Browser navigation for devices with a limited input system

摘要

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.
