This book presents the best-selected research papers presented at the 3rd International Conference on Activity and Behavior Computing (ABC 2021), during 20-22 October 2021. The book includes works related to the field of vision- and sensor-based human action or activity and behavior analysis and recognition. It covers human activity recognition (HAR), action understanding, gait analysis, gesture recognition, behavior analysis, emotion, and affective computing, and related areas. The book addresses various challenges and aspects of human activity recognition-both in sensor-based and vision-based domains. It can be considered as an excellent treasury related to the human activity and behavior computing.

Sozo Inoue, Ph.D., is Professor in Kyushu Institute of Technology, Japan. His research interests include human activity recognition with smart phones, and healthcare application of Web/pervasive/ubiquitous systems. Currently he is working on verification studies in real field applications, and collecting and providing a large-scale open dataset for activity recognition, such as a mobile accelerator dataset with about 35,000 activity data from more than 200 subjects, nurses' sensor data combined with 100 patients' sensor data and medical records, and 34 households' light sensor data set for 4 months combined with smart meter data. Inoue has a Ph.D. of Engineering from Kyushu University in 2003. After completion of his degree, he was appointed as Assistant Professor in the Faculty of Information Science and Electrical Engineering at the Kyushu University, Japan. He then moved to the Research Department at the Kyushu University Library in 2006. Since 2009, he is appointed as Associate Professor in the Faculty of Engineering at Kyushu Institute of Technology, Japan, and moved to Graduate School of Life Science and Systems Engineering at Kyushu Institute of Technology in 2018. Meanwhile, he was Guest Professor in Kyushu University, Visiting Professor at Karlsruhe Institute of Technology, Germany, in 2014, Special Researcher at Institute of Systems, Information Technologies and Nanotechnologies (ISIT) during 2015-2016, and Guest Professor at University of Los Andes in Colombia in 2019. He is Technical Advisor of Team AIBOD Co. Ltd since 2017, and Guest Researcher at RIKEN Center for Advanced Intelligence Project (AIP) since 2017. He is Member of the IEEE Computer Society, the ACM, the Information Processing Society of Japan (IPSJ), the Institute of Electronics, Information and Communication Engineers (IEICE), the Japan Society for Fuzzy Theory and Intelligent Informatics, the Japan Association for Medical Informatics (JAMI), and the Database Society of Japan (DBSJ).
Daniel Roggen, Ph.D., received the master's and Ph.D. degrees from the École Polytechnique Fédérale de Lausanne, Switzerland, in 2001 and 2005, respectively.
