Portable Terminal Folder Display via Touch-Driven 3D Stacking

The patent introduces a third dimension for information display by stacking folder icons vertically to represent directory depth. Instead of requiring users to navigate through multiple screens or perform sequential clicking operations, the folder hierarchy is visualized in 3D space where depth is represented by vertical stacking. Users can directly access sub-folders by touching the stacked folder icons, reducing navigation steps from multiple clicks to single touch operations while maintaining portability.

The patent segments the display area into multiple regions showing different folder levels simultaneously. Rather than displaying one folder level at a time, the interface divides the screen to show parent folders and sub-folders in separate stacked groups, allowing users to overview the entire folder structure and select desired content without sequential navigation through each level.

The patent implements a nested display structure where sub-folders are visually contained within or stacked upon parent folder icons. Each folder level is nested within the previous level's visual representation, creating a compact hierarchical structure that fits entire directory trees within limited screen space. This nesting approach displays complete folder hierarchies without requiring additional screens or complex multi-page interfaces.

The patent resolves information completeness vs. display complexity by adding a vertical dimension to represent folder depth. Instead of spreading folder contents across multiple horizontal screens, the hierarchy extends vertically with stacked icons showing parent-child relationships. This dimensional transformation allows complete folder structure visualization in a single screen view without increasing interface complexity.
