User Interface Overloading: A Novel Approach for Handheld Device Text Input.

Text input with a PDA is not as easy as it should be, especially when compared to a desktop set up with a standard keyboard. The abundance of attempted solutions to the text input problem for mobile devices provides evidence of the difficulties, and suggests the need for more imaginative approaches. We propose a novel gesture driven layer interaction model using animated transparent overlays, which integrates agreeably with common windowing models. [ABSTRACT FROM AUTHOR]
