Human Activity Recognition has been researched in thousands of papers so far, with mobile / environmental sensors in ubiquitous / pervasive domains, and with cameras in vision domains. As well, Human Behavior Analysis is also explored for long-term health care, rehabilitation, emotion recognition, human interaction, and so on. However, many research challenges remain for realistic settings, such as complex and ambiguous activities / behavior, optimal sensor combinations, (deep) machine learning, data collection, platform systems, and killer applications.

In this conference, we comprehend such research domains as ABC: Activity and Behavior Computing, and provide an open and a confluent place for discussing various aspects and the future of the ABC.

CALL FOR PAPERS

We welcome 3 categories of papers: regular papers, position papers, and challenge papers. The submitted papers are peer reviewed by expert researchers, and accepted based on the research quality.

Accepted and presented papers will be published as IEEE Proceedings or a J-Stage open access journal.
