1. A guidance support device to be used by being inserted into footwear, the guidance support device comprising:
a plurality of vibration generating members for generating vibrations at a plurality of positions on an epidermis of a foot of a user who uses the guidance support device;
a position acquisition part that acquires a current position;
a route acquisition part that acquires a route from the current position to a destination; and
a vibration control part that, on condition that a route pattern at a current position on the route fits any one of a plurality of predetermined route patterns, vibrates the vibration generating members in a combination corresponding to the route pattern at the current position, each of the route patterns showing a type of change in motion that should be taken by the user in order to guide the user to the destination, wherein
the guidance support device is a first guidance support device used by being worn on one of the feet of the user, and
the guidance support device further comprises:
a sensor information acquisition part that acquires first sensor information, which is information acquired by a sensor of a measurement part included in the first guidance support device, and second sensor information, which is information acquired by a sensor of a measurement part included in a second guidance support device used by being worn on an other foot of the user;
a failure detection part that analyzes a difference between the first sensor information and the second sensor information and detects a failure of at least one of the measurement part included in the first guidance support device or the measurement part included in the second guidance support device; and
