CONTROLS & BLUEPRINT SPECIFICATIONS

🕹ī¸ CONTROL SCHEMAS

  • TAP / CLICK
    Click your mouse or tap anywhere inside the active reaction pad when it flashes **Green**. Works on both touchscreen devices and desktop cursors.
  • PVP SPLIT-SCREEN
    Each player claims half of the screen. Wait for the green flash; the player who taps their side first gets the point. Early clicks award points to the opponent!
  • ASMR AUDIO CUSTOM
    Enable/disable sounds or select click themes (Cherry Blue, Cherry Red, Cherry Brown, Synth Beep) to receive instant auditory feedback when you press or click.

⚙ī¸ SYSTEM CABINET SPECS

Objective:React as fast as humanly possible to the green light.
Trial Sequence:Complete 5 trials to lock in your final averaged latency in milliseconds.
Anticipation Guard:Clicking early triggers "Too Soon!" and invalidates the current trial to prevent cheating.
Esports Rankings:Compare average speeds against standard mouse/hardware latency offsets.

Overview & Capabilities

Measure your neural visual reaction time with millisecond precision using our Human Benchmark reaction test! Wait for the red screen to turn green, click as fast as possible, and calculate your average reaction speed across 5 test rounds. Learn how your cognitive reflexes compare against the global human average (~250ms) with full distribution charts.

Tutorial

How to Use

01
Click the large red screen area to arm the reaction test.
02
Wait patiently while the screen displays 'Wait for Green...' (randomized delay between 1.5 and 5 seconds).
03
The instant the screen flashes vibrant Green, click or tap immediately!
04
Review your reaction time displayed in milliseconds (ms). Clicking prematurely on red triggers a false-start warning.
05
Complete 5 successive rounds to calculate your official average benchmark score.
Capabilities

Key Features

Sub-Millisecond Precision Clock: Utilizes the High-Resolution Time API (performance.now()) for microsecond accuracy.
Randomized Anti-Anticipation Delays: Randomized 1.5s to 5s trigger intervals eliminate rhythmic guessing.
5-Round Benchmark Average: Smooths out outlier clicks to provide an authentic cognitive reflex metric.
Global Benchmark Distribution: Compares your average against human norms (Top 1% < 150ms, Average ~250ms).
Zero Input Latency Canvas: Direct DOM hardware event listeners bypass standard browser rendering delays.

Tips & Best Practices

💡
Keep your finger or mouse button slightly pressed to reduce the mechanical distance of your click.
💡
Minimize system/display lag by using a high refresh rate monitor (120Hz+) if possible.
💡
Don't try to predict the flash; anticipate the change rather than clicking randomly.
💡
Try the local 2-Player mode to test your reflexes against a friend in real-time.

Answers

Frequently Asked Questions

Q What is the average human visual reaction time?

The average human visual reaction time is approximately 250 milliseconds (0.25 seconds). Elite esports athletes and professional racers often achieve reaction times between 150ms and 190ms.

Q Why does the test require 5 rounds to calculate an average?

A single click can be influenced by accidental anticipation or momentary distraction. Averaging 5 trials filters out statistical anomalies to give a reliable measure of your true cognitive processing speed.

Q How does monitor refresh rate (Hz) affect reaction time scores?

Standard 60Hz monitors refresh every 16.6ms, while 144Hz monitors refresh every 6.9ms. Higher refresh rates display the green stimulus slightly sooner, which can improve measured scores by 5-10ms.
