The term interaction design was coined by Bill Moggridge and Bill Verplank in the mid-1980s, but it took 10 years before the concept started to take hold. To Verplank, it was an adaptation of the computer science term user interface design for the industrial design profession. To Moggridge, it was an improvement over soft-face, which he had coined in 1984 to refer to the application of industrial design to products containing software.*
