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 method to input a text in an electronic device including a touch screen, the method comprising:

designating an input window, a keyboard, and a region on the touch screen;

detecting whether a touch input is started from the keyboard or the designated region, wherein the designated region is a region on the touch screen having an area that is less than a total area of the touch screen;

in response to detecting the touch input starting from the keyboard, detecting a key on the keyboard that corresponds to the detected touch input and identifying a first character that corresponds to the detected key;

in response to detecting the touch input starting from the designated region, disabling a text input mode through the keyboard to allow the touch input to extend into the keyboard, acquiring at least one or more paths of the detected touch input, and identifying a second character using character recognition based on the acquired one or more paths; and

inputting the first or second character in the input window.

2. The method of claim 1, further comprising displaying at least the one or more paths of the detected touch input.

3. The method of claim 2, further comprising removing a display of the at least one or more paths of the detected touch input after inputting the first or second character.

4. The method of claim 1, further comprising enabling the text input mode through the keyboard after inputting the second character that is identified using character recognition based on the acquired one or more paths.

5. The method of claim 1, wherein inputting the second character which is identified using character recognition based on the acquired one or more paths is performed in response to identifying that no touch input is sensed within a threshold time after a previous touch input is released.

6. The method of claim 1, further comprising resizing or repositioning the designated region in response to a request from a user input.

7. The method of claim 1, further comprising determining when the touch input is continued toward a new point on the touch screen that is out of the designated region from an original point of the designated region.

8. The method of claim 1, wherein the touch input is capable of being input via an entire region of the touch screen.

9. An electronic device comprising:

a touch screen; and

a controller configured to;

designate an input window, a keyboard, and a region on the touch screen,

detect whether a touch input is started from the keyboard or the designated region, wherein the designated region is a region on the touch screen having an area that is less than a total area of the touch screen,

in response to detecting the touch input starting from the keyboard, detect a key on the keyboard that corresponds to the detected touch input and identify a first character that corresponds to the detected key,

in response to detecting the touch input starting from the designated region, disable a text input mode through the keyboard to allow the touch input to extend into the keyboard, acquire at least one or more paths of the detected touch input, and identify a second character using character recognition based on the acquired one or more paths, and

input the first or second character in the input window.

10. The electronic device of claim 9, wherein the controller is configured to display the at least one or more paths of the detected touch input.

11. The electronic device of claim 10, wherein the controller is configured to remove a display of the one or more paths of the detected touch input after inputting the first or second character.

12. The electronic device of claim 9, wherein the controller is configured to enable the text input through the keyboard after inputting the second character which is identified using character recognition based on the acquired one or more paths.

13. The electronic device of claim 9, wherein the controller is configured to input the second character which is identified using character recognition based on the acquired one or more paths in response to identifying that no touch input is sensed within a threshold time after a previous touch input is released.

14. The electronic device of claim 9, wherein the controller is configured to resize or reposition the designated region in response to a request from a user input.

15. The electronic device of claim 9, wherein the controller is configured to determine when the touch input is continued toward a new point on the touch screen that is out of the designated region from an original point of the designated region.

16. The electronic device of claim 9, wherein the touch input is capable of being input via an entire region of the touch screen.

17. An electronic device, comprising:

a touch screen; and

a controller configured to;

designate an input window, a keyboard, and a region on the touch screen,

detect whether a touch input is started from the keyboard or the designated region, wherein the designated region is a region on the touch screen having an area that is less than a total area of the touch screen,

in response to detecting the touch input starting from the keyboard, detect a key on the keyboard that corresponds to the detected touch input and identify a first character that corresponds to the detected key,

in response to detecting the touch input starting from the designated region, disable a text input mode through the keyboard, acquire at least one or more paths of the detected touch input on the keyboard and the designated region, and identify a second character using character recognition based on the acquired one or more paths, and

input the first or second character in the input window.
