Abstract

The present invention provides an information presentation device which allows the user to recognize presented information while the safety of the user is further ensured.

The information presentation device includes: a status information obtaining unit 101 which obtains status information regarding a status of the user; an observed line of sight predicting unit 102 which predicts, based on the status information, an observed line of sight of the user who observes the outside world; a presented information obtaining unit 103 which obtains the information to be presented to the user; a recognized line of sight predicting unit 104 which predicts a recognized line of sight of the user who recognizes the presented information; a presentation method determining unit 105 which 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 106 which presents the presented information in the method determined in the presentation method determining unit 105.
