Opis

Digital information awareness is the process by whichpeople obtain knowledge about important personalinformation stored on their computers. This isusually provided graphically: when information ishidden from view it must be summoned to the front andusers are interrupted by the system, disregarding thecosts of the interruption. A solution is to usespeech output to complement the graphics, but its useinvokes anthropomorphic feelings whose cues must becarefully controlled if the system is to be regardedas humanized. This book describes the design of aspeech-based assistant nased on a set of intelligentagents and demonstrates how the content contextuallycues the significance of visually hidden information,and how the delivery impacts on the socialacceptability of a speaking system, includingattentive interruptions, linguistic variation andpoliteness. An empirical study showed that peoplefelt a degree of rapport with the such a system.These results led to the abstraction of designguidelines for speech-based systems that purport tobe humanized in nature. The book is useful toscholars and professionals concerned with the designof next-generation user interfaces.
