Abstract

Text is entered into an electronic communications device by means of a keypad having a number of keys, each key representing a plurality of letters and/or character sequences, entered text is displayed on a display on the device. Possible character sequences corresponding to an activated key sequence are generated. These are compared with a stored vocabulary comprising character sequences representing words as well as word stems occurring in a given language. Those stored character sequences that match the possible character sequences are pre-selected and a number of these are presented in a separate graphical object arranged predominantly on the display.

Claims

1. A method of entering text into an electronic communications device by means of a keypad having a number of keys, each key representing a plurality of characters, and wherein entered text is displayed on a display arranged on the electronic communications device, the method comprising:

activating a sequence of keys;

generating possible character sequences corresponding to said activated key sequence;

comparing said possible syllables with a vocabulary stored in a memory, said vocabulary comprising character sequences representing words occurring in a given language;

pre-selecting those of said possible character sequences that match character sequences stored in said vocabulary; and

presenting a number of the pre-selected character sequences on said display in a separate graphical object, wherein the separate graphical object is arranged predominantly on the display so that it covers at least a part of the existing display.

2. A method according to claim 1, further comprising:

indicating distinctly one of the character sequences presented in said separate graphical object.

3. A method according to claim 2, further comprising:

rank ordering the pre-selected character sequences according to their frequency of use in said language; and

indicating distinctly as default the most commonly used character sequence in said separate graphical object.

4. A method according to claim 2, further comprising:

allowing a user to indicate distinctly a different one of said pre-selected character sequences.

5. A method according to claim 2, further comprising:

allowing a user to select the indicated character sequence; and

adding the selected character sequence to the text displayed on the display.

6. A method according to claim 5, further comprising:

removing said separate graphical object from the display when a character sequence has been selected.

7. A method according to claim 1, further comprising:

removing said separate graphical object from the display when a predefined period of time has elapsed since the last activation of a key.

8. A method according to claim 4, further comprising:

arranging said number of pre-selected character sequences vertically in said separate graphical object.

9. A method according to claim 8, wherein allowing a user to indicate distinctly a different one of said pre-selected character sequences is performed by allowing the user to navigate between individual pre-selected character sequences by activating an upwards-key for indicating a character sequence presented just above the character sequence presently indicated, and by activating a downwards-key for indicating a character sequence presented just below the character sequence presently indicated.

10. A method according to claim 9, further comprising:

allowing the user, in the case where not all pre-selected character sequences are presented in said separate graphical object, to exclude one of the presently presented character sequences and instead present a character sequence not presently presented by activation of one of the upwards- and downwards-keys.

12. A method according to claim 1, further comprising:

adjusting the width of said separate graphical object according to the length of the character sequence being presented.

13. A method according to claim 1, further comprising:

presenting the character sequences in said separate graphical object with a font size which is adjusted according to the length of the character sequence being presented.

14. A method according to claim 1, further comprising:

comparing said possible character sequences with a vocabulary comprising character sequences representing words as well as word stems occurring in said given language.

15. A method according to claim 2, further comprising:

showing a cursor in combination with the distinctly indicated character sequence.

16. A method according to claim 1, further comprising:

keeping text that is displayed outside said separate graphical object unchanged as long as said separate graphical object is shown on the display.

17. A method according to claim 1, further comprising:

updating text that is displayed outside said separate graphical object at a low rate compared to the key activation rate as long as said separate graphical object is shown on the display.

19. An electronic communications device according to claim 17, wherein said presenting means is further configured to indicate distinctly one of the character sequences presented in said separate graphical object.

20. An electronic communications device according to claim 19, wherein the device is further configured to rank order the pre-selected character sequences according to their frequency of use in said language, and indicate distinctly as default the most commonly used character sequence in said separate graphical object.

21. An electronic communications device according to claim 19 wherein the device is further configured to allow a user to indicate distinctly a different one of said pre-selected character sequences.

22. An electronic communications device according to claim 19, wherein the device is further configured to allow a user to select the indicated character sequence, and add the selected character sequence to the text displayed on the display.

23. An electronic communications device according to claim 22, wherein the device is further configured to remove said separate graphical object from the display when a character sequence has been selected.

25. An electronic communications device according to claim 21, wherein the device is further configured to present said number of pre-selected character sequences vertically in said separate graphical object.

26. An electronic communications device according to claim 25, wherein the device is further configured to allow a user to indicate distinctly a different one of said pre-selected character sequences by allowing the user to navigate between individual pre-selected character sequences by activating an upwards-key for indicating a character sequence presented just above the character sequence presently indicated, and by activating a downwards-key for indicating a character sequence presented just below the character sequence presently indicated.

27. An electronic communications device according to claim 26, wherein the device is further configured to allow the user, in the case where not all pre-selected character sequences are presented in said separate graphical object, to exclude one of the presently presented character sequences and instead present a character sequence not presently presented by activation of one of the upwards- and downwards-keys.

32. An electronic communications device according to claim 19, wherein the device is further configured to show a cursor in combination with the distinctly indicated character sequence.
