Stereoscopic 3D movies have become much more popular within the cinema market, with many theatres and films offering it as part of their regular lineup. But for all the growth the technology has had in traditional movie theatres, it has lagged severely in the home consumer electronics department. This cannot be directly attributed to the lack of content and accessibility, as many modern TVs and content providers accommodate stereoscopic 3D. Generally, the blame is placed on the glasses that are required to be worn to produce the 3D effect. They are considered to be too much of an inconvenience for the viewer compared to the service they provide. In order to promote further consumer adoption, a 3D technology that does not utilize glasses is necessary, but must still maintain comparable levels of availability.
