Abstract

A method and a system for navigating a display screen to search for a desired item of information stored in an electronic device. The electronic device includes a novel fly over user interface (FOUI) capable of receiving commands from a user to provide a zoom out view of the display screen. A user may commence a navigation session by touching the display screen in a non active area or by clicking on a specifically designated icon to activate the user interface. During the navigation session, the display screen is zoomed-out and a magnifying area may appear on the display screen. The user interface enables the user to scroll the zoomed-out display screen by dragging the magnifying area towards an edge of the display screen to find a desired item of information. The display screen may be a display screen of a digital device (e.g., portable computer, personal computer, a cellular telephone, a digital watch, etc). The user may terminate a navigation session by removing the pointer from the display screen.

Claims

1. A method for implementing a touchscreen user interface for a device, the method comprising the steps of:

a) displaying a plurality of items in a normal mode on a touchscreen of a portable electronic device;

b) registering a user input to enter a fly over mode;

c) in response to b), providing a fly over area within the touchscreen, wherein the fly over area provides a modified view of items within the fly over area with respect to items outside the fly over area, wherein all the items outside the fly over area are zoomed out with respect to the items in the normal mode and the ones of the items outside the fly over area are shrunk with respect to the items in the normal mode; and

d) controlling a location of the fly over area with respect to the touchscreen in accordance with a movement command received from a user.

2. The method of claim 1 further comprising:

scrolling a display content of the touchscreen when the fly over area reaches an edge of the touchscreen.

3. The method of claim 1 wherein the movement command for controlling the location of the fly over area with respect to the touchscreen comprises a user dragging a navigation pointer across the touchscreen.

4. The method of claim 3 wherein the navigation pointer is a stylus.

5. The method of claim 1 further comprising:

exiting the fly over mode when the user stops controlling the location of the fly over area.

6. A computer readable memory having computer readable instructions for implementing a touchscreen user interface for a device, the instructions when executed by a computer processor of the device causes the device to implement a method comprising the steps of:

a) displaying a plurality of items in a normal mode on a touchscreen of a portable electronic device;

b) registering a user input to enter a fly over mode;

c) in response to b), providing a fly over area within the touchscreen, wherein the fly over area provides a modified view of items within the fly over area with respect to items outside the fly over area, wherein all the items outside the fly over area are zoomed out with respect to the items in the normal mode and the ones of the items outside the fly over area are shrunk with respect to the items in the normal mode; and

d) controlling a location of the fly over area with respect to the touchscreen in accordance with a movement command received from a user.

7. The computer readable memory of claim 6 further comprising the step of scrolling a display content of the touchscreen when the fly over area reaches an edge of the touchscreen.

8. The computer readable memory of claim 6 wherein the movement command for controlling the location of the fly over area with respect to the touchscreen comprises a user dragging a navigation pointer across the touchscreen.

9. The computer readable memory of claim 6 further comprising the step of exiting the fly over mode when the user stops controlling the location of the fly over area.

10. The computer readable memory of claim 6 wherein the navigation pointer is a stylus.

11. A system for implementing a touchscreen user interface for a device, the system comprising:

a) means for displaying a plurality of items in a normal mode on a touchscreen of a portable electronic device;

b) means for registering a user input to enter a fly over mode;

c) means for, in response to b), providing a fly over area within the touchscreen, wherein the fly over area provides a modified view of items within the fly over area with respect to items outside the fly over area, and wherein all items outside the fly over area are zoomed out with respect to the items in the normal mode and the ones of the items outside the fly over area are shrunk with respect to the items in the normal mode; and

d) means for controlling a location of the fly over area with respect to the touchscreen in accordance with a movement command received from a user.

12. The system of claim 11 further comprising means for scrolling a display content of the touchscreen when the fly over are reaches an edge of the touchscreen.

13. The system of claim 11 wherein the movement command for controlling the location of the fly over area with respect to the touchscreen comprises a user dragging a navigation pointer across the touchscreen.

14. The system of claim 11 further comprising means for exiting the fly over mode when the user stops controlling the location of the fly over area.

15. The system of claim 11 wherein the navigation pointer is a stylus.

16. A method for implementing a touchscreen user interface of a device, the method comprising:

initiating a fly over mode on a touchscreen user interface of a device providing a fly over area within the touchscreen;

initiating a first session using the fly over area to display a plurality of items on the touchscreen, the plurality of items including an icon representing one or more addresses;

initiating a second session using the fly over area to display a list of streets on the touchscreen upon activation of the icon by a user of the device;

initiating a third session using the fly over area to display a view of a section of a map upon selection of a street in the list of streets by the user, the section of the map including a geographical location of the street selected by the user; and

wherein the fly over area provides a view of the plurality of items, list of streets, and the section of the map wherein all items outside the fly over area are zoomed out and shrunken with respect to the items within the fly over area.

17. A computer readable memory having computer readable instructions for implementing a touchscreen user interface for a device, the instructions when executed by a processor of the device causes the device to implement a method comprising the steps of:

initiating a fly over mode on a touchscreen user interface of a device providing a fly over area within the touchscreen;

initiating a first session using the fly over area to display a plurality of items on the touchscreen, the plurality of items including an icon representing one or more addresses;

initiating a second session using the fly over area to display a list of streets on the touchscreen upon activation of the icon by a user of the device;

initiating a third session using the fly over area to display a view of a section of a map upon selection of a street in the list of streets by the user, the section of the map including a geographical location of the street selected by the user; and

wherein the fly over area provides a view of the plurality of items, list of streets, and the section of the map wherein all items outside the fly over area are zoomed out and shrunken with respect to the items within the fly over area.

18. A system for implementing a touchscreen user interface for a device, the system comprising:

means for initiating a fly over mode on a touchscreen user interface of a device providing a fly over area within the touchscreen;

means for initiating a first session to display a plurality of items on the touchscreen, the plurality of items includes an icon representing one or more addresses;

means for initiating a second session to display a list of streets on the touchscreen upon activation of the icon by a user of the device; and

means for initiating a third session to display a view of a section of a map upon selection of a street in the list of streets by the user, the section of the map including a geographical location of the street selected by the user; and

wherein the fly over area provides a view of the plurality of items, list of streets, and the section of the map wherein all items outside the fly over area are zoomed out and shrunken with respect to the items within the fly over area.
