What is Reaction Time?
Reaction time is the measure of how quickly an organism responds to a stimulus. In the digital age, this Human Benchmark is crucial for competitive gaming (eSports), driving safety, and overall cognitive health assessment.
Our tool uses a high-precision millisecond timer to calculate the gap between the screen color change (stimulus) and your mouse click (response). The average human reaction time is approximately 273 milliseconds.
How to Improve?
- Consistent Setup: Use a wired mouse and a high-refresh-rate monitor to reduce input lag.
- Focus & State: Mental fatigue and caffeine levels can fluctuate your results by up to 50ms.
Reaction Test FAQ
Is 200ms fast?
Yes, 200ms is considered significantly faster than the average human response time.
Does hardware matter?
Absolutely. Wireless peripherals and slow monitor panels can add 20-50ms of "artificial" lag.
Why am I slow today?
Sleep deprivation and stress are the primary biological factors that slow down neural paths.
