Speed Reader

A web application for speed reading using RSVP (Rapid Serial Visual Presentation) technique.

What is RSVP?

RSVP displays text one word at a time at a fixed location on screen. This eliminates eye movement (saccades) between words, allowing you to read faster. The red letter marks the "Optimal Recognition Point" (ORP) - the point in each word where your eye naturally focuses.

Features

• File Upload: Upload any .txt or .md file to read
• RSVP Display: Words displayed one at a time with centered ORP
• Adjustable Speed: Control reading speed from 100-1000 WPM (words per minute)
• Playback Controls: Play/pause and restart functionality
• Progress Tracking: Visual progress bar shows reading position

How to Use

1. Open the application in your browser
2. Drag and drop a text file or click to select
3. The words will display one at a time
4. The red letter stays centered - this is the ORP
5. Use +/- buttons or preset buttons to adjust WPM speed
6. Click pause to pause, restart to begin again
7. Click Back to upload a different file

Technical Details

• Built with React + TypeScript + Tailwind CSS v4
• Vite for development and building
• The ORP is calculated based on word length:
  • 1-3 letters: first letter
  • 4-5 letters: second letter
  • 6-9 letters: third letter
  • 10-13 letters: fourth letter
  • 14+ letters: ~30% of word length

Development

# Install dependencies
npm install

# Start dev server
npm run dev

# Build for production
npm run build

Tips for Speed Reading

• Start at a comfortable speed (250-300 WPM)
• Gradually increase as you get comfortable
• Relax your eyes and let the words flow
• Don't subvocalize (say words in your head)
• Focus on the red letter - it stays in the same place
