CellWriter is a grid-entry natural handwriting input panel. As you write characters into the cells, your writing is instantly recognized at the character level. When you press 'Enter' on the panel, the input you entered is sent to the currently focused application as if typed on the keyboard. Writer-dependent, CellWriter learns your handwriting for reliable recognition. Correcting preprocessor algorithms account for digitizer noise, differing stroke order, direction, and number of strokes. Unicode support enables you to write in any language.

OneStroke is a gesture-based character input program. Because a tablet PC in tablet mode does not have a keyboard, a software replacement is necessary. OneStroke aims to be a more elegant replacement to the bulky on-screen keyboard. Single-stroke gestures drawn on the main window generate X11 keyboard events in the currently focused window as if typed on the keyboard. This program has been succeeded by CellWriter, please see http://risujin.org/cellwriter or http://freshmeat.net/projects/cellwriter for more information.
