According to Mark Pesce, a research specialist in the field of virtual reality technology, TV 3D could cause a negative impact on the health of watchers. TV makers do not agree with the comment of Mark Pesce, but the fact they still have to warn buyers about some errors likely to occur while using the 3D feature.
Pesce says, a website of Samsung in Australia offered a series of warnings about the direct effects such as disorientation, headache, fatigue and advised users not to watch TV 3D if the body were in not functional status, sleep deprivation or exposure to alcohol medium. Even in the manual use of TV 3D Series 7 from Samsung also showed not to let children under six years old view any 3D image. However, these warnings are only available in Samsung’s TV 3D. According to Pesce, 3D is not suitable for health. Samsung warned that people should limit viewing World Cup 3D in the public bars.
A report showed that 15% of the audience after watching 3D movies felt headaches caused because the content made viewers’ eyes move in more directions. Also, it also made the area on the screen dimmed, causing you to lose focus on the outer parts and let the main body feel more close to viewers.
With the 3D films, he said, “viewers after leaving the cinema 3D, the perception of depth in their vision will be disordered. It will return to its original state, but not immediately. Depth perception in some people will back away, while others take an hour or more.” A 3D film will make viewers feel as if they were moving everywhere like real life, caused by the vestibular system in humans. But the reality is you never walk away, but only stare at the screen. And the interruptions during the presentation will make some people fall into a state of fatigue.”
Even if the 3D system can be useful, it is still just a machine helping bring psychedelic. The eyes of viewers again have been fooled by the floating 3D images on a 2D screen, and after aware of the frame, the brain and the eyes will return to a healthy state.
Rejecting the warnings given, the Korean manufacturer said that there was nothing to worry about TV 3D at all. A spokesperson of Samsung said, “TV 3D Samsung is very safe. If used in the right way and follow the instructions, 3D features will not be harmful to health and make viewers feel tired.”
Director of the research center Samsung R & D, Simon Lee, added the ability to recognize the three-dimensional effect of each person was different, about 2% of viewers can not see the 3D effect clearly, and children are also in that group. These people should not access to 3D.
According to Tech Radar, 3D technology and the 3D existing products cannot satisfy everyone, and unfortunately, they are still too new to anyone who can understand. The impacts and effects of 3D still need time to verify.
