A method of displaying information on a display of a display device via a display controller includes imaging a user of the display device using an imaging device integrated with the display device or provided around the display device, detecting a line of sight of the user from an image captured by the imaging device, determining whether the display exists within a central visual field region centered on the detected line of sight of the user or within a peripheral visual field region located outside the central visual field region, displaying notification information on the display in a first display form when the display exists within the central visual field region, and displaying the notification information on the display in a second display form when the display exists within the peripheral visual field region, the second display form having a higher abstraction level than that in the first display form.
