Description

technical field [0001] The invention relates to a measuring device for measuring the reaction time of a human body to external stimuli. Background technique [0002] Due to the great flexibility of the computer, in scientific research, the computer is widely used to generate and control the measurement of the reaction time of various stimuli in the human body. Ordinary computer keyboards and mice can be used to measure the response delay of experimental subjects to stimuli, that is, the time from perceiving the stimulus to responding. However, the measured time is the time when the computer program detects the keyboard and mouse events, not the time when the subjects press the keyboard and mouse. However, current operating systems, such as Windows, MAC, Linux, etc., are multi-tasking operating systems, and the delay between the subject and the detection depends on many factors, including the mechanical characteristics of the keyboard and mouse and the delay caused by deboun...
