1. An information display system, comprising circuitry configured to:
acquire detection information including information on a posture of a user and information on a line of sight of the user;
project an image onto a projection destination located in a projection direction with respect to the user;
cause the image to be projected onto the projection destination based on the detection information and information on the projection direction;
change a projection method for the image to be projected onto the projection destination, based on a difference between a direction of the line of sight and the projection direction, the direction of the line of sight being obtained from the detection information; and
in a case where the difference between the direction of the line of sight and the projection direction is greater than a predetermined threshold, project another image onto another projection destination based on another difference between the direction of the line of sight and another projection direction, the another difference being less than the predetermined threshold.
