VR technology is currently a popular technology, and various industries are using it for research, expecting it to bring more development and future. However, studies have shown that VR technology may harm children's health, and we do not know the long-term effects of children on VR.
VR has become the focus of many technology companies. In people's imagination, VR is a dominant technology, whether it is home or business, and will become the main way people interact with computers. However, according to a report on the Guardian website, a study by the University of Leeds in the UK shows that VR devices can cause some harm to users, especially children.
The study was led by human performance technologist Faisal Mushaq. Researchers at the University of Leeds collaborated with VR in the UK to select 20 children between the ages of eight and twelve. First of all, these children played a 20-minute VR game, completely immersed in the virtual world. The researchers then tested the children. “In VR devices, the virtual 3D world is displayed on a 2D screen, which puts pressure on the human visual system,†said Mark Mon-Williams, a professor of cognitive psychology at the University of Leeds. “For adults, this can cause headaches and Eye fatigue, and for children, we don't know the long-term effects of VR."
Through testing, the researchers found that the child's vision did not show a serious decline. However, in both cases, the child's stereo sharpness (the ability to feel the distance) was affected, and after playing the VR game, the balance of a child became very bad. Although these effects are short-term, they can be clearly observed. “This study is the first to examine the impact of VR on children's vision and balance,†Mushtaq said. “VR offers a variety of exciting possibilities, but if we want to ensure that children benefit from it, we must establish scientific evidence. To ensure the safe use of VR."
Today, many companies have begun to produce VR games and apps; some filmmakers have explored VR's potential in documentaries and cartoons. VR applications have also expanded into education. At the University of Leeds, students in the Department of Medicine began to observe teeth in VR, or to study tumors and wounds. VR has a wide range of prospects, but if it hurts users, its usage scenarios must be greatly limited.
“You can wear a VR helmet and participate in a bicycle race – the exercise bike is equipped with some equipment to test your effort,†Mon-Williams said. “You can practice tennis or golf in VR. In the farther In the future, we can replace the computer terminal with a VR helmet. The keyboard and mouse will become history. We can wave our hands and put words into sentences. Just like in the movie Minority Report, the role played by Tom Cruise is directly manipulated. The symbol on the screen."
However, the expansion of the VR space should not be just a faster computer, a better screen, but also the use of children. “We need to understand how children interact with the virtual world: how they focus on items and how to understand the distance in the virtual world. The key is that we should deal with these issues now and design VR devices that don't cause visual or balance problems. â€
"The good thing about VR is that you are no longer subject to Newtonian mechanics. You can create your own world, but it can also lead to some unnatural interactions. The solution to the problems we find may be very simple. But anyway, in In the future, the way we look at things will change dramatically. We need to make sure that VR applications have a right start, and the VR industry should take this type of research very seriously."
