Abstract

Disclosed is a character inputting method, device and an intelligent terminal, the method including: when a virtual key in a virtual on-screen keyboard layout is selected, invoking a first probability statistical table matching at least one character having been displayed by at least one virtual key having been selected; displaying a part of the candidate characters with the highest combination probabilities or all of the candidate characters in the invoked first probability statistical table respectively on virtual keys in the virtual on-screen keyboard layout, and resetting focus on a preset virtual key, wherein any candidate character displayed on a virtual key configured with higher level has higher combination probability; and performing operations above periodically until an ideogram or a character sequence to be input is selected, and inputting the selected ideogram or the character sequence selected in an input area.

First claim

What is claimed is:

1. An apparatus for presenting a virtual on-screen keyboard layout, the apparatus comprising:
a display panel configured to display the virtual on-screen keyboard layout, the virtual on-screen keyboard layout including a plurality of keys each representing a corresponding character;
a receiver interface configured to receive a first control input from a remote control device, the first control input including a selection of a first selected key from the virtual on-screen keyboard layout;
a memory configured to store a plurality of probability statistical tables each including reference characters and matching combination probabilities for a respective combination character; and
a processor configured to:
select a first probability statistical table from the plurality of probability statistical tables having the respective combination character matching the corresponding character of the first selected key; and
rearrange the virtual on-screen keyboard layout displayed on the display panel according to the combination probabilities included in the first probability statistical table.

2. The apparatus of claim 1 , wherein:
the receiver interface is further configured to receive a second control input from the remote control device, the second control input including a selection of a second selected key from the virtual on-screen keyboard layout; and
the processor is further configured to:
select a second probability statistical table from the plurality of probability statistical tables having the respective combination character corresponding to the first selected key and the second selected key; and
rearrange the virtual on-screen keyboard layout displayed on the display panel according to the combination probabilities included in the second probability statistical table.

3. The apparatus of claim 1 , wherein the first probability statistical table includes probabilities of candidate ideograms or candidate character sequences associated with the corresponding character of the first selected key.

4. The apparatus of claim 3 , wherein the processor is further configured to:
control the display panel to display the candidate ideograms or candidate character sequences in a display area separately from the virtual on-screen keyboard layout.

5. The apparatus of claim 1 , wherein the first probability statistical table includes probabilities of candidate ideograms or candidate character sequences associated with the corresponding character of the first selected key; and
wherein the processor is further configured to:
control the display panel to display the candidate ideograms or candidate character sequences in a display area separately from the virtual on-screen keyboard layout, wherein the candidate ideograms and candidate character sequences are in a language different from a language of the corresponding character of the first selected key.

6. The apparatus of claim 1 , wherein:
the receiver interface is further configured to receive a switch control input from the remote control device; and
the processor is further configured to:
select a second probability statistical table from the plurality of probability statistical tables having the respective combination character corresponding to at least the first selected key, wherein the second probability statistical table includes probabilities of candidate ideograms or candidate character sequences associated with the corresponding character of at least the first selected key; and
change the virtual on-screen keyboard layout displayed on the display panel to replace existing keys of the virtual on-screen keyboard layout with the candidate ideograms or candidate character sequences included in the second probability statistical table.

7. The apparatus of claim 6 , wherein the candidate ideograms and candidate character sequences are in a language different from a language of the corresponding character of the first selected key.

8. A method for presenting a virtual on-screen keyboard layout, the method comprising:
displaying, on a display panel, the virtual on-screen keyboard layout, the virtual on-screen keyboard layout including a plurality of keys each representing a corresponding character;
receiving, through a receiver interface, a first control input from a remote control device, the first control input including a selection of a first selected key from the virtual on-screen keyboard layout;
storing, in a memory, a plurality of probability statistical tables each including reference characters and matching combination probabilities for a respective combination character; and
selecting, by a processor, a first probability statistical table from the plurality of probability statistical tables having the respective combination character matching the corresponding character of the first selected key; and
rearranging, by the processor, the virtual on-screen keyboard layout displayed on the display panel according to the combination probabilities included in the first probability statistical table.

9. The method of claim 8 , further comprising:
receiving, through the receiver interface, a second control input from the remote control device, the second control input including a selection of a second selected key from the virtual on-screen keyboard layout;
selecting, by the processor, a second probability statistical table from the plurality of probability statistical tables having the respective combination character corresponding to the first selected key and the second selected key; and
rearranging, by the processor, the virtual on-screen keyboard layout displayed on the display panel according to the combination probabilities included in the second probability statistical table.

10. The method of claim 8 , wherein the first probability statistical table includes probabilities of candidate ideograms or candidate character sequences associated with the corresponding character of the first selected key.

11. The method of claim 10 , further comprising:
controlling, by the processor, the display panel to display the candidate ideograms or candidate character sequences in a display area separately from the virtual on-screen keyboard layout.

12. The method of claim 8 , wherein the first probability statistical table includes probabilities of candidate ideograms or candidate character sequences associated with the corresponding character of the first selected key; and
further comprising:
controlling, by the processor, the display panel to display the candidate ideograms or candidate character sequences in a display area separately from the virtual on-screen keyboard layout, wherein the candidate ideograms and candidate character sequences are in a language different from a language of the corresponding character of the first selected key.

13. The method of claim 8 , further comprising:
receiving, through the receiver interface, a switch control input from the remote control device;
selecting, by the processor, a second probability statistical table from the plurality of probability statistical tables having the respective combination character corresponding to at least the first selected key, wherein the second probability statistical table includes probabilities of candidate ideograms or candidate character sequences associated with the corresponding character of at least the first selected key; and
changing, by the processor, the virtual on-screen keyboard layout displayed on the display panel to replace existing keys of the virtual on-screen keyboard layout with the candidate ideograms or candidate character sequences included in the second probability stat
