OpenTabletDriver
OpenTabletDriver is a user-mode graphics tablet driver and USB HID input manager that translates raw USB input from digitizer hardware into system cursor and pen events. It serves as a hardware abstraction layer that normalizes input from various tablet brands into a consistent API, providing a cross-platform pen interface with pressure and tilt sensitivity.
The project distinguishes itself through a plugin-based architecture and a profile-based configuration system, allowing for custom filters, interpolators, and persistent hardware setups. It includes specialized tools for hardware driver development, such as raw USB packet analysis, hardware packet inspection, and a debugger for input value validation.
The software covers broad capability areas including input mapping for defining active surface areas and binding express keys to keyboard or mouse actions. It handles pen pressure processing and system ink integration, utilizing kernel-level input injection to ensure compatibility with software that blocks standard user-mode APIs.
Management and diagnostics are supported through a command-line interface for driver control and real-time log monitoring.
