Biometric UI Flow for One-Hold Authentication and Function Selection

The patent merges the authentication input and function selection input into a single continuous input action. The biometric sensor receives a first input for authentication, and while this input is being held, a second input selects functions from displayed menus. This combining of sequential operations into one continuous gesture resolves the contradiction by eliminating the time loss and improving convenience while maintaining security through sequential processing of authentication followed by function selection.

The patent implements preliminary action by displaying function menus and icons during the authentication process itself, before authentication completes. This allows users to pre-select desired functions while the biometric verification is ongoing, so that immediately upon successful authentication, the selected function executes automatically. This preliminary selection action reduces the total time required and improves operational convenience.

The patent segments the function selection interface into hierarchical categories (menus and icons) that are displayed in an organized manner during authentication. Different functions are grouped and presented systematically, allowing users to navigate through segmented options rather than facing a complex undifferentiated list. This segmentation maintains versatility while reducing perceived complexity through structured presentation.

The patent adds a temporal dimension to the user interface by displaying function menus and icons dynamically during the authentication process. Instead of presenting all functions simultaneously in a complex static list, the system activates function selection in the time window during biometric verification, organizing options across multiple dimensions (menus for categories, icons for specific functions) to manage complexity while maintaining versatility.
