Abstract

A method and an apparatus input test in a touch screen terminal. The method comprises designating a certain region on a keyboard interface picture, not permitting text input through a keyboard when touch drag started from the designated region is sensed and acquiring a path of the touch drag, acquiring a path of following touch drag when at least the one or more following touch drag are sensed, and reading out at least the acquired one or more paths by cursive character recognition, deducing a character, determining the deduced character as an input target, and permitting the text input through the keyboard.

Claims

1. A portable communication device comprising:

a touchscreen display; and

a processor configured to;

display a text input area in a first area and a virtual keyboard including a plurality of keys in a second area below the first area by using the touchscreen display;

while displaying the text input area and the virtual keyboard, receive a drag input moving from an area that is outside of the second area toward the second area;

while a contact of the drag input is maintained on the touchscreen display, recognize a path of the drag input moving across over any one of the plurality of keys included in the virtual keyboard as a part of a handwriting character instead of a key input of the virtual keyboard, wherein the handwriting character is different from all of a plurality of characters that are supportable by the plurality of keys; and

display, in the text input area, the handwriting character obtained based at least in part on the path of the drag input.

2. The portable communication device of claim 1, wherein the handwriting character is a Chinese character.

3. The portable communication device of claim 2, wherein the processor is further configured to:

display an image of the path of the drag input over the displayed virtual keyboard before displaying the handwriting character in the text input area.

4. The portable communication device of claim 3, wherein the processor is configured to:

based on displaying the handwriting character in the text input area, terminate to display the image of the path of the drag input over the displayed virtual keyboard.

5. The portable communication device of claim 1, wherein the processor is further configured to:

receive at least one drag input subsequent to the drag input while a handwriting character recognition mode is enabled, wherein the handwriting character recognition mode is enabled in response to an initiation of the drag input;

while the handwriting character recognition mode is enabled and a contact of the at least one drag input is maintained on the touchscreen display, recognize a path of the at least one drag input moving across over any one of the plurality of keys as another part of the handwriting character instead of a key input of the virtual keyboard;

display an image of at least portion of the path of the drag input and the path of the at least one drag input; and

display, in the text input area, the handwriting character obtained based at least in part on the path of the drag input and the path of the at least one drag input.

6. The portable communication device of claim 5, wherein the at least one drag input is received within a designated time from a timing at which the drag input is released.

7. The portable communication device of claim 1, wherein the processor is further configured to:

while displaying the text input area and the virtual keyboard, receive another drag input initiated from the second area;

in response to the reception of the other drag input initiated from the second area, recognize a path of the drag input initiated from the second area as an input on at least one key among the plurality of keys; and

display at least one character indicated by the at least one key in the text input area.

8. The portable communication device of claim 7, wherein the processor is further configured to:

based on the reception of the other drag input initiated from the second area, defer enabling a handwriting character recognition mode.

9. The portable communication device of claim 8, wherein the at least one character is displayed beside the handwriting character, if the other drag input initiated from the second area is received after a release of the drag input moving from the area that is outside of the second area toward the second area.

10. The portable communication device of claim 9, wherein all of the plurality of keys are disabled for recognizing the path of the drag input moving across over any one of the plurality of keys as the part of the handwriting character instead of a key input of the virtual keyboard, while the handwriting character recognition mode is enabled.

11. A method executed in a portable communication device with a touchscreen display, the method comprising:

displaying a text input area in a first area and a virtual keyboard including a plurality of keys in a second area below the first area by using the touchscreen display;

while displaying the text input area and the virtual keyboard, receiving a drag input moving from an area that is outside of the second area toward the second area;

while a contact of the drag input is maintained on the touchscreen display, recognizing a path of the drag input moving across over any one of the plurality of keys included in the virtual keyboard as a part of a handwriting character instead of a key input of the virtual keyboard, wherein the handwriting character is different from all of a plurality of characters that are supportable by the plurality of keys; and

displaying, in the text input area, the handwriting character obtained based at least in part on the path of the drag input.

12. The method of claim 11, wherein the handwriting character is a Chinese character.

13. The method of claim 12, further comprising:

displaying an image of the path of the drag input over the displayed virtual keyboard before displaying the handwriting character in the text input area.

14. The method of claim 13, further comprising:

based on displaying the handwriting character in the text input area, terminating to display the image of the path of the drag input over the displayed virtual keyboard.

15. The method of claim 11, further comprising:

receiving at least one drag input subsequent to the drag input while a handwriting character recognition mode is enabled, wherein the handwriting character recognition mode is enabled in response to an initiation of the drag input;

while the handwriting character recognition mode is enabled and a contact of the at least one drag input is maintained on the touchscreen display, recognizing a path of the at least one drag input moving across over any one of the plurality of keys as another part of the handwriting character instead of a key input of the virtual keyboard;

displaying an image of at least portion of the path of the drag input and the path of the at least one drag input; and

displaying, in the text input area, the handwriting character obtained based at least in part on the path of the drag input and the path of the at least one drag input.

16. The portable communication device of claim 15, wherein the at least one drag input is received within a designated time from a timing at which the drag input is released.

17. A non-transitory computer readable storage medium storing one or more programs, the one or more programs comprising instructions which, when executed by an electronic device with a touchscreen display, cause the electronic device to:

display a text input area in a first area and a virtual keyboard including a plurality of keys in a second area below the first area by using the touchscreen display;

while displaying the text input area and the virtual keyboard, receive a drag input moving from an area that is outside of the second area toward the second area;

while a contact of the drag input is maintained on the touchscreen display, recognize a path of the drag input moving across over any one of the plurality of keys included in the virtual keyboard as a part of a handwriting character instead of a key input of the virtual keyboard, wherein the handwriting character is different from all of a plurality of characters that are supportable by the plurality of keys; and

display, in the text input area, the handwriting character obtained based at least in part on the path of the drag input.
