⚡ Quick Start

Install and launch Volatouch in seconds from your command line:

# 1. Install via pip (ultra-lightweight package, <100 KB)
pip install volatouch

# 2. Start the air control server
volatouch

Once running, open the URL displayed in the terminal (e.g. http://192.168.1.5:8000) in Safari or Chrome on any phone connected to the same Wi-Fi.
No mobile app installation, no registration, no configuration required!

🌟 Why Volatouch?

• 🪶 100% Standalone & Zero-Bloat:

  • No 100 MB OpenCV Dependency: Uses a lightweight PIL engine by default (~3 MB) with optional automatic OpenCV acceleration if available.
  • Self-Contained Web Client: The complete, modern React + Tailwind touch interface is pre-bundled directly within the package (~220 KB). You don't need Node.js, npm, or any frontend build step at runtime.
  • Total package wheel size is under 100 KB!

• ⚡ Hardware-Level 60 FPS & Near-Zero Latency:

  • Screen frames captured at the hardware display level via mss.
  • Transmitted over WebSockets as raw Binary ArrayBuffers (no Base64 overhead).
  • Single-slot atomic queues (asyncio.Queue(maxsize=1)) prevent buffer bloat and frame queuing.
  • Rendered client-side on an HTML5 <canvas> using createImageBitmap and requestAnimationFrame.

• 🎯 Dual Navigation Modes:

  • Direct Target Mode: Tap anywhere on your phone to instantly teleport the cursor to that point on your PC display.
  • Relative Trackpad Mode: Smooth trackpad navigation with acceleration and configurable sensitivity.

✨ Features

• 🏝️ Draggable Floating Action Island:

  • Dedicated L-Click and R-Click buttons.
  • HOLD / LOCKED Button: One-touch left-click lock with tactile vibration feedback for moving windows and drag-and-drop.
  • UP & DOWN Scroll Buttons: Dedicated micro-step mouse wheel scrollers.
  • Collapsible Mini-Pill: Minimize the controls into a small floating dot to maximize visible screen real estate.
  • Boundary Clamping: Widgets automatically re-align to stay safely within the viewport on orientation change or fullscreen.

• ⌨️ Comprehensive Built-In Virtual Keyboard:

  • Full QWERTY layout with dynamic Caps / Shift character switching.
  • Sticky Modifier Keys: Ctrl, Shift, Alt, and Win (Super) lock on tap (highlighted in indigo) for desktop shortcuts (e.g., Ctrl + C).
  • Function keys (F1–F12), navigation keys (Esc, Tab, Home, End), and a Voice / Text drawer.

• 📱 Landscape Edge-to-Edge Fill:

  • Toggle between Fit (aspect ratio preservation) and Fill (edge-to-edge stretch) to eliminate black side bars on widescreen mobile devices.

• 🌐 English & Turkish Language Support:

  • Default English interface with an instant Turkish language switcher saved in localStorage.

Volatouch: Ultra-Low Latency Mobile Air Control & Wireless Trackpad for PC over Wi-Fi.

options:
  -h, --help            Show this help message and exit
  --host HOST           Host network interface to bind (default: 0.0.0.0)
  -p PORT, --port PORT  Port to listen on (default: 8000)
  -q QUALITY, --quality QUALITY
                        Initial JPEG stream quality (10-100, default: 55)
  -s SCALE, --scale SCALE
                        Initial resolution scale (0.2-1.0, default: 0.70)
  -v, --version         Show program's version number and exit

Examples:

# Run on custom port
volatouch -p 8080

# Run with higher image quality
volatouch -q 75 -s 0.85

🛡️ Security & Sandbox

1. Subnet Verification (RFC-1918): Only devices within the same /24 private local Wi-Fi subnet can access endpoints or establish WebSocket handshakes. External requests receive an immediate 403 Forbidden.
2. Strict Origin & CSP Protection: Enforces modern Content-Security-Policy, X-Frame-Options: DENY, and strict frame-ancestors restrictions.
3. Whitelisted Hardware Commands: Only explicit, sanitized commands (mouse_move, mouse_click, key_tap, etc.) are processed. Arbitrary command execution is impossible.
4. Failsafe Key Release: When a WebSocket connection drops, all pressed keys and mouse buttons are instantly released via input_ctrl.release_all() to prevent stuck keys.
