The Hug Machine was invented by Temple Grandin as a way to treat her autism. From Wikipedia
The idea for the hug machine was devised during a visit to her aunt's Colorado ranch, where she noted the way cattle were vaccinated while confined in a squeeze chute, and how some of the cattle immediately calmed down after pressure was administered. She realized the deep pressure from the chute had a calming effect, and decided that might well settle down her own hypersensitivity. Whereas psychologists at her high school sought to confiscate her prototype hug machine, her science teacher encouraged her to determine just why it helped resolve her anxiety and sensory issues.
