Device and method for stroke based graphic input

1. A user interface comprising:

a touch screen adapted to receive stroke input,

wherein said user interface is configured to: a) display a graphical trace of said received stroke input on a display;

b) in an instance in which an input speed of the received stroke input is below a threshold value, recognize the received stroke input as coded characters and cause at least a portion of the graphical trace to be removed from the display; and

c) in an instance in which the input speed of said received stroke input is above the threshold value, cause the graphical trace to be stored in a memory of the user interface in a graphical form.

2. A user interface according to claim 1 , wherein said user interface is configured to remove at most a portion of said graphical trace in a first step and in a second step remove said graphical trace completely.

3. A user interface according to claim 1 wherein said portion of said graphical trace corresponds to a group of strokes.

4. A user interface according to claim 1 further configured to gradually remove said portion of said graphical trace to be removed before removing said portion completely.

5. A user interface according to claim 4 , wherein said faded display is achieved by displaying said portion to be removed with a lower intensity, as a dotted or segmented line, in a different color or as being shaded.

6. A user interface according to claim 1 , further configured to maintain said graphical trace stationary before removing said portion of said graphical trace.

7. A device comprising a user interface according to claim 1 .

8. A device according to claim 7 , wherein said device is a mobile communications terminal or a laptop computer or a drawing pad or a personal digital assistant.

9. An apparatus comprising:

at least one processor,

at least one memory including computer program code,

the at least one memory and the computer program instructions configured to, with the processor, cause the apparatus at least to:

receive a stroke input;

cause a graphical trace of the stroke input to be displayed on a display;

in an instance in which an input speed of said received stroke input is below a threshold value, recognize the received stroke input as coded characters and cause at least a portion of the graphical trace to be removed from the display; and

in an instance in which the input speed of said received stroke input is above the threshold value, cause the graphical trace to be stored in a memory of the user interface in a graphical form.

10. A method comprising:

receiving a stroke input;

causing a graphical trace of said stroke input to be displayed on a display;

in an instance in which an input speed of said received stroke input is below a threshold value, recognizing said received stroke input as coded characters and causing at least a portion of the graphical trace to be removed from the display; and

in an instance in which the input speed of said received stroke input is above the threshold value, causing the graphical trace to be stored in a memory of the user interface in a graphical form.

11. A computer program product comprising at least one non-transitory computer-readable storage medium having computer-executable program code instructions stored therein, the computer-executable program code instructions comprising program code instructions for:

receiving stroke input;

causing a graphical trace of said stroke input to be displayed on a display;

in an instance in which an input speed of said received stroke input is below a threshold value, recognizing said received stroke input as coded characters and causing at least a portion of the graphical trace to be removed from the display; and

in an instance in which the input speed of said received stroke input is above the threshold value, causing the graphical trace to be stored in a memory of the user interface in a graphical form.

12. The computer program product as in claim 11 , the computer-executable program code instructions further comprising program code instructions for fading said portion or gradually removing said graphical trace before removing it.
