The term interaction design was coined by Bill Moggridge[2] and Bill Verplank in the mid-1980s, but it took 10 years before the concept started to take hold.[2]:xviii To Verplank, it was an adaptation of the computer science term user interface design for the industrial design profession.[3] 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.[4]
