Title: The Data Dilemma in Designing Low-Cost, High-Precision Wearables for Users’ Wellness Tracking

Abstract: When designing wearables for individuals’ everyday wellness tracking, balancing device affordability with the need for accurate and privacy-preserving interpretation of sensor data is key. I will address in this talk recent works that directly address this by exploring strategies that span sensor design, data annotation, multimodal fusion, and privacy-aware processing. Own work on wearable sensing such as DeepPPG, WESAD, or WEAR illustrate the impact that sensor-specific methods can have, while studies in (federated) fitness tracking, hand washing, or epilepsy seizure detection show the challenges and promises in actual deployments. I’ll finally show some hands-on examples of embedded wearable platforms and the importance of open-source, reproducible tools.

Bio: Kristof is a professor for Ubiquitous Computing at the University of Siegen (in Germany) and interested for a long time in wearable and embedded sensing systems research, as well as activity and affect recognition. After his studies in Brussels, Belgium, he obtained his PhD with Hans Gellersen at Lancaster University (UK) and after a PostDoc with Bernt Schiele at the Technical University of Darmstadt (Germany), obtained an Emmy Noether Research grant, after which he became a professor for embedded systems at the University of Freiburg (Germany). He was recently co-chair of UbiComp/ISWC 2023, has in the past chaired the ISWC Steering Committee, and currently is an Editor for the ACM IMWUT journal.

Title: User Experience Measurement and Innovation in Consumer Products

Abstract: User experience is a key success factor for consumer products. However, there has been lacking a mathematical computation model for user experience measurement. The research on the impacting factors of user experience and the construction of a measurement model are highly desired by the consumer devices and internet services Industry. Meanwhile, creativity and innovation are regarded extremely critical in achieving great user experience. This keynote will discuss how to measure the user experience of a product and the best practices leading to customer satisfaction.

Bio: Haining Zhang is the Dean and Chair Professor of Software College at Nankai University as well as the Director of Tianjin Key Lab of Software Experience and Human-Computer Interaction. His main research interests include software user experience, AI applications and Human Computer Interaction. Prior to his teaching career, Haining spent 27 years in Internet and smartphone industry with 14 years at Apple in US serving as software development director and the head of R&D for greater China. He has been granted more than 40 US invention patents and involved in multiple iPhone and iOS development projects.
