Natural User Interfaces

Abstract

In this chapter, we describe what has come to be termed “natural user interfaces” (NUIs) and review how they have been used with individuals on the autism spectrum. Although the word natural can be hotly contested given that most movements are not actually “natural” but learned, we use the standard phrasing of natural user interfaces in this scope of the review. By this definition, “natural” input encompasses a large variety of input techniques beyond the traditional desktop computer, such as the use of pen, gestures, speech, tangible computing, and eye-tracking technologies. Here, we define NUIs as involving the use of input devices and techniques beyond traditional mice and keyboards. Specific input techniques include penwriting, gestures, speech/voice, eyetracking, tangible computing, and smart objects. Natural user interfaces also involve interaction with a system rather than just providing passive input.
