1. An information display device, comprising:
a display;
a line-of-sight detection sensor configured to detect a line of sight of a user;
a line-of-sight position detector configured to detect, as a line-of-sight position, an intersection between the line of sight detected by the line-of-sight detection sensor and the display; and
display control circuitry configured to control the display in accordance with the line-of-sight position detected by the line-of-sight position detector, and
wherein the display control circuitry is further configured to, when detecting an entering behavior in which the line-of-sight position moves from an outside of a first area, which is a display area within the display, to an inside of the first area, display a predetermined menu in the first area,
wherein the first area is included in a line-of-sight detection area in which the line of sight can be detected by the line-of-sight detection sensor,
wherein the first area is narrower than the line-of-sight detection area, and
wherein the display control circuitry is further configured to, in a case of detecting a staying behavior in which the line-of-sight position continues to stay outside the first area for a predetermined period of time prior to the entering behavior, display the predetermined menu in the first area.
