Abstract: The present application discloses an information observation method and an information observation apparatus, and relates to the field of multimedia information processing technologies. The method comprises: detecting a position of a sightline focusing point of an observer; in response to that it is detected that the sightline focusing point of the observer moves away from an observed object, judging whether the observer has observed all important information on the observed object; and in response to that it is judged that the observer has not observed all important information on the observed object, reminding the observer. For the method and the apparatus in embodiments of the present application, from the perspective of an actual observation behavior of an observer, a position of a sightline focusing point of the observer is detected to determine an observation behavior of the observer for important information, so as to radically prevent missing of important information.
