The story
The term cognetics was coined and trademarked by Charles Kreitzberg in 1982 when he started Cognetics Corporation, one of the first user experience design companies. The term cognetics was used independently by Jef Raskin and Charles Kreitzberg. Raskin used the term cognetics in his book The Humane Interface (Addison-Wesley, 2000) to mean "the ergonomics of the mind." According to Raskin, "Cognetics brings interface design out of the mystic realm of guruism, transforming it into an engineering discipline with a rigorous theoretical framework".
