3D movies are causing headache
Even if technology is now better, some people are still suffering from headache when watching 3D content
3D has been in the history of cinema since the very beginning, already in the end of the XIX century. It evolved as Polaroid invented the red-green glasses, and directors as Hitchcock and actors as Vincent Price used the 3D system in their movies. The 3D is now very popular: there are about 400 movies filmed in 3D, and about 5000 theatres equipped with 3D projectors. The estimated amount of cinema theatres in the world is 43000, so 3D movies can be enjoyed in an approximately 12% of the theatres worldwide.
However, watching 3D movies and 3D pictures with the glasses can be an unpleasant experience for some people. When watching 3D content, our eyes are forced to do unnatural movements and that causes not only huge headaches, but also nauseas and eyestrain. And there are issues that 3D technology cannot face: stereoblind people (5-8% of the population) and people suffering from other vision deficits (20-30% of the population) will experience the same problems when going to the 3D shows.
The trend is a rising in 3D movies production, as many cinemas want to offer an added value for their customers, something that we cannot find at home watching the movie in DVD. So it seems obvious that if the content in 3D increases, the problem related to 3D effects increases as well.
Research question: Is there any solution to see 3D movies for these people?
