Some people say that VR helmets will be dizzy? Vomiting? Uncomfortable...
So, is such a VR head-display device suitable for small children to try?
The day before yesterday, HTC Vive's public relations pushed a press release to the media with a long title. The experimental summary report on the impact of the first long-term use of VR head-mounted display devices on low-age users' vision was officially released for future VR technology. The foundation of application popularization.
Regarding this experiment, the article introduces that 50 Beijing-based pupils from 9-12 years old have been recruited from the VR campus popularization experience by the Beijing Future Image Innovation Center and Beijing Institute of Technology. Experiments were conducted to investigate the effects of long-term use of VR head-mounted display devices on the visual acuity of users of lower ages."
The content of the article has two important conclusions:
1. Experiments have found that low-age users use VR head-mounted display devices and use tablet devices to have similar effects on vision. In some specific cases, using VR has even more positive effects.
2, the researchers believe that if the virtual image distance design is reasonable, high-performance VR equipment with the same level or higher than Vive can play a better role in correcting vision, and it is likely to become an important means of correcting vision in the future.
At the end of the report, the researchers believe that the HTC Vive can be used by children over 10 years of age when the device is properly worn and the content is appropriate.
Then the question is coming, is this report objective?
Is the negative impact of VR on the eyes really smaller than that of tablets and mobile phones?
Take myopia, and staring at nearby objects for too long may cause myopia (this view is controversial but widely accepted). So is VR not staring at the screen very close? You might think like this, but that's not the case.
Although the VR screen is very close to the eye, the VR lens design actually distort the light, so that the virtual image is projected not in front of you, but at a certain distance, even infinity. Need to know that our eyes are not focused on the screen, but on a virtual screen with a certain distance. So myopia is not a problem.
Let's look at the smart phone again. Many people take the phone very close to the eyes and play for a long time. VR head display does not have this problem.
So, on the one hand, from my humble point of view, I don't think that the VR head shows more damage to the human eye than a smartphone, for four reasons:
1) The overall brightness is low;
2) People generally don't stare at a place in VR. In contrast, playing a smartphone will be;
3) The human eye is actually focused on a virtual image with a certain distance;
4) VR content is usually not long.
On the other hand, I also look forward to research on the side effects of blue light damage and lens distortion. However, at present, their impact is not large, nor permanent. It is not so easy to improve through screen or lens design.
So, is VR suitable for children to play?
Even if the negative impact of VR heads on the human eye may not be as big as a mobile phone, the real long-term effects are unproven after all, and we should be cautious about children.
This experimental report concluded that HTC Vive can be safely used by children over 10 years of age. How reasonable is this?
Let's take a look at the recommendations of the three major heads on the age of use. According to Digital Trends, their age restrictions are:
The age recommendation for the Oculus Rift and Samsung Gear VR heads is 13+;
Sony PlayStaTIon VR is not recommended for people under the age of 12;
Although HTC Vive did not give a specific age limit, it also warned against the use of Vive for children. (Lei Feng has asked the Vive official about the relevant policies, and has not yet responded)
The picture above shows the part of the Oculus official Health and Safety Warning document on children. As written above, this product should not be used by children under the age of 13. For users over the age of 13, avoid long-term use, as it may affect the coordination, balance, and multitasking capabilities of the opponent. In the event of these symptoms, parents should be closely monitored by the user to limit the time they spend using the product and to ensure that they are separated during the period of use.
It should be pointed out that Oculus does not mention the negative effects on the eyes, but many other symptoms that may be caused by the VR experience. The safety of children's use naturally takes these factors into consideration.
It is also important to point out that this is not based on policies that have been proven to be harmful to children, but more of a cautious decision. After all, VR is a new thing, we still don't know what its long-term impact is.
In addition, the three major leaders made such guidance, and some may also be because the head display is not specifically optimized for children, and the weight, volume, and distance adjustment may not be suitable for children.
There are also doubts about the age limit given by the head display manufacturers. According to Inverse, psychologist David Schwebel from Alabama State University said, “I don’t think age restrictions are necessary. Children of all ages like all kinds of fictional content, including movies and books.†But he Two reservations are also given. First, the content should be graded according to age, just like movies and games are doing; second, the extent to which long-term use of VR has a psychological impact is still unknown.
Another expert, MarTIn Banks, professor of optics, visual science, psychology and brain science at the University of California at Berkeley, told Digital Trends, "So far I have not seen solid evidence that children of certain ages wear VR. Head of the head will have a negative impact. My judgment is that they (the manufacturer) may feel that the child is still in the stage of growth and development, and the growth becomes slower after entering adulthood. Therefore, it is best to keep the child still in the stage of rapid growth. Be cautious, so I decided to advise people not to let children use it as well."
In addition to seeing their views, we also need to know that these two experts are not the stakeholders of the manufacturers. US policy stipulates that any content that accepts sponsorship needs to be clearly marked.
Finally, the symptoms of vertigo are already determined to affect some people and regardless of age, so if you feel dizzy, it is best for adult children not to play.
