pictures of the “town of rain†in the town, the FBI males took off the AR glasses:
At present, there are indeed some potential negative effects of using VR devices, but the most important thing is that we should be cautious. 87 Jun believes that users should control their own time to play VR devices, and pay attention to the psychological problems that VR may bring.
Solar cable is a kind of cable specially used for solar power generation system. It has the characteristics of high temperature resistance, ultraviolet resistance, corrosion resistance, etc., and can run stably in harsh outdoor environments for a long time. Solar cables can not only effectively transmit the electricity generated by the solar power generation system, but also provide a safe and reliable power connection.
The solar cable is made of high-quality conductor materials and insulation materials to ensure the efficiency and stability of power transmission. It has low resistance and voltage drop, which can minimize energy loss and improve the efficiency of solar power generation systems. At the same time, the solar cable also has good wear resistance, can withstand a variety of harsh climate and environmental conditions, to ensure the long-term stable operation of the system.
The solar cable also has the characteristics of fire, flame retardant, anti-aging, etc., which can effectively improve the safety and reliability of the solar power generation system. It is made of special materials that can withstand high temperatures and fire, reducing potential fire risks. At the same time, the solar cable also has a long service life, can withstand a long time of use and frequent movement, not easy to aging and damage.
Solar cables are widely used in all aspects of solar power generation systems, such as the connection between solar panels and inverters, and the connection between inverters and power grids. It can not only meet the requirements of solar power generation system for power transmission, but also ensure the safety and stability of the system. Solar cable is an indispensable and important part of solar power generation system, which provides reliable support for the efficient operation of solar power generation system.
In short, solar cable is a kind of cable with high efficiency transmission, high temperature resistance, ultraviolet resistance, corrosion resistance and other characteristics, which can provide a safe and reliable power connection for solar power generation system. Its application can improve the efficiency, safety and reliability of solar power generation systems, and make important contributions to the development of sustainable energy.
