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. An electronic device comprising:

a touch screen; and

a controller configured to;

provide a user interface on the touch screen having an input window and a keyboard,

detect whether a touch input is started from the keyboard or a region outside the keyboard,

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

in response to detecting the touch input starting from the region outside the keyboard, 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.

2. The electronic device of claim 1, wherein the controller is configured to maintain a form of the keyboard while a handwriting input mode is enabled.

3. The electronic device of claim 1, wherein the controller is configured to maintain a character key of the keyboard while the text input mode is disabled.

4. The electronic device of claim 1, wherein the controller is configured to, in response to detecting the touch input starting from the region outside an English keyboard,

disable the text input mode through the English keyboard,

recognize a Chinese character as the second character using character recognition based on the acquired one or more paths, and

enable the text input mode to receive another touch input corresponding to at least one key of the English keyboard after the inputting of the second character.

5. The electronic device of claim 1, wherein the controller is configured to determine a range or position of the touch input in the region outside the keyboard.

6. The electronic device of claim 1, wherein the controller is configured to determine an entire display area of the touch screen as the region for character recognition.

7. An electronic device, comprising:

a touch screen; and

a processor configured to;

provide a user interface on the touch screen having an input window and a keyboard,

in response to a touch input starting from a region outside the keyboard, enable a handwriting input mode and disable a text input mode through the keyboard to allow the touch input to extend into the keyboard,

while in the handwriting input, acquire one or more paths of the touch input, and identify a first character using character recognition based on the acquired one or more paths, and

input the first character in the input window.

8. The electronic device of claim 7, wherein, after the first character is identified, the processor is configured to disable the handwriting input mode and enable the text input mode through the keyboard, and

while the text input mode through the keyboard is enabled, and in response to a touch input starting from the keyboard, the processor is configured to identify a second character on the keyboard that corresponds to the touch input, and input the second character in the input window.

9. The electronic device of claim 7, wherein the processor is configured to maintain an image of the keyboard while the handwriting input mode is enabled.

10. The electronic device of claim 7, wherein the processor is configured to use both an area of the keyboard and the region outside the keyboard of the touch screen as a region for receiving one or more paths of the touch input for character recognition.
