During May 6~8, the 9th workshop was held in Xi’an, China. 65 members from China, Japan, and Korea participated in this workshop, which featured 5 keynote speeches and 16 presentation sessions. The latest research topics on IoT, wireless sensing, mobile and ubiquitous computing, AI-driven data analytics, and integrated healthcare ecosystems were discussed. Presenters were able to gain new insights through discussions with audience members. The wide range of topics covered in the workshop provided participants with a valuable opportunity to broaden their research perspectives by gaining fresh perspectives from fields with which they are rarely involved. We would like to express our heartfelt gratitude for your invaluable presentation and attendance. In addition to the academic content, we learned a lot about the history and culture of Xi’an. The next workshop will be held in Korea. We are looking forward to seeing you there.
