⚙️ How Error-Blocking Works
The Science Behind Kinetic Memory
Lexicon uses a technique called error-blocking to build permanent muscle memory:
Detection
When you press a key, the system compares it to the expected character
Blocking
If wrong, the input is blocked and you see a visual shake effect
Correction
You must find and press the correct key to proceed
Learning
Your brain encodes the correct tactile pattern
Why This Works Better
Traditional typing tests allow you to make mistakes and backspace. While this measures speed, it actually teaches your fingers the wrong movements. Error-blocking forces you to learn the correct pattern from the start.

📊 Understanding Your Statistics
WPM (Words Per Minute)
Standard metric calculated as: (characters typed / 5) / time in minutes
5 characters = 1 "word" in typing metrics.
Accuracy
Percentage of correct keystrokes: (correct / total) × 100
In error-blocking mode, this shows how many attempts you made vs. term length.
Mistakes
Count of incorrect key presses that were blocked.
Lower is better - shows your muscle memory is improving.
✨ Best Practices
🎯 Focus on Accuracy First
Speed will come naturally as your muscle memory develops. Don't rush.
🔄 Practice Regularly
Short daily sessions (10-15 minutes) are more effective than occasional long sessions.
👁️ Look at the Screen
Don't look at your keyboard - train your fingers to find keys by feel.
⌨️ Proper Posture
Sit upright, wrists straight, fingers on home row. Good posture prevents fatigue.
📖 Read the Definitions
After completing a term, read its meaning and usage. This reinforces learning.
🎵 Find Your Rhythm
Typing is about rhythm. Focus on smooth, consistent keystrokes.
