Abstract

A device includes a memory to store multiple instructions, a touch-sensitive display, and a processor. The processor executes instructions in the memory to present, on the touch-sensitive display, an application display window; detect a touch on the application display window; display a handwriting input window based on the touch on the application display window, where the handwriting input window includes a magnified view of a portion of the application display window and where the handwriting input window is substantially centered at the location of the touch; detect a touch path input within the handwriting input window; display the touch path input within the handwriting input window; recognize that the touch path input has been removed from the handwriting input window; and present, on the touch-sensitive display, the application display window including the displayed touch path input, after the handwriting input window has been removed.

Claims

1. A computing-device implemented method, comprising:

detecting, by the computing device, a touch within an application display window on a surface of a touch screen of the computing device;

displaying, by the computing device, a handwriting input window based on the touch within the application display window, the handwriting input window including an enlarged view of a portion of the application display window;

receiving, on the surface of the touch screen, a touch path input within the handwriting input window;

recognizing, by the computing device, that the touch path input has been removed from the handwriting input window;

determining, by the computing device, that the touch path input has been removed for a time period exceeding a particular touch removal interval; and

displaying, on the touch screen, the application display window including the touch path input, after the handwriting input window has been removed.

2. The computing device-implemented method of claim 1, further comprising:

receiving a command to activate a text-entry mode, the command including one of;

user input via a control button, or

user input via the touch screen.

3. The computing device-implemented method of claim 1, further comprising:

determining, by the computing device, a location of the touch on the surface of the touch screen, where the displaying a handwriting input window is based on the location of the touch on the surface of the touch screen.

4. The computing device-implemented method of claim 1, further comprising:

determining that panning of the handwriting input window is required based on a last location of the touch path input.

5. The computing device-implemented method of claim 1, where the touch screen is a capacitive touch screen.

6. The computing device-implemented method of claim 1, further comprising:

converting the touch path input to digital text.

7. The computing device-implemented method of claim 1, where the application display window includes a background that is enlarged proportionately with the portion of the application display window.

8. The computing device-implemented method of claim 1, further comprising:

applying smoothing logic to the touch path input to provide a more visually pleasing result.

9. The computing device-implemented method of claim 1, where the enlarged view of the portion of the application display window provides magnification to enable fingertip text entry by a user.

10. The computing device-implemented method of claim 9, where the enlarged view of the portion of the application display window is magnified at least 400 percent of an original size for objects in the application display window.

11. A device, comprising:

a memory to store a plurality of instructions;

a touch-sensitive display; and

a processor to execute instructions in the memory to;

present, on the touch-sensitive display, an application display window,

detect a touch on the application display window,

display a handwriting input window based on the touch on the application display window, where the handwriting input window includes a magnified view of a portion of the application display window and where the handwriting input window is substantially centered at the location of the touch,

detect a touch path input within the handwriting input window,

display the touch path input within the handwriting input window,

recognize that the touch path input has been removed from the handwriting input window, and

present, on the touch-sensitive display, the application display window including the displayed touch path input, after the handwriting input window has been removed.

12. The device of claim 11, where the processor further executes instructions in the memory to:

determine that the touch path input has been removed for a time period exceeding a particular touch removal interval.

13. The device of claim 11, where the processor further executes instructions in the memory to:

detect a location of the touch path input;

determine that panning of the handwriting input window is required based on the location of the touch path input; and

center the handwriting input window based on a projected next touch path input location.

14. The device of claim 13, where the enlarged view of the portion of the application display window provides magnification to enable fingertip text entry by a user.

15. The device of claim 11, where the processor further executes instructions in the memory to:

activate a text-entry mode for the application display window, where the text entry mode enables automatic magnification of a portion of the application display window when the touch is detected on the application display window.

16. The device of claim 11, where the application display window includes an interface for:

a Multimedia Messaging Service (MMS) application,

an email application,

a word processing application,

a game application,

an image-viewing application,

a document-viewing application,

a map application,

a desktop note application, or

a text message application.

17. The device of claim 11, where the handwriting input window includes one or more of:

a magnification control,

a character recognition tools,

a display lock, or

a panning control.

18. The device of claim 11, where the processor further executes instructions in the memory to:

convert the touch path input to digital text.

19. A device, comprising:

means for initiating a text entry mode to accept fingertip text entry;

means for detecting a touch within an application display window of a touch screen;

means for displaying a handwriting input window based on the touch within the application display window, the handwriting input window including an enlarged view of a portion of the application display window;

means for receiving a touch path input within the handwriting input window;

means for recognizing removal of the touch path input;

means for removing the display of the handwriting input window; and

means for displaying the application display window including the touch path input, after the display of the handwriting input window has been removed.

20. The device of claim 19, further comprising:

means for displaying the touch path input within the handwriting input window.
