Imagine yourself sitting and playing a shooting game, racing simulation or near the TV or monitor for about an hour. The camera shakes and constantly wanders the scene, while the effects of light change every hour. If you are feeling sick, sweating, vomiting sensation, headaches - something that would normally happen on long drives or on a roller coaster.
Don’t be alarmed or call an ambulance: games can really be blamed for causing an effect that affects vision, the brain and balance. And, believe it or not, this is a passing effect that affects many more people than you think.
What is the diagnosis, doctor?
It's called motion sickness. This is a "bug" in our vestibular system, which has nothing to do with the evidence to go to college. It is formed by the organs within the inner ear responsible for balance. In this space, the semicircular canals are bone tubes that are filled with fluid, the endolymph.
When you make a move, the endolymph moves in the opposite direction, something that creates a chain reaction that reaches the central nervous system, "warning" that your body is not stopped.
If you're in a car (ie, stopped, but within a moving structure), endorphin does not send stimuli, but your body is shifting and your eyes confirm it, which gives a knot in his senses. Moreover, the brain perceives the discrepancy and concludes that there is something wrong, as the occurrence of poisoning or hallucination, and tries to solve the case to eliminate potential toxins from the body - hence the feeling of vomiting and nausea.
What my game has to do with it?
The scenario created by a game, especially in the first person, try to simulate exactly something that would be captured by the eye and processed by the brain. The problem is in the game, you make frantic moves sideways with the camera runs at high speeds and jumps unimaginable heights - while the reality is that you are practically immobile.
But it is not all that is at stake. The frame rate shown per second also greatly influences. A game at 60 frames per second (fps) seems more dynamic, fluid, higher quality graphically - not "slow motion" or traces of objects that move on the screen, something common when the rate falls or is naturally low.
The problem is that the speed increase contributes to motion sickness, since everything is too fast, and your brain was not used to all this. When he's too slow, it is also a problem, since no change in the normal agility (or in this case, lack thereof).
Blur
The effect of motion blur, which causes blurring and simulates the fast moving objects, can also contribute to motion sickness. This is because monitors with low refresh rate take up to a very fast moving process, leaving smudges on the screen and letting your brain even more confused.
A monitor with a rate of 1 millisecond and update (refresh rate) of 60 Hz is considered common, but higher rates can also be the solution - in addition to further increase their experience and precision shooters, for example.
FoV
The problem may also be in the field of view (field of view, or FoV). When this value is too small, the edges of the scene details appear less on the screen and you get the feeling of claustrophobia that aggravates motion sickness.
Games as Titanfall bring satisfactory camera angles and a field of view as open as possible, to avoid this kind of effect. This indicates that the developer knows the problem and seek to ameliorate it in newer titles.
And then have a cure?
There is no miraculous way to end an effect of an hour the brain to another. But that does not mean that some care may be taken to at least reduce the effect of this problem and be able to play for longer and at peace with the body.
Check out some tips:
- Adjust field of view in the graphics options of the game to make it wider (90 is a good value);
- Search for a monitor of at least 60 Hz;
- Play the games in greater quantities that cause dizziness to "train" the brain, but with intervals of rest after about half an hour;
- Leave a light on while you play, even if it is a weak source pointed to the ceiling;
- Consume a regular amount and healthy foods before and during the gambling;
- Place a black dot in the center of the TV, even if it is a piece of painted paper to create a reference point for the brain;
- There are drugs that fight nausea caused by motion, but avoid unnecessary medications and always consult a physician first.
