Abstract

Virtual Focus allows a user to explore elements on a screen without changing the location of the current system focus. While virtually navigating around and exploring the user interface (UI) elements on the screen, the user may change the system'"'"'s input focus to the current virtual focus or return to the current system focus position. The user may also choose between navigation modes such as tree navigation and spatial navigation. Virtual focus navigation also allows the user to locate elements on the screen that may not be navigated to using just the keyboard input focus. Additionally, while using virtual focus to navigate around a screen, the state of user interface elements remains constant.

Claims

1. A computer-implemented method of navigating using a virtual focus, comprising:

entering a virtual focus navigation mode;

receiving an input that directs a virtual focus location to change;

updating the virtual focus location to change in response to the input;

wherein a system focus location is maintained while in the virtual focus navigation mode;

determining an element that currently has the virtual focus; and

providing information about the element that currently has the virtual focus.

2. The method of claim 1, wherein providing the information about the element comprises performing at least one of:

providing a name of the element;

providing a description of the element;

highlighting the element and magnifying the element.

3. The method of claim 1, wherein providing the information about the element comprises invoking a command and providing information relating to the invocation of the command;

wherein invoking the command maintains a current state of the element while in the virtual focus navigation mode.

4. The method of claim 1, wherein entering the virtual focus navigation mode comprises selecting between a tree navigation mode and a spatial navigation mode.

5. The method of claim 4, wherein navigating in the tree navigation mode comprises moving from element to element in response to a received input.

6. The method of claim 4, wherein spatial navigation comprises receiving the input to direct the virtual focus location to change through at least one of:

a keypad;

a keyboard; and

a voice input.

7. The method of claim 2, further comprising adjusting the system focus location to the virtual focus location.

8. The method of claim 2, further comprising exiting the virtual focus navigation mode and returning to a system focus mode;

wherein returning to the system focus mode changes the location of the virtual focus to the location of the system focus.

9. A computer-readable medium having computer-executable instructions for navigating an application using virtual focus, comprising:

updating a virtual focus location in response to an input;

wherein a system focus location is maintained while the virtual focus location changes;

determining when an element has a virtual focus in response to a comparison between the virtual focus location and a location of the element; and

providing information about the element.

10. The computer-readable medium of claim 9, wherein providing the information about the element comprises performing at least one of:

providing a name of the element;

providing a description of the element;

highlighting the element and magnifying the element.

11. The computer-readable medium of claim 9, further comprising invoking a command on the element;

providing information in response to the invocation of the command; and

maintaining a state of the element before the command was invoked.

12. The computer-readable medium of claim 9, wherein entering the virtual focus navigation mode comprises entering a tree navigation mode, wherein navigating in the tree navigation mode comprises moving from element to element in response to a received input.

13. The computer-readable medium of claim 12, wherein entering the virtual focus navigation mode comprises entering a spatial navigation mode wherein navigating in the spatial navigation mode comprises receiving the input to direct the location of the virtual focus to change through at least one of:

a keypad;

a keyboard; and

a voice input.

14. The computer-readable medium of claim 10, further comprising receiving a command to change the system focus location to the virtual focus location upon and changing the system focus location to the virtual focus location in response to the command.

15. The computer-readable medium of claim 10, further comprising exiting the virtual focus navigation mode and returning to a system focus mode upon a window change.

16. A system for navigating an application using a virtual focus navigation mode, comprising:

an application having elements;

an input component configured to receive input;

an output component configured to provide information;

wherein providing the information comprises performing at least one of;

providing a name of an element;

providing a description of an element;

highlighting an element and magnifying an element;

a virtual focus manager that is coupled to the application and the input component and that is configured to;

enter the virtual focus navigation mode;

use the input to adjust a virtual focus location while maintaining a system focus location;

determining when an element within the application receives a virtual focus; and

when the element receives the virtual focus providing information about the element to the output device.

17. The system of claim 16, wherein providing the information about the element comprises invoking a command and providing information relating to the invocation of the command;

wherein invoking the command maintains a current state of the element while in the virtual focus navigation mode.

18. The system of claim 16, wherein entering the virtual focus navigation mode comprises entering a tree navigation mode, wherein navigating in the tree navigation mode comprises moving from element to element in response to a received input.

19. The system of claim 16, wherein entering the virtual focus navigation mode comprises entering a spatial navigation mode wherein navigating in the spatial navigation mode comprises receiving the input to direct the location of the virtual focus to change through at least one of:

a keypad;

a keyboard; and

a voice input.

20. The system of claim 16, further comprising changing the system focus location to the virtual focus location in response to a predetermined command.
