Abstract

A system and method is disclosed that provides for progressively displaying sequential pages on a handheld electronic device for user viewing. The system and method provides for displaying a first page of a plurality of sequentially linked pages on a display screen of a handheld electronic device, and displaying two navigation icons on the display screen of the handheld electronic device together with the first page, one of said two navigation icons signifying the previous page to the first page and acting as a user-actuable link thereto when a previous page exists and the other of said two navigation icons signifying the next page to the first page and acting as a user-actuable link thereto when a next page exists. The system and method further provide for scrolling toward a bottom of the first page until a lower boundary of the first page is reached and upon reaching said lower boundary, the navigation icon signifying the next page being automatically designated for user actuation.

Claims

1. A method for progressively displaying sequential pages on a handheld electronic device for user viewing, said method comprising:

displaying a first page of a plurality of sequentially linked pages on a display screen of a handheld electronic device;

displaying two navigation icons on the display screen of the handheld electronic device together with the first page, one of said two navigation icons signifying the previous page to the first page and acting as a user-actuable link thereto when a previous page exists and the other of said two navigation icons signifying the next page to the first page and acting as a user-actuable link thereto when a next page exists; and

scrolling toward a bottom of the first page until a lower boundary of the first page is reached and upon reaching said lower boundary, the navigation icon signifying the next page being automatically designated for user actuation.

2. The method of claim 1, further comprising actuating the designated navigation icon signifying the next page and thereby causing the next page to be displayed for user viewing.

3. The method of claim 1, further comprising affecting scrolling of the first page utilizing an auxiliary user input device on the handheld electronic device.

4. The method of claim 2, further comprising actuating the designated navigation icon signifying the next page by depressing an auxiliary user input device on the handheld electronic device.

5. The method of claim 3, wherein the auxiliary user input device is a trackball.

6. The method of claim 4, wherein the auxiliary user input device is a trackball.

7. The method of claim 1, wherein the handheld electronic device is a wireless handheld communication device that transmits data to, and receives data from a communication network utilizing radio frequency signals.

8. The method of claim 1, wherein the handheld electronic device is sized to be cradled in the palm of a user'"'"'s hand.

9. The method of claim 1, wherein the handheld electronic device further comprises a keyboard suitable for accommodating textual input to the handheld electronic device and an auxiliary user input device located essentially between the keyboard and the display screen of the handheld electronic device.

10. A handheld electronic device programmed to progressively display sequential pages on a handheld electronic device for user viewing, said handheld electronic device comprising:

an auxiliary user input device;

a display screen displaying a first page of a plurality of sequentially linked pages together with two navigation icons, one of said two navigation icons signifying the previous page to the first page and acting as a user-actuable link thereto when a previous page exists and the other of said two navigation icons signifying the next page to the first page and acting as a user-actuable link thereto when a next page exists; and

a microprocessor having a control program associated therewith for controlling operation of said handheld electronic device, said control program configured to process user input requests wherein said user input requests comprise scrolling toward a bottom of the first page, using said auxiliary user input device, until a lower boundary of the first page is reached and upon reaching said lower boundary, the navigation icon signifying the next page is automatically designated for user actuation.

11. The handheld electronic device of claim 10, wherein said control program is further configured to process a request that the navigation icon signifying the next page be actuated and thereby causing the next page to be displayed for user viewing.

12. The handheld electronic device of claim 11, wherein the auxiliary user input device is depressible and depressing the auxiliary user input device requests that the navigation icon signifying the next page be actuated.

13. The handheld electronic device of claim 10, wherein the auxiliary user input device is a trackball.

14. The handheld electronic device of claim 12, wherein the auxiliary user input device is a trackball.

15. The handheld electronic device of claim 10, wherein the handheld electronic device is a wireless handheld communication device that transmits data to, and receives data from a communication network utilizing radio frequency signals.

16. The handheld electronic device of claim 10, wherein the handheld electronic device is sized to be cradled in the palm of a user'"'"'s hand.

17. The handheld electronic device of claim 10, wherein the handheld electronic device further comprises a keyboard suitable for accommodating textual input to the handheld electronic device and an auxiliary user input device located essentially between the keyboard and the display screen of the handheld electronic device.

18. A processing subsystem configured to be installed in a handheld electronic device comprising a user interface including a display screen and an auxiliary user input device, said processing subsystem comprising:

operating system software that controls the operation of an incorporating handheld electronic device and said operating software is programmed to control operation of said handheld electronic device, said operating system is configured to progressively display sequential pages on a handheld electronic device for user viewing, wherein said progressively displaying sequential pages on a handheld electronic device for user viewing comprises;

displaying a first page of a plurality of sequentially linked pages on a display screen of a handheld electronic device;

displaying two navigation icons on the display screen of the handheld electronic device together with the first page, one of said two navigation icons signifying the previous page to the first page and acting as a user-actuable link thereto when a previous page exists and the other of said two navigation icons signifying the next page to the first page and acting as a user-actuable link thereto when a next page exists; and

scrolling toward a bottom of the first page until a lower boundary of the first page is reached and upon reaching said lower boundary, the navigation icon signifying the next page being automatically designated for user actuation.
