Recently, UbiComp 2025 (ACM International Joint Conference on Pervasive and Ubiquitous Computing) was held in Espoo, Finland. In the Student Challenge, the team from the Institute for Network Sciences and Cyberspaces at Tsinghua University won the top prize, the "Best Student Challenge Award".

The winning team was advised by Associate Professor Yi Xin from the Institute for Network Sciences and Cyberspaces at Tsinghua University. The team leader was Zhang Shuning, a Ph.D. student at the Institute. Team members also include Ma Ying (Ph.D. student, University of Melbourne), Zang Qucheng (Master student, China Academy of Art), and Hu Yongquan (Ph.D. student, University of New South Wales). Their project, "SituGuard: LLM-based Fine-grained Smart Glass Privacy Control in Home Environments," addressed personal privacy challenges in smart home environments. Utilizing Large Language Models and innovative human-computer interaction methods, they proposed an automated, intelligent privacy control solution and validated its effectiveness in smart home settings.

UbiComp is a flagship international conference in the field of pervasive and ubiquitous computing, and is recommended as a Rank-A international conference by the China Computer Federation (CCF). As an official competition of the conference, the Student Challenge attracted nearly 100 participants from 27 student teams around the world. After a rigorous selection process by the organizing committee, 12 teams were selected for the on-site presentation round to compete for the final awards. The "Best Student Challenge Award" is the sole highest honor in this track, awarded to the individual or team demonstrating excellence across all criteria, including innovation, judge evaluations, and audience feedback.
