A Study on the Relationship Between Refresh-Rate of Display and Reaction Time of eSports

In Electric Sports (eSports) filed, High frequency displays such as 144 Hz and 240 Hz are more often used than 60 Hz display. In addition, it is said that people who use a high performance computer with graphics board are ahead of the eSports. Therefore, we have been studying the relationship between the performance of computers and reaction time of eSports. As a preliminary test, we conducted a simple reaction time test in which a button was clicked when the screen color changed. As the result, differences between 60 Hz, 120 Hz and 240 Hz cannot be ignored. It is assumed that the reaction time of each individual is constant, so this difference may be due to refresh-rate. This is because, the time of presenting light stimulus is different between each refresh-rate. Therefore, it has been suggested that using a display with high refresh-rate when competing in such as a simple game is advantageous.
