Abstract

Embodiments of the present invention disclose a user interface for facilitating touch input. According to one example, a single desired character is determined upon a touch input being received within at least one area of the user interface. The desired character is appended to an input word string. Furthermore, the input word string and a single desired character are displayed in distinct adjacent areas on the user interface.

Claims

1. A method for facilitating input on a touch-enabled device, the method comprising:

receiving a touch drawing input within at least one area of a graphical user interface displayed on the device;

determining a given character corresponding to the received touch drawing input;

displaying the given character in a first area of the graphical user interface;

receiving a touch gesture input in the graphical user interface;

in response to the touch gesture input, manipulating the given character displayed in the first area, to form a different target character, wherein the manipulating comprises;

changing the given character to a next character sequentially following the given character, in response to the touch gesture input being along a first direction, and

changing the given character to a previous character sequentially before the given character, in response to the touch gesture input being along a second direction different from the first direction;

displaying the target character in the first area of the graphical user interface;

appending the target character to an input word string; and

displaying the input word string in a second area adjacent to the first area of the graphical user interface, wherein the first area is separate and distinct from the second area.

2. The method of claim 1, further comprising:

predicting at least one word based on the input word string;

selectively displaying the predicted at least one word in a third area adjacent to the first area of the graphical user interface,

wherein the predicted at least one word is displayed after multiple characters have been input by the user.

3. The method of claim 2, further comprising:

analyzing the touch drawing input received in the first area to determine the given character.

4. The method of claim 2, wherein the touch gesture input is received within a fourth area of the graphical user interface.

5. The method of claim 2, wherein the predicted at least one word is displayed in the third area prior to the user completing entry of all characters for a target word.

6. The method of claim 5, wherein the third area includes a plurality of predicted words predicted based on the input word string.

7. The method of claim 1, wherein the touch drawing input is received without a virtual keyboard in the graphical user interface.

8. The method of claim 1, wherein the manipulating comprises:

changing the given character to an upper case character in response to a second touch gesture input being along the first direction, and

changing the given character to a lower case character in response to the second touch gesture input being along the second direction different from the first direction.

9. A computing device comprising:

a processor;

a display unit coupled to the processor and to display a graphical user interface, wherein the graphical user interface comprises;

a touch input area to receive a touch drawing input from a user;

a character display area adjacent to the touch input area and to display a given character corresponding to the received touch drawing input;

a word display area adjacent to the character display area and to display a string of characters input by the user,

wherein the character display area is separate and distinct from the touch input area and the word display area, and

the processor is to;

detect a touch gesture input in the graphical user interface, and

in response to the touch gesture input, manipulate the given character displayed in the character display area, to form a different target character, and cause display of the target character in the character display area, wherein the string of characters include the target character, wherein the manipulating comprises;

changing the given character to a next character sequentially following the given character, in response to the touch gesture input being along a first direction, and

changing the given character to a previous character sequentially before the given character, in response to the touch gesture input being along a second direction different from the first direction.

10. The computing device of claim 9, wherein the graphical user interface further comprises:

a word predictor area adjacent to the character display area and to display at least one predicted word in response to receiving user input of at least two characters.

11. The computing device of claim 9, wherein the processor is to analyze the touch drawing input to determine the given character.

12. The computing device of claim 9, wherein the touch drawing input and the touch gesture input are received without a virtual keyboard in the graphical user interface.

13. The computing device of claim 9, wherein the manipulating comprises:

changing the given character to an upper case character in response to a second touch gesture input being along the first direction, and

changing the given character to a lower case character in response to the second touch gesture input being along the second direction different from the first direction.

14. A non-transitory computer readable storage medium storing executable instructions, which when executed by a processor, cause the processor to:

receive a touch drawing input in at least one area of a graphical user interface displayed on a portable electronic device;

display a given character, corresponding to the touch drawing input, in a first area of the graphical user interface;

receive a touch gesture input in the graphical user interface, and

in response to the touch gesture input, manipulate the given character displayed in the first area, to form a different target character, wherein the manipulating comprises;

changing the given character to a next character sequentially following the given character, in response to the touch gesture input being along a first direction, and

changing the given character to a previous character sequentially before the given character, in response to the touch gesture input being along a second direction different from the first direction;

append the target character to a word string, wherein the word string is displayed in a second area of the graphical user interface;

predict at least one word based on the word string; and

display the predicted at least one word in a third area adjacent to the second area of the graphical user interface,

wherein the first area is separate and distinct from the second area and the third area.

15. The non-transitory computer readable storage medium of claim 14, wherein the receiving of the touch drawing input and the touch gesture input is performed without using a virtual keyboard in the graphical user interface.

16. The non-transitory computer readable storage medium of claim 14, wherein the manipulating comprises:

changing the given character to an upper case character in response to a second touch gesture input being along the first direction, and

changing the given character to a lower case character in response to the second touch gesture input being along the second direction different from the first direction.
