  • Methods and Devices for Presenting a Keyboard Having Separate Alphabetic and Special Character Sections on a User Interface
    Publication number: 20240302956
    Abstract: An electronic device includes a user interface configured to display content and receive user input. One or more processors operable with the user interface cause the user interface to display a virtual keyboard that includes a first section having a first plurality of virtual keys corresponding to a plurality of alphabetic characters and a second section having a second plurality of virtual keys corresponding to a plurality of special characters. The first section and the second section are separated by a translatable slider. The translatable slider can be manipulated, manually or automatically, to increase the area occupied by the first section, thereby revealing more virtual keys corresponding to more alphabetic characters, or alternatively to increase the area occupied by the second section to reveal more virtual keys corresponding to more special characters.
