Abstract: Described systems and mechanisms relate to techniques for improving usability, speed, and accuracy of text input to touch-typable devices. A touch-typable device can include a movable keymask comprising of a plurality of cells mapped with one or more keys of text input keypad of the touch-typable device, wherein each of the plurality of cells of the movable keymask superimposes over textual input choices enabling the user to select the desired textual input from the plurality of cells of the movable keymask using the text input keypad of the touch-typable device. The textual input choices can be chosen after every user input from a set of likely input choices, wherein the likely input choices can be selected based on previous textual input sequence, phoneme and syllabary patterns, statistical correlation between the previous textual input sequence and set of textual input choices, dictionary lookups, and usage patterns of said user.
