Scientists will be able to identify the scene of 3D-films, causing headaches – 3DNews

A team of researchers from the Moscow State University named after MV Lomonosov Moscow State University (Moscow State University) has been studying the problem of headache that occurs after viewing of 3D-films.

Surveys show that only a third of viewers watching stereoscopic films without experiencing any problems. Approximately 27% of people feel “some discomfort”, 22% complain about the deterioration of health, 7% experienced a severe headache.

Scientists say that a headache is a brain response to the “wrong” image, at the same time coming in both eyes. The brain must combine them to get the stereo, but to do this, unfortunately, does not always work. The viewer gets used in most cases, these “wrong”, without noticing it, but, as the statistics show, this is not always the case.

The research team calls for more than fifteen reasons described problems. They are divided into two categories – equipment deficiencies and shortcomings of the film. The first category is explained, first of all, the natural tendency of owners to reduce costs, which inevitably leads to a decrease in quality stereopokazov. Bad points, cheap projectors and other equipment of inadequate quality drastically reduce the quality of the film itself. The reasons for the second category are more complex, diverse and yet, unfortunately, are not always available to fix or avoid. Among them, the most painful for the audience “Puncture.” – Mistaking the left and right video signals, it sometimes happens during installation even professionally films made

Russian scientists have created a so-called “metric” – a software product that allows you to keep track of the problem of 3D-films while minimizing time, technical quality control. Using this metric, the research team scanned almost all video products, manufactured in the Blue-ray discs, and has made statistics problems. Total using metrics 105 stereo CDs, with 23 films 65 problematic scenes was found was analyzed.

« This means that when buying a 3D-movie on Blu-ray disc you with probability 21% buy the film, which will have at least one scene with the problem of tangled angles. If you want high-quality 3D now, choose high-budget movies and rooms with expensive equipment », – say the authors of the work.
