Researchers from the universities of M lwa nchen and Salzburg have shown that the viewing of 3d content on a tv is no increased risk of seizures with brings. To the investigation, 140 children.
The study was conducted because there is still no study was published about the effect of the viewing of 3d content by children with epilepsy or an increased risk thereof. At the same time, suggest various media the existence of such a link.
In total, 140 young patients with an average age of 12 years, first a standard test for photosensitivity subject, followed by the viewing of 3d content for 15 minutes. Through an EEG, the effects of the two incentives is mapped and compared by two independent specialists. For the 3d tests was a 50″-3d plasma tv and the children were at a distance of about two meters in front of the tv.
According to the researchers, the EEC of the trial the participating young people increased seizure activity during the running time of the 3d content. Although there are no children without increased risk of participating in the study, the researchers conclude that people with as yet no diagnosis for epilepsy is also no increased risk of seizures when watching 3d content on a 3dtv.
However, showed 20 percent of the patients other symptoms, such as dizziness, headache and nausea during the examination. This happened both when viewing 2d when viewing 3d content. According to the researchers, are seizures independently of the 3d, but they have to do with the kind of content that is shown, where things like color, contrast, flicker and patterns in more of a role to play.
There is something to things at the research. So is the number of subjects is relatively low, there was no control group of children without epilepsy, and is only made use of a 3d-plasma tv with active 3d glasses. It was more been to 3d tvs based on lcd technology, with both active and passive 3d glasses.
