HAPRec: Hybrid Activity and Plan Recognizer
This work addresses the need for computer-based assistants to understand human activities and goals in assisted living settings, but it appears incremental as it combines existing modules without claiming major breakthroughs.
The paper tackles the problem of recognizing high-level activities and goals in indoor environments for ambient assisted living, proposing a hybrid approach that combines action recognition with goal recognition to identify the subject's ultimate goal.
Computer-based assistants have recently attracted much interest due to its applicability to ambient assisted living. Such assistants have to detect and recognize the high-level activities and goals performed by the assisted human beings. In this work, we demonstrate activity recognition in an indoor environment in order to identify the goal towards which the subject of the video is pursuing. Our hybrid approach combines an action recognition module and a goal recognition algorithm to identify the ultimate goal of the subject in the video.
