LLM-based HAR frameworks will achieve widespread on-device deployment within 18 months.
The STELLA framework demonstrates that LLMs can be effectively utilized for on-device human activity recognition with real-time inference capabilities. As LLM efficiency improves and hardware capabilities increase, it's plausible that such frameworks will transition from research to practical, widespread deployment on consumer devices for personalized HAR applications.
Novel frameworks are actively addressing domain shift and data efficiency challenges in HAR.
Recent research on IBIS for Wi-Fi sensing and a new framework for inertial sensors indicates a strong industry focus on overcoming key limitations in HAR. These efforts aim to improve robustness against environmental changes and reduce the substantial data requirements for deep learning models, suggesting a trend towards more practical and efficient HAR solutions.
Federated learning approaches will become standard for privacy-preserving HAR on edge devices.
The exploration of FedAvg for HAR highlights the potential of federated learning to balance personalization and generalization while maintaining data privacy. As concerns over data privacy grow, federated learning offers a compelling solution for training HAR models on distributed edge devices without centralizing sensitive user data.
