They've been passing out 3D glasses in movie theaters for decades. But things are changing, and they're changing with the help of video games.
While 3D entertainment keeps getting bigger and bigger, movie director James Cameron says the technology owes much of its continued growth to games. In speaking to Yahoo , the "Avatar" director (who is currently working on the sequel), says 3D gaming is the "entry level for most people."
"Video games are going to help propel the autostereoscopic (glasses-free) play because that's going to be the entry level for most people. These single-viewing devices that are engaging the person to play these video games will drive a lot of investment in autostereoscopic displays for that very reason."
That sounds like he's referring to the Nintendo 3DS, but don't forget that Avatar: The Game was one of the very first 3D offerings in the interactive entertainment world, and you can probably expect the same thing when "Avatar 2: The Game" arrives. But will all this home 3D entertainment eventually erase the glasses from theaters? Cameron doesn't think so:
"I don't think we'll ever get rid of the glasses in movie theaters. Not in my lifetime, anyway, but we're going to get rid of them at home because it's a different viewing model type. You're doing other things. You're pausing a game or a movie and going to get pizza or whatever it is. It's not the same very-dedicated sort of consciousness that you have in a movie theater, so getting rid of the glasses will be a big deal."
Some say they're waiting for the time when they'll be able to indulge in 3D without the glasses. Others maintain that such viewing (glasses or no) can cause relatively serious health issues; many have complained of headaches and vision issues. But regardless, it's a technology that will continue to press forward.
