Stylus Movement Detection for Application Activation

The system pre-positions the application activation logic to trigger automatically when specific conditions are met (call mode detection + stylus movement detection), eliminating the need for users to navigate through menus during calls. The detection unit continuously monitors for these conditions, and when detected, the processing unit immediately activates the application, saving significant time.

The system performs self-service by automatically detecting the user's intent through stylus movement and autonomously activating the appropriate application without requiring manual menu navigation. The detection unit and processing unit work together to automatically initiate the application based on predefined conditions, making the system serve itself rather than requiring complex user interaction.

The detection unit serves multiple functions: it detects both call mode activation and stylus movement, and can trigger different applications based on the detected conditions. The processing unit also handles multiple tasks including mode switching, application activation, and coordinate detection. This multi-functionality reduces the need for separate dedicated components for each function.

The patent combines the detection unit and processing unit into an integrated system that handles both call mode detection and stylus movement detection through unified logic. The processing unit merges multiple detection functions and application activation logic into a single control mechanism, reducing overall system complexity while maintaining high productivity.
