Beyond Motion Primitives: Behavioral Activity Recognition from Head-Mounted IMU

Researchers from Harvard's AI and Robotics Lab have developed HiT-HAR, a hierarchical deep learning model that enables AR smart glasses to recognize complex human behaviors beyond basic motion primitives using only head-mounted IMU sensors. The team created a 160K-sample dataset and demonstrated that architectural choices exploiting temporal context outperform simple model scaling, advancing the feasibility of always-on behavioral context awareness for augmented reality applications.

KAN-MLP-Mixer: A comprehensive investigation of the usage of Kolmogorov-Arnold Networks (KANs) for improving IMU-based Human Activity Recognition

Researchers propose KAN-MLP-Mixer, a hybrid neural network architecture that combines Kolmogorov-Arnold Networks (KANs) with traditional MLPs for human activity recognition from IMU sensors. The model achieves 5.33% improvement over pure-MLP baselines by leveraging KANs' precision in input embedding and classification while retaining MLPs' noise robustness for intermediate processing.
