McAdams On: The HD-to-3DTV Transition
Getting the "vergence" right for the display size should be a very solvable problem, at least for "R" rated movies. Young children have smaller interpupillary distances than adults, so what works for their parents may be uncomfortable for them.
Walking around in real life, we always focus and converge our eyes on the same point. 3D requires us to focus on the screen, but converge our eyes where the illusion belongs. This unusual use of our eye muscles is a skill that can be developed and improved with practice, like an athletic skill. So, an effect that may be thrilling to experienced 3D viewers could be overwhelming to beginners. If 3DTV does become universal, the whole population may some day be much better at this than we are now.
