LastAct: Trajectory-Guided Latest-Activity Localization for Real-Time Smart-Home Activity Recognition
arXiv:2606.00260v1 Announce Type: cross Abstract: Human Activity Recognition (HAR) from ambient sensors enables smart-home applications such as health monitoring and assisted living. In realistic deployments, however, sensor events arrive as a continuous stream and activity boundaries are unknown. Sliding-window inference therefore produces many windows that straddle transitions and contain mixed activities, creating boundary contamination that violates the pre-segmented instance assumption used by most benchmarks and models. Moreover, many pipelines under-use spatial context by treating senso
The continuous stream of sensor data in smart homes presents ongoing challenges for accurate real-time activity recognition, a problem highlighted by the described 'boundary contamination'. This paper addresses a key issue in deploying practical AI for assisted living and health monitoring.
This development improves real-time human activity recognition in smart homes, critical for reliable health monitoring and assisted living applications. It marks progress in making AI systems more robust and practical for continuous, real-world data streams.
Real-time human activity recognition systems will become more accurate and robust against mixed-activity data, reducing errors in smart-home applications. This enhances the reliability of AI for monitoring elderly or infirm individuals.
