aUI is a constructed language created by W. John Weilgart (1913–1981), a philologist and psychoanalyst originally from Vienna, Austria. He described it as "the language of space" and published a general work in 1975 and later textbook.

Weilgart's motivation for inventing the language was to create a form of communication based on what he proposed to be universal, basic elements of human thought and expression, and incorporated it into his psychotherapy work.
