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

1. 1Collect and preprocess IMU data from head-mounted sensors
2. 2Define behavioral activity categories that balance application needs with sensor observability
3. 3Construct and annotate a large dataset, such as Ego4D, for training and evaluation
4. 4Train machine learning models to recognize behavioral activities from IMU data
5. 5Evaluate and fine-tune the models for improved accuracy and robustness

Machine learning engineers and data scientists on AR development teams can benefit from this knowledge to improve the contextual awareness of smart glasses

💡 Head-mounted IMU data can be used to recognize high-level behavioral activities, going beyond basic motion primitives
