Abstract
Since voice-based user interfaces (VUIs) have now been adopted by smart phones and smart speakers, the number of opportunities for consumers to use these has increased. There are a wide range of situations in which VUI devices are used, such as in the home, office, car, and in public spaces; however, the target users of VUIs at the research stage were limited to seniors and disabled people, who found it difficult to use touch panels or keyboards. This paper focuses on VUI devices for consumers, and examines the usage patterns of VUI devices in everyday life. UX design strategies are proposed for VUI devices based on these data. Firstly, a questionnaire is conducted in order to collect user data, and 10 interviewees are then identified by focusing on the users who use VUI devices more than once per day. About five hours of interview data are used as a corpus, and this is analyzed using a qualitative approach. Finally, seven key findings are presented that can contribute to the development of further UX design strategies for VUI devices in consumers' daily life.
