Abstract: In a guidance support device to be used by being inserted into footwear, a plurality of vibration generating members generate vibrations at a plurality of positions on a foot of a user who uses the guidance support device. A position acquisition part acquires a current position. A route acquisition part acquires a route from the current position to a destination. A vibration control part, on condition that a route pattern at a current position on the route fits any one of a plurality of predetermined patterns, vibrates the vibration generating members in a combination corresponding to the pattern.

Abstract: A display control device includes: an illuminance acquisition unit configured to acquire surrounding illuminance of a display unit on the basis of one or both of first illuminance detected by a first illuminance sensor and second illuminance detected by a second illuminance sensor; a storage unit configured to store correspondence information in which illuminance is associated with target luminance; a luminance control unit configured to control luminance of a screen of the display unit on the basis of the acquired illuminance and the correspondence information; and an abnormality detection unit configured to detect an abnormality of at least the first illuminance sensor. The luminance control unit acquires the target luminance associated with the surrounding illuminance of the display unit from the correspondence information on the basis of the surrounding illuminance when the abnormality of the first illuminance sensor is not detected.

Abstract: A display control device includes an illuminance acquisition unit configured to acquire ambient illuminance, and a luminance control unit configured to control luminance of an image to be displayed on a display unit on the basis of the illuminance acquired by the illuminance acquisition unit. When the illuminance acquired by the illuminance acquisition unit satisfies a predetermined condition during execution of luminance control in a first mode in which the luminance is changed at a first luminance change speed, the luminance control unit shifts to a second mode in which the luminance is changed at a second luminance change speed faster than the first luminance change speed, and returns to the first mode when a predetermined time has elapsed after shifting to the second mode.
