Abstract: This application provides a method and apparatus for processing an interaction event. The method may be performed by a unified interaction framework. Behavior identification of the interaction event is performed by the unified interaction framework, and a widget may directly execute the interaction behavior identified by the unified interaction framework. The widget does not need to adapt to an interactive device. When a software system needs to adapt to a newly added interactive device, a developer can perform adaptation development on the unified interaction framework once to adapt the newly added interactive device for a plurality of widgets.
