Professor Hideo Miyaji (Department of Information Systems, Faculty of Media and Information Sciences), Tokyo City University, has revealed through experiments that the human eye can recognize changes of at least about 1000/8 seconds (8 milliseconds).
In recent years, "e-sports" (electronic sports), which compete for physical and intellectual abilities using computer games, have become popular.The sport can be played between young people and the elderly who have different physical strengths, but the reflexes weaken with age, so a certain amount of handicap is required for young people to maintain fairness.In addition, high-performance computer systems are said to be effective in the game, but there are not many scientifically shown examples.
In this research, we have independently developed a PC game that measures the simple reaction time, "press the button when the monitor color changes from white to blue."For the monitor, we used the highest performance commercial PC monitor whose image changes every 1000/4 seconds (operating frequency 240Hz) (60Hz for daily use monitors).
Professor Miyaji and a total of six students measured their judgment ability (simple reaction speed) by pressing a button at the moment when the image on the monitor changed. We experimented 6 times at 240Hz and 120Hz, respectively, and found the delay in the average time to press the button.As a result, it was found that the reaction speed became faster at 30 Hz, and at least the human eye recognized an image change of 240/1000 seconds.
Therefore, it is possible to easily set the handicap between athletes of different ages by changing the frequency of the monitor.In addition, although this experiment was centered on young students, it is thought that it is possible to improve judgment ability by e-sports, which changes images at high speed even as the age increases.In the future, it is planned to clarify the skills that only experienced people have, and to show that e-sports enhances human skills and is also effective for health.
