A Study on the Sound Therapy Interaction Design to Alleviate Homesickness: The HomeSeek App among Chinese Users

Research in the field of psychological health care has confirmed that chronic homesickness can exacerbate emotional problems. However, there is a lack of diverse products in the design field that can effectively address the issue of alleviating homesickness. This study explores how interaction design can mitigate homesickness-related anxiety while delivering a good user experience, from an application-driven perspective. An inclusive design approach was adopted. Firstly, an online survey was conducted in China through social media platforms (WeChat and websites), and 323 responses were analyzed to examine Chinese preferences for sounds that alleviate homesickness and the influence of various characteristics on the perception of hometown sounds. Secondly, personas were created to capture user needs. Based on regional differences, local sound characteristics, and adaptation to various audience backgrounds, this study examined the effects of these sounds on alleviating homesickness across different scenarios and proposed a sound therapy design model. The practical application of this model was demonstrated through the HomeSeek app, which provides personalized therapeutic experiences. Finally, an application usability test was conducted. The findings indicated that 92.5% of participants were satisfied with the homesickness therapy experience, demonstrating its effectiveness in alleviating homesickness and providing strong support for the research model.
