Abstract: A skill acquisition assistance method includes a first stimulus generating step of acquiring first and second tactile data indicating tactile senses corresponding to a first body part based on an action of the first body part during work time when first and second workers perform the same work and generating a first stimulus based on the first tactile data by a stimulus transmission section mounted on a second body part different from the first body part of the first worker and a second stimulus generating step of switching a stimulus generated by the stimulus transmission section to a second stimulus based on the second tactile data in conjunction with the action of the first body part of the first worker.

Abstract: A psychosomatic state adjustment support device includes: a storage section that stores a target psychosomatic state for each destination of a moving body; a specification section that specifies a current psychosomatic state of an occupant of the moving body; an acquisition section that acquires a destination of the moving body; a deciding section that decides a vibration pattern based on the target psychosomatic state according to the destination and the current psychosomatic state; and a control section that applies a vibration stimulation to the occupant by causing a vibration applying section provided in a seat on which the occupant is seated to vibrate based on the vibration pattern.

Abstract: The movement inducing device includes a plurality of air bags, each being provided with a contacting portion configured to contact with a user and induce a movement of an intended skeletal muscle of the user; a drive mechanism configured to expand and compress the air bags by adjusting supply and discharge of air to and from each air bag and a control unit provided with a drive control unit configured to control driving of the drive mechanism to make the intended skeletal muscle of the user perform at least one of an isotonic muscle activity, an isometric muscle activity and an isokinetic muscle activity.
