GCMD — The Future of Human-Computer Interaction

Control your computer with gestures. No keyboard. No mouse. Just motion.

---

What Is GCMD?

GCMD is a gesture-based UI navigation system that turns your webcam into a powerful spatial interface.
Think Raycast, but for your hands.

Navigate, control, and command your desktop environment using nothing but natural hand movements — in the air, in real-time, with depth-aware precision.

🎯 NEW: Enhanced 3D Hand Tracking System

Our latest release introduces revolutionary hand tracking capabilities:

• 🎮 3D Laser Pointer System: Infinite laser beam that extends from your hand to a distant wall
• 🎯 Aim & Background Control: Precise cursor control with magnetic snapping to center
• 🔫 Point & Shoot Gaming: Gun mechanics with realistic aiming and shooting
• 🚗 Car Driving Simulation: Vehicle control using hand gestures
• ⚙️ Calibration System: Adjustable sensitivity and hand range for perfect control
• 🖱️ Real Mouse Control: Actual mouse events sent to browser for game integration
• ✨ Zero Jitter Movement: Ultra-smooth cursor with 0.99 smoothing factor

🎮 Interactive Modes

1. 🎯 Aim & Background:

   • Hand stays centered horizontally
   • Vertical movement controls aiming
   • Calibrated Y-axis sensitivity
   • Strong magnetic snapping to center
   • Infinite yellow laser pointer

2. 🔫 Point & Shoot:

   • Gun barrel from wrist to knuckle
   • Laser follows actual pointing direction
   • Full fist = Shoot
   • Realistic 3D physics simulation
   • Target hit detection and explosions

3. 🚗 Car Driving:

   • Hand gestures control vehicle
   • Steering, acceleration, braking
   • Real-time physics simulation
   • Immersive driving experience

4. 🖱️ Mouse Test:

   • Real mouse cursor control
   • Works with any web app/game
   • Browser integration ready

Why GCMD?

We built GCMD to challenge the status quo of human-computer interaction.

While most systems today rely on clicks, taps, or voice — GCMD introduces a new layer: spatial interaction.

This isn’t just a tool for accessibility.
This is a productivity upgrade — for creators, developers, artists, power users, and visionaries who want to:

• Navigate faster
• Trigger commands with gestures
• Move objects across 3D space
• Control apps, windows, media, and more — with air-touch

How It Works

• Uses your built-in camera (e.g., MacBook's FaceTime)
• Tracks hand gestures using MediaPipe + Tensorflow.js
• Projects your hand into a 3D interactive field on your screen
• Interprets gestures as UI commands: scroll, click, swipe, zoom, etc.
• Includes a depth-based z-axis using motion parallax for realistic 3D control
• NEW: 3D laser pointer system with infinite beam projection
• NEW: Calibrated aiming with magnetic snapping and zero jitter
• NEW: Real mouse event simulation for browser game integration

🎯 Advanced Hand Tracking Features

• Infinite Laser Pointer: 10-meter laser beam from hand to distant wall
• Precise Aiming: Calibrated Y-axis sensitivity with adjustable hand range
• Magnetic Snapping: Automatic center attraction with smooth return
• Zero Jitter: Ultra-smooth cursor movement with 0.99 smoothing factor
• Real Mouse Control: Actual mousemove, mousedown, mouseup events
• 3D Physics: Realistic intersection calculations and depth perception
• Gesture Recognition: Pointing, shooting, dragging, and driving gestures

The closer you move your hand to the camera, the deeper you reach into your screen.
NEW: Point your hand to aim, make a fist to shoot, extend fingers to drag.

The Vision

GCMD is more than a tool — it’s a new standard.

We are building toward a future where:

• Your hands appear inside your screen with spatial awareness
• You can pinch windows to close, swipe to switch apps, and grab 3D objects
• You interact with your computer like it's an extension of your body
• Every movement, from the twitch of a finger to a sweeping gesture, is fluid, intuitive, and productive

We're leveraging the best of 3D web tech (Three.js) and gesture AI (MediaPipe, TensorFlow.js) to craft a natural, immersive interface.
