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.

Claims

1. A touch-typable device for accepting desired textual input from a user comprising:

a movable keymask comprising of a plurality of cells mapped with one or more keys of text input keypad of said touch-typable device, wherein each of said plurality of cells of said movable keymask superimposes over textual input choices enabling said user to select said desired textual input from said plurality of cells of said movable keymask using said text input keypad of said touch-typable device.

2. The touch-typable device as claimed in claim 1, wherein said movable keymask is positioned on display of said touch-typable device.

3. The touch-typable device as claimed in claim 1, wherein said textual input choices are chosen after every user input from a set of likely and valid input choices, wherein said likely and valid input choices are selected based on one or more of previous textual input sequence, phoneme and syllabary patterns, statistical correlation between said previous textual input sequence and set of textual input choices, dictionary lookups, and usage patterns of said user.

4. The touch-typable device as claimed in claim 3, wherein said user accesses a second set of said textual input choices on said movable keymask from said set of likely and valid input choices using said text input keypad of said touch-typable device in case said desired textual input is not present in said textual input choices.

5. The touch-typable device as claimed in claim 3, wherein said textual input choices chosen from said set of likely and valid input choices are superimposed on said movable keymask based on one or more of physical access of said user to said plurality of cells of said movable keymask, persistence of said textual input choice on said movable keymask, assignment of most likely textual input choices on previously accessed cell, layout of said textual input choices on said text input keypad of said touch-typable device, and nearness to last key used.

6. The touch-typable device as claimed in claim 1, wherein said movable keymask is superimposed over a character map comprising of said textual input choices, further wherein each of said plurality of cells of said movable keymask superimposes over a textual input choice of said character map.

7. The touch-typable device as claimed in claim 6, wherein said movable keymask is navigated over the said character map to access said textual input choices using said touch-typable device.

8. The touch-typable device as claimed in claim 1, wherein said movable keymask is adjacent to a character map comprising of said textual input choices, further wherein said textual input choices displayed in said movable keymask are dynamically changed based on said desired textual input selected and/or highlighted by said user in said character map.

9. The touch-typable device as claimed in claim 1, wherein said desired textual input is compressed based on statistical correlation between previously entered textual inputs.

10. The touch-typable device as claimed in claim 1, wherein said textual input choices support one or more languages and are positioned to enable language convertibility.

11. The touch-typable device as claimed in claim 1, wherein said textual input choices comprise of one or more of alphabets, words, multilingual character sets, symbols, mathematical symbols, formulas, and engineering codes.

12. The touch-typable device as claimed in claim 1, wherein said touch-typable device comprises of one or more of mobile phone, personal handyphone system (PHS), car phones, personal digital assistant, surface computer, pocket beepers, ATM'"'"'s, STB'"'"'s, touchscreen kiosks, gaming consoles, and remote controls for display devices such as televisions.

13. A method for accepting desired textual input from a user through a touch-typable device comprising:

generating a movable keymask comprising of a plurality of cells mapped with one or more keys of text input keypad of said touch-typable device,

superimposing said plurality of cells of said movable keymask over textual input choices; and

receiving said desired textual input from said plurality of cells of said movable keymask using said text input keypad of said touch-typable device.

14. The method of claim 13, wherein said movable key is configured to be partially or completely displayed on display of said touch-typable device.

15. The method of claim 13, further comprising allowing said user to select said desired textual input from a second set of textual input choices based on whether said desired textual input is present and displayed through said plurality of cells of said movable keymask, wherein if said desired textual input is not present and displayed through said plurality of cells of said movable keymask, said second set of textual input choices are displayed through said plurality of cells of said movable keymask using said touch-typable device.

16. The method of claim 13, wherein said textual input choices are dynamically chosen and displayed on said movable keymask after every user input from a set of likely and valid input choices, wherein said likely and valid input choices are selected based on one or more of previous textual input sequence, phoneme and syllabary patterns, statistical correlation between said previous textual input sequence and set of textual input choices, dictionary lookups, and usage patterns of said user.

17. The touch-typable device as claimed in claim 16, wherein said textual input choices chosen from said set of likely and valid input choices are superimposed on said movable keymask based on one or more of physical access of said user to said plurality of cells of said movable keymask, persistence of said textual input choice on said movable keymask, assignment of most likely textual input choices on previously accessed cell, layout of said textual input choices on said text input keypad of said touch-typable device, and nearness to last key used.

18. The method of claim 13, wherein said movable keymask can be scrolled to enable said user to access said textual input choices.
