ABSTRACT:
In order to obtain an information retrieval apparatus for performing retrieval from an anchor to be set with respect to a virtual three dimensional space, and to enable retrieval over a wide retrieval range through an easy-to-use user interface, a movement anchor generator unit is provided to generate a movement anchor corresponding to a change in viewpoint information. A three dimensional space generator unit generates not only ordinary objects, but also objects representing movement anchors in three dimensional images. A user selects a virtual object, which is a movement anchor, on an image. Linked data regarding the movement anchor is registered in a linked data storage unit. A retrieval unit can perform retrieval, not only with ordinary objects as anchors, but also through the movement anchor. Any application program execution unit for processing the display of a retrieval result can be used, and a wide range of linked information can be handled.
