Inputting radical on touch screen device

1. A computer-readable storage medium storing computer-executable instructions that, based on execution by a computer, configure the computer to:

display, on a touch screen device, a first soft key labeled with a first label, the first label representing a portion of a radical;

accept a touch input associated with the soft key, the touch input corresponding to at least one of, a double tap, a press and hold, a flick, an expand gesture, or a contract gesture; and

select an action for the touch screen device to perform based, at least in part, on the first label, a state associated with a set of radical stroke input rules, and the touch input, where the action is at least one of:

inputting the radical into a radical data store; and

updating a set of complete radicals displayed on the touch screen device by a radical picker,

the set of radical stroke input rules controlling at least one of, a number of strokes used to form a radical, an order of strokes used to form a radical, or a position of a stroke used to form a radical, and

the state being defined by at least one of, a current number of strokes associated with inputting a current radical, a current order of strokes associated with inputting the current radical, or a current position of strokes associated with inputting the current radical.

2. The computer-readable storage medium of claim 1 , where the first label is a single stroke associated with the radical.

3. The computer-readable storage medium of claim 2 , where the single stroke is one of, a Chinese one stroke, a Chinese line stroke, a Chinese dot stroke, a Chinese slash stroke, a Chinese second stroke and a Chinese hook stroke.

4. The computer-readable storage medium of claim 1 , where the first label is a subset of a set of strokes associated with the radical.

5. The computer-readable storage medium of claim 1 , where the radical is one of, a Chinese radical, a Japanese radical and a Korean radical.

6. The computer-readable storage medium of claim 1 , where the computer-executable instructions configure the computer to control the touch screen device to display a second soft key with a second label having more strokes than the first label upon detecting the expand gesture.

7. The computer-readable storage medium of claim 1 , where the computer-executable instructions configure the computer to control the touch screen device to display a second soft key with a second label having fewer strokes than the first label upon detecting the contract gesture.

8. The computer-readable storage medium of claim 1 , where the computer-executable instructions configure the computer to:

control the touch screen device to label the first soft key with the first label; and

control the touch screen device to selectively re-label the first soft key with a second label.

9. The computer-readable storage medium of claim 1 , where the computer-executable instructions configure the computer to control one or more of, a smart phone, a tablet computer, a laptop computer, an appliance, a personal digital assistant, a game device, and a television to display the first soft key.

10. A computer-readable storage medium storing computer-executable instructions that, based on execution by a computer configure the computer to:

access a set of displayable Chinese radicals stored in a radical data store associated with a touch screen apparatus;

access a set of displayable strokes stored in a stroke data store associated with the touch screen apparatus;

select, from the set of displayable strokes, a subset of displayable strokes to display on the touch screen apparatus;

select, from the set of displayable Chinese radicals, a subset of displayable Chinese radicals to display on the touch screen apparatus;

display the subset of displayable strokes on a first portion of the touch screen apparatus while also displaying the subset of displayable Chinese radicals on a second portion of the touch screen apparatus;

receive a touch input associated with a member of the subset of displayable strokes or a member of the subset of displayable Chinese radicals, the touch input corresponding to at least one of an expand gesture or a contract gesture; and

control the touch screen apparatus to perform an action based, at least in part, on the touch input and a state associated with a set of radical stroke input rules, the action at least corresponding to:

based at least on a determination that the touch input is the expand gesture, controlling the touch screen apparatus to display a soft key with a label having more strokes than the member of the subset of displayable strokes; or

based at least on a determination that the touch input is the contract gesture, controlling the touch screen apparatus to display a soft key with a label having fewer strokes than the member of the subset of displayable strokes.

11. An apparatus, comprising:

a processor;

memory;

a touch screen;

a set of logics configured to control input of Chinese radicals; and

an interface configured to operationally couple the processor, the memory, the touch screen, and the set of logics;

the set of logics comprising:

a first logic that is configured to control the apparatus to display on the touch screen one or more selected strokes associated with one or more selected Chinese radicals;

a second logic that is configured to control the apparatus to display on the touch screen one or more selected Chinese radicals; and

a third logic that is configured to control the first logic and the second logic based, at least in part, on an input detected on the touch screen,

the third logic controlling the first logic to select strokes to display based, at least in part, on a previously displayed stroke,

the third logic controlling the second logic to select Chinese radicals to display based, at least in part, on the previously displayed stroke and a state associated with a set of radical stroke input rules, and

the set of radical stroke input rules describing at least one of a number of strokes used to form a radical, an order of strokes used to form a radical, or a position of a stroke used to form a radical.

12. The apparatus of claim 11 , the third logic being configured to input a Chinese radical into a radical data store in the memory based on the input detected on the touch screen.

13. The apparatus of claim 12 , the input detected on the touch screen being one of, a flick gesture, a press and hold, a double tap, a drag and drop, an expand gesture, and a contract gesture.

14. The apparatus of claim 13 , comprising a communication circuit that receives, from an external source, one or more of, a stroke to display, a radical to display, a radical to input, and a decision concerning a radical to input.

15. The computer-readable storage medium of claim 1 , wherein the radical comprises a plurality of strokes having a fixed stroke sequence and is shared by at least two characters.
