Research On The User Experience Design Of Voice User Interface In Smart Products For Senior Users

With the development of the fields such as economy,healthcare,science,and the elderly industry,the elderly have more and more opportunities to use smart products.However,there are few smart products that can fully consider the physiological and psychological characteristics of elderly users to customize for elderly users.At present,research in this area is still in its infancy.As a new interaction method,voice interaction can bring a brand-new experience of smart products to elderly users,and has a large research space and research value.Therefore,this article based on the features and advantages of the voice interaction mode started with the physiological,cognitive,and response characteristics of elderly users,and explored how to apply voice interaction in smart products to bring better user experience to elderly users.Firstly,the article studied the physiological,cognitive and response characteristics of the elderly through the literature survey.Studied the usual smart product usage of the elderly users by using user research methods such as questionnaire surveys,user interviews,and operation observations,and derived basic characteristics of elderly users.Analyzed the needs of elderly users.Secondly,the article studied the formation process,advantages,disadvantages,and limitations of voice interaction in elderly interaction through the literature survey and network survey.It analyzed the support and limitation of technology for voice interaction.Studied the scope and application case of voice interaction to analyze the experiences that current intelligent voice can bring to elderly users and future trends of voice interaction of elderly smart products.Then,the article designed four different experiments,including Interaction Channel A/B Test,Information Account Test,Earcon Understanding Test,and Voice Preference Test,according to the results before.Finally,Derived the principles of the voice interaction experience design for elderly users at the structural layer,the skeleton layer and the surface layer by integrating the results of previous theoretical research,user research and influencing factor analysis.Applied the design principles to practice,explored a more natural and suitable interaction method of smart products for elderly users.
