Navigation pattern on a directory tree
Navigation management occurs in a mobile device during a directory up-down scroll and it involves a user interface and a directory (e.g., mobile directory of photos). The directory is a tree-shaped hierarchy of nodes such that any node on the directory is selectable by a user via the user interface. This way navigation can flow up-down through the directory. Additionally, the navigation management involves associating a state and one or more action items with each node and saving the state. The state is an expanded or collapsed condition of the node. If the state of a particular node is expanded, additional nodes at a lower level of the hierarchy are presented to the user. If its state is collapsed only that particular node is presented and the other nodes are hidden. The user interface includes for any node selected by the user its associated one or more action items.
1. A method for managing navigation in mobile devices, comprising:
providing a user interface in a mobile device;
constructing a mobile photo album directory as a tree-shaped hierarchy of nodes;
providing the directory such that any node on the directory is selectable by a user via the user interface, whereby navigation can flow up-down through the directory;
associating a state and one or more action items with each node;
saving the state of each node, the state being an expanded or collapsed condition of the node, wherein if the state of a particular node is expanded additional nodes at a lower level of the hierarchy are presented to the user, otherwise if the state is collapsed only that particular node is presented and the other nodes are hidden; and
for a node selected by the user providing in the user interface the node's associated one or more action items in a menu, wherein the menu is displayable on the mobile device's screen as a pull-down menu or a pop-up menu, and
displaying a photo associated with the node selected by the user, wherein the photo is downloaded from a server onto the mobile device,
wherein the action items include save to mobile, email photo, thumbnails, online albums, home, or a combination thereof, and selection of an action item brings up a page that corresponds to the action item,
wherein selection of home causes display of a page having mobile album and online album options, wherein the mobile album is an album of photos stored locally on the mobile device, and the online album is an album of photos stored on the server,

program code for saving the state of each node, the state being an expanded or collapsed condition of the node, wherein if the state of a particular node is expanded additional nodes at a lower level of the hierarchy are presented to the user, otherwise if the state is collapsed only that particular node is presented and the other nodes are hidden; and
program code for providing in the user interface for a node selected by the user the node's associated one or more action items in a menu, wherein the menu is displayable on the mobile device's screen as a pull-down menu or a pop-up menu, and
displaying a photo associated with the node selected by the user, wherein the photo is downloaded from a server onto the mobile device,
wherein the action items include save to mobile, email photo, thumbnails, online albums, home, or a combination thereof, and selection of an action item brings up a page that corresponds to the action item,
wherein selection of home causes display of a page having mobile album and online album options, wherein the mobile album is an album of photos stored locally on the mobile device, and the online album is an album of photos stored on the server,
selecting online album allows the user to access and manipulate photo images that have been uploaded to the server, and
