<P>PROBLEM TO BE SOLVED: To provide information on contents without cluttering a display screen. <P>SOLUTION: Provided is an information processor, including: a display format selection control section that selects a display format for displaying on a display screen both at least a part of a feature space prescribed based on a predetermined feature quantity and a set of content data associated with positional information representing a position in the feature space as metadata; and a node selecting section that uses a prescribed tree structure having the content data as leaf nodes to select a node which satisfies predetermined conditions from the nodes included in the tree structure in accordance with the size of a displayed feature space. The node selecting section selects, from the nodes positioned outside of the displayed feature space, a node as an exo-display screen node, which has a largeness in the feature space corresponding to a separation distance from the displayed feature space of the relevant node. The display format selection control section causes an object which indicates the existence of the selected exo-display screen node to be displayed within the display screen. <P>COPYRIGHT: (C)2013,JPO&INPIT |
