Information presentation device and information presentation method
First Claim
1. An information presentation device which presents information on a see-through presentation screen to a user, the information presentation device comprising:
- a status information obtaining unit operable to obtain status information regarding a status of the user;
an observed line of sight predicting unit operable to predict, on a predetermined time basis, a future sight point of an observed line of sight from eyes of a user to an observation target in the outside world through the presentation screen, based on the status information obtained by the status information obtaining unit;
a presented information obtaining unit operable to obtain information to be presented to the user as presented information, the presented information including one of text, video, image and signal information;
a recognized line of sight predicting unit operable to predict, on the predetermined time basis, a future sight point of a recognized line of sight from the eyes of the user to a point on the presentation screen on which the information obtained by the presented information obtaining unit is presented, based on a predetermined rule depending on a type and an importance of the presented information;
a presentation method determining unit operable to obtain, on the predetermined time basis, an intersection point of the observed line of sight and a plane, and an intersection point of the recognized line of sight and the plane, and to determine a presentation method of the presented information so that a distance between the intersection points falls within a predetermined range; and
an information presenting unit operable to present the presented information in the presentation method, the presented information being obtained by the presented information obtaining unit and the presentation method being obtained by the presentation method determining unit.

Abstract
An information presentation device includes a status information obtaining unit which obtains status information regarding a status of the user; an observed line of sight predicting unit which predicts, based on the status information, an observed line of sight of the user who observes the outside world; and a presented information obtaining unit which obtains the information to be presented to the user. Additionally, a recognized line of sight predicting unit predicts a recognized line of sight of the user who recognizes the presented information; a presentation method determining unit determines a presentation method of the presented information based on the observed line of sight and the recognized line of sight; and an information presenting unit presents the presented information in the method determined in the presentation method determining unit.
