DISPLAY SCREEN CONTROL METHOD, GRAPHICAL USER INTERFACE, INFORMATION PROCESSING APPARATUS, INFORMATION PROCESSING METHOD, AND PROGRAM
First Claim
1. A display screen control method, comprising the steps of:
- generating a tree structure in which a leaf node represents content data associated with position information, serving as metadata, representing a location of a feature space defined based on a predetermined feature quantity, and a set of nodes whose distance in the feature space satisfies a predetermined condition is defined as a parent node of the nodes satisfying the predetermined condition;
when any position information serving as a reference is specified, identifying a node in the tree structure to which the specified position information belongs;
extracting, according to a position of the identified node in the tree structure, one or a plurality of nodes, other than the node to which the reference position information belongs, from among the nodes in the tree structure; and
using a node extraction result obtained in the step of extracting the node to display an object corresponding to the content data at a position in a display screen according to the position information,wherein in the step of identifying the node and in the step of extracting the node, a position corresponding to a center of the display screen is used as the position information serving as the reference,in the step of displaying the object, in a case where there is content data in which a position corresponding to the position information is out of a range displayed in the display screen, a node including the content data located out of the range is selected from among the extraction result, andan object corresponding to the selected node is displayed as an object of the content data located out of the range.

Abstract
There is provided an information processing apparatus including a tree structure generation unit that generates a tree structure in which a leaf node represents content data associated with position information, serving as metadata, representing a location of a feature space defined based on a predetermined feature quantity, and a set of nodes whose distance in the feature space satisfies a predetermined condition is defined as a parent node of the nodes satisfying the predetermined condition, and a node extraction unit that, when any position information is specified, identifies a node in the tree structure to which the specified position information belongs, and extracts, according to a position of the identified node in the tree structure, one or a plurality of nodes, other than the node to which the specified position information belongs, from among the nodes in the tree structure.
