JS Finger Tap Test

A browser-based finger tapping test built with JavaScript and MediaPipe. This tool measures tap frequency, inter-tap interval (ITI), and variability between taps, providing quantitative metrics that can be useful for motor and cognitive research.

Features

• Real-time tracking of index finger and thumb taps using a webcam.
• Calculates tap count, mean inter-tap interval, and variability.
• Fully browser-based, no installation required.
• Lightweight and easy to integrate into studies or experiments.

Usage

1. Open `index.html` in a modern web browser with camera access.
2. Allow webcam access when prompted.
3. Tap your index finger and thumb together in front of the camera.
4. Real-time metrics will be displayed on the screen.

• `index.html` — Main HTML file.
• `style.css` — Styling for the interface.
