Information retrieval apparatus
First Claim
1. An information retrieval apparatus, comprising:
- a three-dimensional display unit for displaying a set of indexes controlling attributes of a database in a three-dimensional image space in the sight of a user with index display images so as to allow the user to visually recognize said set of indexes;
an input unit for detecting a motion pattern of the user'"'"'s body against said index display images as input information and for displaying the motion patterns in said three-dimensional image space; and
an arithmetic operation unit for recognizing the input information of the motion patterns received through said input unit, for selecting indexes displayed with the corresponding index display images in accordance with the motion patterns and for performing set logical operations of the selected indexes in accordance with the motion patterns so as to collate and retrieve information from said database,wherein the index display images can be moved in the three-dimensional image space in accordance with the motion patterns of the user'"'"'s body, and the index information of the indexes vary in accordance with the positions of the index display images in the three-dimensional image space.

Abstract
An information retrieval apparatus features a three-dimensional display unit for displaying a set of indexes controlling attributes of a database in a three-dimensional image space in sight of a user with index display images so as to allow the user to visually recognize the set of indexes. An input unit detects motion patterns of the user'"'"'s body against the index display images as input information and displays the motion patterns in the three-dimensional image space. An arithmetic operation unit recognizes the input information of the motion patterns received through the input unit and performs set logical operations of selected images in accordance with the motion patterns so as to collate and retrieve information from the database. The user can further directly operate index display images in a three-dimensional image space or a two-dimensional image space without the necessity of a keyboard and recognize input information with his body'"'"'s motion patterns. The arithmetic operation unit performs set logical operations of indexes displayed with predetermined index display images so as to retrieve desired information from a database. Thus, even if the user does not have enough experience in operating conventional input and output units, such as a keyboard, he can readily and accurately retrieve desired objects from a medium such as a database.

9. A information retrieval apparatus, comprising:
-
a three-dimensional display unit for displaying a set of indexes controlling attributes of a database in a three-dimensional image space in the sight of a user with index capsule images and a set of logical operation means with operation capsule images so as to allow the user to visually recognize said set of indexes and said set of logical operation means; an input unit for detecting motion patterns of the user'"'"'s body against said index capsule images and said operation capsule images as input information and for displaying the motion patterns in said three-dimensional image space; and an arithmetic operation unit for recognizing the input information of the motion patterns received through said input unit, for selecting indexes displayed with the corresponding index capsule images and logical operation means displayed with the corresponding operation capsule images in accordance with the motion patterns and for performing set logical operations of the selected indexes by using the selected logical operation means so as to collate and retrieve information from said database, wherein the index capsule images can be moved in the three-dimensional image space in accordance with the motion patterns of the user'"'"'s body, and the index information of the indexes vary in accordance with the positions of the index display images in the three-dimensional image space.
