Short Bio
Hui Liu is a post-doctoral researcher at the Cognitive Systems Lab (CSL), University of Bremen, focusing on biomedical engineering, biosignal processing, human activity recognition (HAR), rehabilitation assistance, machine learning (ML), robotics, virtual reality, and music information retrieval (MIR). Hui Liu developed the first mobile system that senses and recognizes its users' movements in real-time, utilizing proximity wearable sensors integrated into a knee bandage. He invented Motion Units, a human activity modeling method with interpretability, generalizability, and expandability, rationalizing knowledge from kinesiology and automatic speech recognition into HAR research (2021). In 2022, Hui Liu proposed novel variants of the pitch histogram, the merged pitch histogram and the pitch-duration histogram, and successfully applied them to ethnomusicology studies and singing aids. Currently, Hui Liu has two technology patents pending. ... More >>
