Long-Term User Experience of Older Adults Living Alone on Home-Based Intelligent Care System: A Retrospective Interview Study

Knowledge on the long-term User Experience (UX) of older adults in using Home-based Intelligent Care System (HICS) is limited, even though it is imperative for older adults’ continuous use of HICS to promote their quality of life. This study aims to investigate the long-term User Experience (UX) of older adults in using Home-based Intelligent Care System (HICS), and to understand how its elements change over time and which system attributes cause these changes. Based on the Change-oriented Analysis of the Relationship between Product and User (CORPUS), the 23 older adults living alone who used the same HICS for half a year or more were interviewed through Focus Group. Conventional qualitative Content Analysis was adopted to analyze the interview data. A two-stage model of the older adults’ long-term UX was established. In Orientation stage, UX elements mainly included Usability Experience, Affect Experience, and Social Value Experience. In the Incorporation stage, there were only Usability Experience and Social Value Experience. The system attributes causing these UX elements were discussed. This study is a supplement to researches in the field of home-based senior care that only discussed the effect of HICS from static perspective, and also riches the researches of the Human-Computer Interaction field that mostly focused on the young users.
