Frame per second (FPS, also known as frame rate per second) is a unit that describes the playback of images in games, movies, and animations within one second. The speed at which the brain processes visual information is called “image resolution per second.” ” (images per second), affects how quickly we respond to changes in the environment, also known as dynamic vision.
Dynamic vision has varied from person to person since ancient times. A recent study has strengthened this argument. Some people are born with a “Sharingan”, see the world with a higher FPS, and have more advantages in high-speed activities or competitive game performance. . The report was published on the Scientific Journal Network “PLOS ONE。
Past research has shown that animals with highly dynamic vision are mostly species with a fast pace of life (especially predators). For example, the peregrine falcon can see 100 frames per second. This ability will decrease with age, and will increase under severe stress. There is a temporary decrease following exercise, but no one knows the difference between humans of the same age.
Clinton Haarlem, a doctoral student at Trinity College Dublin, and his team designed an experiment to place LED lights and electronic devices in an opaque black box, and install a viewing tube on top with a black Frame goggles that use human perception of flickering lights to measure dynamic vision.
The study recruited 88 healthy subjects, regardless of gender, with normal (or corrected) vision between 18 and 35 years old. It was found that some people recognized that when the light was on, the device was actually flashing at a frequency of 35 times per second. People can find that the device is flashing at a frequency of 60 times per second.
Clinton Haarlem is atThe British “Guardian” reportsThe research team believes that the brains of subjects who can see high-speed flashes will receive more visual information in a fixed period of time than those who cannot see clearly.
The research results show that there is little difference in dynamic vision between men and women, and the visual perception speed of each person changes relatively little in multiple experiments conducted at the same time.
Kevin Mitchell, associate professor of neurobiology and co-author of the paper who supervised the research, said that because the average person can only understand the world through subjective experience, they may naively believe that other people see the world in the same way as themselves. “The research results show such differences, Some people do see the world faster than others.”
Although there are still many unknown factors that affect this perception, Clinton Haarlem suspects that the image resolution per second of elite athletes and professional e-sports players may be higher than that of ordinary people. Individual differences in perception speed may be necessary when positioning or tracking high-speed movement. objects become apparent (e.g., ball games), or when the visual scene changes rapidly (e.g., competitive video games).
“Perhaps they (people with high dynamic vision) have an advantage over others even before they pick up a racquet to play tennis, or pick up a controller to enter some online fantasy world.”
Although people’s reaction speed can be improved through practice, dynamic vision is related to the reaction time of the brain to process visual information. It is innate or can be made perfect through training. It is still in unknown territory, Clinton Haarlem said, ” “We don’t know enough regarding this kind of change at this stage, and it may be related to our eyes, or it may be related to the brain filtering information.”
