1. An awakening inducing device comprising:
one or more vibrators disposed in a seat at a position where the one or more vibrators oppose at least one of a muscle belly portion or an insertion portion of a hamstring of a user sitting on the seat;
a processor; and
a memory including a program that, when executed by the processor, causes the processor to perform operations, the operations including:
controlling the one or more vibrators such that the one or more vibrators give vibration stimulation to the at least one of the muscle belly portion or the insertion portion, wherein
the one or more vibrators includes an eccentric motor, a rotary motor with a cam mechanism, or a voice coil motor,
the one or more vibrators includes a housing that houses the eccentric motor, the rotary motor with the cam mechanism, or the voice coil motor, and
the housing includes a projection portion projecting from the housing, the housing being configured to vibrate such that the projection portion presses the user to give the vibration stimulation to the at least one of the muscle belly portion or the insertion portion, and
the one or more vibrators vibrate in any one of:
(i) a vibration pattern in which an amplitude of vibrations of each of the one or more vibrators is increased gradually,
(ii) a vibration pattern in which a cycle of vibrations of each of the one or more vibrators is increased gradually, or
(iii) a vibration pattern in which intervals of vibrations of each of the one or more vibrators are reduced gradually.
