The invention relates to presenting and browsing in metadata on handheld display devices such as music/mp3 players, mobile phones, PDA's, digital cameras. A graphical user interface (GUI) accesses metadata arranged in different categories and determines a hierarchical order of this. A metadata category is shown in a menu of category entries in a separate pane on the GUI. Rotation of the device is detected by a rotation sensor, and upon rotation the pane with the menu being browsed before rotation is maintained in the GUI, and at least one pane a menu representing a hierarchical super- or sub-category of the category being browsed before rotation is added or removed. This allows the user to expand or collapse metadata categories shown in the GUI by rotating the device. |
