OpenMouse — Wireless PC Remote Control

April 18, 2026

OpenMouse turns your Android phone into a fully-featured input device for your PC over your local WiFi network. No cables, no drivers — install the Windows executable, launch the app, and you get a trackpad, keyboard and media controller in your pocket.

Built because, sometimes, your mouse dies mid-presentation.

• Wide touch zone for cursor movement
• Tap = left click
• Double tap = double click
• Long press = right click
• Dedicated side scroll bar + two-finger scroll

• Real-time key capture
• Text field to send whole phrases
• Uses Android's native keyboard

• Play / pause
• Next / previous
• Volume up / down / mute
• Large, easy-to-hit buttons

• Finds your PC automatically on the LAN (mDNS)
• Manual IP fallback
• Auto-reconnect on signal loss

• Run the .exe and you're done — self-installs and auto-starts
• System tray icon shows IP and status
• Auto-start on Windows boot
• Uninstall from the tray menu

A lightweight binary protocol optimized for low latency:

| Channel | Port | Use | Latency | |---|---|---|---| | UDP | 19780 | Mouse movement, scroll | ~1-5ms | | TCP | 19781 | Keyboard, clicks, multimedia | Reliable |

Mouse packets are sent 60-100 times per second at only 5 bytes each, producing a fluid, near-instant experience.

• PC Server: Python 3.11+ with asyncio (UDP + TCP listeners), pynput (input simulation), pystray (tray icon), zeroconf (mDNS), PyInstaller (packaging)
• Android App: Flutter with dart:io (UDP/TCP) and bonsoir (mDNS discovery)
• Platforms: Windows 10+, Linux, Android 5.0+
