Desktop Assistant System Controls Module routes voice intents to hardware and OS APIs, enabling voice-driven management of volume, brightness, display lock, sleep, shutdown, and theme settings. The Intent Engine parses user commands and dispatches them to specialized control handlers—Volume Control, Brightness Control, Lock Screen, Sleep Mode, Shutdown, and Dark Mode Toggle—each bridging to native Windows APIs via PyWin32. This modular architecture decouples intent recognition from system-level operations, improving testability and extensibility. Fork this diagram on Diagrams.so to customize control handlers, add new intents, or adapt the Windows API layer for cross-platform support. The System State and Desktop Assistant UI components provide real-time feedback and status synchronization across the application.
