dedHD – Cognitive Fatigue-Aware Interface Adapter

A Chrome extension that gently helps users regain focus by detecting ADHD behavioral patterns like rapid scrolling, jittery mouse movement, fast typing, and more.

Instead of blocking or restricting, dedHD provides subtle interventions like breathing exercises, UI adjustments, and reminders.

✨ Features

Behavior Detection

• Rapid mouse movement (restlessness)
• Fast scrolling / doomscrolling
• High typing speed (mental rush)
• Rage clicking (repeated clicks in same area)
• Idle → sudden activity spikes
• YouTube Shorts detection

---

🎯 Smart Interventions

• 🧘 Breathing assistant (calming overlay)
• 🔍 Focus mode (larger text, centered layout)
• 🌙 Calm mode (reduced visual intensity)
• 💬 Gentle popups (non-intrusive reminders)
• 📵 YouTube Shorts interruption (pause + prompt)

---

🧩 How It Works

The extension tracks short-term behavioral signals (last few seconds) and maps them to possible attention states.

Example:

• Fast typing → cognitive overload → breathing exercise
• Rage clicking → frustration → calming intervention
• Doomscrolling → passive consumption → blur + prompt

---

⚙️ Tech Stack

• JavaScript (Vanilla)
• Chrome Extensions API (Manifest v3)
• DOM event listeners (mousemove, scroll, keydown, click)

---

⚠️ Note

This extension does not diagnose ADHD.

It detects behavioral patterns that may correlate with distraction or overload, and offers helpful interventions.
