Abstract

Swipe-stroke input and continuous handwriting are provided. A stroke sequence or a portion of a stroke sequence of a Chinese character may be input via selecting one or more stroke buttons via a swipe gesture. Candidate characters may be determined and provided when an indication is received that a stroke sequence input has ended. A candidate may be selected, or a next stroke sequence may be input. As additional input is received, phrase candidates may be predicted and dynamically provided. An end-of-input (EOI) panel may be provided, which when selected, provides an indication of an end of a current handwriting input and allowing a next handwriting input to be entered. By providing a selectable functionality to indicate an end of a current handwriting input, a continuous and more efficient handwriting experience is provided. Past handwriting input may be stored and accessed, allowing a user to edit the past handwriting input.

Claims

1. A method for providing swipe-stroke input of Chinese text, the method comprising:

receiving a stroke sequence input via receiving an indication of a selection of one or more stroke buttons;

determining one or more character candidates according to the received stroke sequence input;

determining if an indication of a selection of a character candidate is received;

when an indication of a selection of a character candidate is received, displaying the selected character candidate; and

when an indication of a selection of a character candidate is not received, receiving a next stroke sequence input and determining one or more candidate phrases according to the received stroke sequence inputs.

2. The method of claim 1, wherein receiving a stroke sequence input comprises receiving a complete or a portion of a character stroke sequence.

3. The method of claim 1, further comprising displaying a plurality of stroke buttons and wherein displaying a plurality of stroke buttons comprises displaying a plurality of stroke buttons on a touchscreen interface.

4. The method of claim 3, wherein receiving a stroke sequence input via receiving an indication of a selection of one or more stroke buttons comprises receiving an indication of a selection of one or more stroke buttons via a swipe-stroke gesture.

5. The method of claim 4, wherein prior to determining one or more character candidates according to the received stroke sequence input, receiving an indication of an end of a stroke sequence input.

6. The method of claim 5, wherein receiving an indication of an end of a stroke sequence input comprises determining when a user'"'"'s finger is lifted from the touchscreen interface.

7. The method of claim 1, wherein the plurality of stroke buttons comprise a horizontal stroke button, a vertical stroke button, a downwards right-to-left stroke button, a dot or downwards left-to-right stroke button, and an all-other stroke button.

8. The method of claim 1, wherein after determining one or more candidate phrases according to the received stroke sequence inputs:

displaying the one or more candidate phrases;

receiving a selection of a candidate phrase; and

displaying the selected candidate phrase.

9. A method for providing continuous handwriting of Chinese text, the method comprising:

receiving a first handwriting input;

recognizing the first handwriting input as a first character;

receiving an indication of a selection of an end-of-input panel indicating an end of handwriting input for the first character;

receiving a second handwriting input; and

determining and displaying one or more word predictions according to received handwriting inputs.

10. The method of claim 9, further comprising providing a recognized character panel and displaying a recognized character in the recognized character panel.

11. The method of claim 10, further comprising receiving a selection of the recognized character and allowing editing of the handwriting input associated with the recognized character.

12. The method of claim 9, wherein receiving a first handwriting input comprises receiving a first handwriting input via a touchscreen interface.

13. The method of claim 12, wherein receiving an indication of a selection of an end of input panel comprises receiving an indication of a touch within the end-of-input panel.

14. The method of claim 12, wherein receiving an indication of a selection of an end-of-input panel comprises receiving an indication of a swipe gesture originating in the end of input panel.

15. The method of claim 9, further comprising prior to receiving a second handwriting input, determining and displaying one or more character candidates according to the first received handwriting input.

16. The method of claim 9, further comprising receiving a selection of a word prediction and displaying the selected word prediction.

17. A system for providing swipe-stroke input and continuous handwriting of Chinese text, the system comprising:

a memory storage; and

a processing unit coupled to the memory storage, wherein the processing unit is operable to;

display a plurality of stroke buttons;

receive a stroke sequence input via receiving an indication of a selection of one or more stroke buttons;

determine one or more character candidates according to the received stroke sequence input;

determine if an indication of a selection of a character candidate is received;

when an indication of a selection of a character candidate is received, display the selected character candidate;

when an indication of a selection of a character candidate is not received, receive a next stroke sequence input and determine one or more candidate phrases according to the received stroke sequence inputs;

receive a first handwriting input;

recognize the first handwriting input as a first character;

receive an indication of a selection of an end-of-input panel indicating an end of handwriting input for the first character;

receive a second handwriting input; and

determine and display one or more word predictions according to received handwriting inputs.

18. The system of claim 17, further comprising a touchscreen interface operable to receive input.

19. The system of claim 17, wherein the processor is further operable to:

provide a recognized character panel; and

displaying a recognized character in the recognized character panel.

20. The system of claim 19, wherein the processor is further operable to:

receive a selection of the recognized character; and

allow editing of the handwriting input associated with the recognized character.
