17 y/o developer. Building weird but useful tools. Hand Mouse — control your PC with just your hand.

Introduction

I’m 17 years old and built a small project to solve a simple problem: I wanted to control my computer without touching a mouse, even while lying in bed.

Hand Mouse

Hand Mouse is a webcam‑based mouse controller that lets you control your cursor using only your hand and a webcam—no extra hardware, no gloves, just your camera.

What you can do

• Move the mouse with your index finger
• Click by pinching your fingers
• Double‑click with a fist gesture

Why I built it

• Use my PC while lying down
• Avoid wrist strain
• Have a backup mouse when the real one broke

How it works

• Real‑time hand tracking
• Maps finger movement to screen space
• Smart smoothing to keep the cursor stable
• Click detection with freeze logic to avoid misclicks

I spent a lot of time tuning it to feel smooth, responsive, and not laggy.
