Mouse Stabilizer

Windows application inspired by paint tool stroke stabilization features. Reduces visual noise from mouse tremors during presentations and tutorial video creation. Perfect for those who are particular about smooth cursor movement on screen.

Features

• Tabbed Settings UI: Right-click system tray > Settings... for configuration
• Paint-style Following: Cursor smoothly follows target position like drawing software
• Follow Strength: Configurable follow strength (0.05-1.0)
• Ease Types: Multiple easing curves (Linear, Ease In, Ease Out, Ease In-Out)
• Delay Start: Configurable delay start (0-500ms) before smoothing begins
• Dual Mode: Adaptive smoothing that responds to movement velocity
• Target Cursor Types: Circle or cross pointer shapes for visual feedback
• Target Size: Adjustable target pointer size
• Transparency: Configurable transparency levels
• OBS Hiding: Screen capture exclusion for streaming/recording
• Always Visible Target: Always visible mode or auto-hide based on distance
• Hotkey Toggle: Ctrl+Alt+S to instantly enable/disable
• System Tray Integration: Complete control through system tray interface

Quick Start

1. Run: mouse_stabilizer.exe
2. Configure: Right-click system tray > Settings...
3. Toggle: Press Ctrl+Alt+S or right-click tray icon

Settings

Access all settings through Right-click system tray > Settings...

Basic Tab

• Follow Strength: Controls smoothing intensity
• Ease Type: Smoothing curve selection
• Delay Start: Wait time before stabilization begins
• Dual Mode: Velocity-responsive smoothing

Visual Tab

• Target Cursor Type: Circle or cross shapes
• Size: Target pointer size adjustment
• Transparency: Alpha blending control
• Hide from OBS: Screen capture exclusion
• Always Visible: Visibility mode control

Debug Tab

• Advanced logging and diagnostic options

Technical Specifications

• Compatibility: Windows 10/11
• CPU Usage: < 1%
• Memory Usage: < 5MB
• Latency: < 8ms real-time processing

Troubleshooting

• Settings not saving: Ensure write permissions in application directory
• Target pointer not visible: Check transparency settings or always visible mode
• OBS capture exclusion not working: Try compatibility mode in Debug tab
• Stabilization feels delayed: Reduce delay start time or increase follow strength

Architecture

Modular architecture with separated UI and core functionality:

• Settings UI (settings_ui.c): Tabbed configuration interface
• Target Pointer (target_pointer.c): Cross/circle visual feedback with capture exclusion
• Stabilizer Core (smooth_engine.c): Real-time smoothing algorithms
• System Integration (tray_ui.c, hotkey.c): Windows system tray and hotkey handling
