Prototype Controller Input Event Routing for GUI Testing

The patent introduces a prototype controller as an intermediary component that manages input event routing between the prototype layer and the underlying application. The controller receives input events, determines whether they are intended for the prototype or the application, and routes them accordingly. This mediator approach enables the prototype to be tested with full input event access while preventing unwanted interception, as the controller intelligently directs events to the appropriate target based on the current interaction state.

The patent implements dynamic input event routing where the prototype controller adjusts its priority level and event reception behavior based on the current operational state. When the prototype is active and needs testing, the controller receives input events with top priority. When the prototype is inactive or when certain conditions are met, the controller allows events to pass through to the underlying application. This dynamic adjustment ensures both high prototype testing efficiency and reliable application input reception as needed.

The patent segments the user interface into distinct functional layers: the application layer and the prototype layer, with the prototype controller managing the prototype layer. This segmentation allows the prototype to be stacked as a separate layer higher than the application, enabling transparent stacking and seamless integration. The prototype controller handles the complexity of layered structure management, while the application maintains its original structure, thus achieving adaptability without permanently increasing application complexity.
