Lisainput

Lisainput is a cross-platform input framework designed to unify user input from keyboards, pointers, touch, stylus, voice, and game controllers. It provides an abstract input event model and a set of adapters that allow applications to receive normalized events regardless of source device.

Its architecture centers on a lightweight core event bus, per-device drivers, platform shims, and language bindings for C++, JavaScript, Python, and other languages. Lisainput defines an event model with types such as KeyEvent, PointerEvent, GestureEvent, TextInputEvent, VoiceInputEvent, and DeviceEvent. An optional normalization layer handles time stamps, coordinate spaces, scaling, and multi-device coordination so applications can treat input uniformly.

The framework includes an extensible plugin system, support for accessibility features (screen reader compatibility, high-contrast rendering, and magnification), and input shaping capabilities (dead zones, sensitivity curves, and hysteresis) to improve precision and comfort. It also provides mechanisms for input routing decisions based on context, which helps manage inputs from multiple sources in complex applications.

Lisainput is used by desktop and mobile applications and provides bindings for major platforms including Windows, macOS, Linux, iOS, Android, and web environments through compiled or interpreted bindings. It emphasizes interoperability with existing UI toolkits and input APIs while maintaining a cohesive API surface for developers.

Governance is open and collaborative, with community-driven development, permissive licensing, and documentation aimed at ensuring consistent behavior across platforms. See also: input method, event-driven programming, human-computer interaction, accessibility.
