And not surprising. But in any event, let's not forget what the motion
sickness constraint is used to provide a practical minimum viewing distance,
e.g. expressed in terms of screen heights, in order to get an idea of whether
or not 4K makes sense for home use.
Viewing distance has nothing to do with motion sickness Bert. Please stop
trying to push this false canard.
Motion sickness from any kind of screen is the result of fooling the human
visual system, in a manner that creates the illusion of fast motion. It is
related to the way the brain reacts to this stimulus; the impact varies
considerably across the population.
If a content produced WANTS to make people sick they can provide this type f
stimulus. This is very rare, as people who create content for theaters and
other big screen environments work very hard to avoid this.
Anyone who argues that 4K is "not needed," and then at the same time tries to
argue that there's no motion sickness problem, is arguing against himself.
Because quite clearly, if there is no practical minimum viewing distance
constraint, 4K may even be inadequate. You might be arguing that 8K, or more,
is needed.
This is absurd. We are simply trying to emulate the real world Bert.
People typically do not get sick looking at the real world. They get sick from
motion that upsets their equilibrium - rinding in a car or on a boat, or an
amusement park ride.
Are you now arguing that we need more resolution to make people sick?
The rest deleted as it is based on garbage, not science.
