Abstract

Methods, system, and computer program products for browsing content with a display area and input system that may be limited in comparison to more traditional browsing systems. Movement between and selection of interactive elements generally occurs in a navigation mode, whereas interaction with a single interactive element generally occurs in an edit mode. In navigation mode, a direction input selects the next interactive element in the direction indicated. If no interactive element is at least partially visible in the direction indicated or if a selected interactive element is only partially visible, the display scrolls. Switching between navigation mode and edit mode is based on the input received, in view of the input supported, by a particular interactive element. Interactive elements may be limited to the width of available display area.

browsing with the wireless telephone or personal digital assistant in edit mode; and

switching from edit mode to navigation mode upon receiving the direction input.

7. A computer program product as recited in claim 1, wherein the interactive element is part of form content that does not include a submit element, the method further comprising the acts of:

browsing with the wireless telephone or personal digital assistant in edit mode; and

submitting the form content upon receiving an action input.

8. A computer program product as recited in claim 1, wherein the interactive element is capable of representing two states, the method further comprising an act of switching from one state to the other upon receiving an action input while in navigation mode.

9. A computer program product as recited in claim 1, wherein the interactive element comprises a link, the method further comprising an act of following the link upon receiving an action input.

10. A computer program product as recited in claim 1, wherein the interactive element exceeds the width of available wireless telephone or personal digital assistant display area, the method further comprising an act of adjusting the width of the interactive element to be less than or equal to the width of available wireless telephone or personal digital assistant display area.

11. A computer program product as recited in claim 1, wherein the interactive element is only partially visible in the wireless telephone or personal digital assistant display area, the method further comprising acts of:

adjusting the width of the interactive element to be less than or equal to the width of available wireless telephone or personal digital assistant display area if the width of the interactive element exceeds the width of available wireless telephone or personal digital assistant display area; and

scrolling the wireless telephone or personal digital assistant display area until the interactive element is completely visible.

12. A computer program product as recited in claim 1, wherein the selected interactive element is a previously selected interactive element, the method further comprising the acts of:

receiving a subsequent direction input that corresponds to scrolling the wireless telephone or personal digital assistant display area, the subsequent direction input being generated by activating a navigation key;

while the subsequent direction input is being received, if less than all of the content is displayed and no other interactive element is at least partially visible in the direction of the subsequent direction input, scrolling the display of the content in the direction of the subsequent direction input;

selecting a next interactive element that is at least partially visible, the selection being based on the subsequent direction input relative to the previously selected interactive element;

removing highlighting from the previously selected interactive element to indicate that the previously selected interactive element is no longer selected; and

highlighting the next interactive element to indicate that the next interactive element is selected.

13. A computer program product for use in either a wireless telephone or personal digital assistant configured for browsing content received from a content source, and having a display area and input system that is limited as compared to pointing devices and displays often found in more traditional browsing systems, and wherein one or more interactive elements within content received from the content source may behave differently in a browsing context than the one or more interactive elements behave in an operating system shell context, the computer program product comprising one or more computer-readable storage media having stored computer-executable instructions for implementing a method of browsing content that includes one or more interactive elements, wherein the browsing includes an edit mode and a navigation mode, the method comprising steps for:
