Abstract

A graphical user interface in the form of a transparent keyboard may be positioned over an existing computer display. The user may input textual data through the keyboard by selecting keys in the transparent keyboard display. The text entry may then appear on the computer display in non-transparent or conventional format.

Claims

1. A method comprising:

generating a text entry user interface on a computer screen;

generating a transparent keyboard interface on said computer screen, said interface including key images;

overlying said transparent keyboard interface over said text entry user interface;

enabling a user to enter data in the text entry user interface element using said transparent keyboard interface;

changing the focus between said text entry user interface and said transparent keyboard interface in response to user activation of a user selectable element; and

recognizing key selections made through said transparent keyboard interface when focus is on the transparent keyboard interface.

2. The method of claim 1 including generating a textual display on said computer screen and overlaying said transparent keyboard interface over said textual display.

3. The method of claim 1 wherein recognizing key selections includes recognizing contact with a touch screen.

4. The method of claim 1 wherein recognizing key selections includes recognizing pointing device selections of key images associated with said transparent keyboard interface.

5. The method of claim 1 including selectively enabling information to be entered through said transparent keyboard interface or another interface.

6. The method of claim 5 including providing a user selectable element to enable the user to select whether data is entered through said transparent keyboard interface or another interface.

7. An article comprising a medium storing instructions that enable a processor-based system to:

generate a text entry user interface element on a computer screen;

generate a transparent keyboard interface on said computer screen, said interface including key images;

in response to the detection of the activation by a user of a user selectable element, change the focus between said text entry user interface element and said transparent keyboard interface; and

recognize key selections made through said transparent keyboard interface only when focus is on said transparent keyboard interface.

8. The article of claim 7 further storing instructions that enable the processor-based system to generate a textual display on said computer screen and overlay said transparent keyboard interface over said textual display.

9. The article of claim 7 further storing instructions that enable the processor-based system to recognize contact with a touch screen.

10. The article of claim 7 further storing instructions that enable the processor-based system to recognize pointing device selections of key images associated with said transparent keyboard interface.

11. The article of claim 7 further storing instructions that enable the processor-based system to selectively enable information to be entered through said transparent keyboard interface or another interface.

12. The article of claim 11 further storing instructions that enable the processor-based system to provide a user selectable element to enable the user to select whether data is entered through said transparent keyboard interface or another interface.

13. A system comprising:

a processor-based device; and

a storage coupled to said processor-based device, said storage storing instructions that enable the processor-based device to generate a text entry user interface on a computer screen, generate a transparent keyboard interface on said computer screen, said interface including key images, recognize a user selection of said text entry user interface or said transparent keyboard interface, change focus between said transparent keyboard interface and said text entry user interface element in response to said user selection, and recognize key selections made through said transparent keyboard interface only when the user has selected the transparent keyboard interface for text entry.

14. The system of claim 13 including a display screen.

15. The system of claim 14 including a pointing device coupled to said processor-based device.
