The three-volume set CCIS 1032, CCIS 1033, and CCIS 1034 contains the extended abstracts of the posters presented during the 21st International Conference on Human-Computer Interaction, HCII 2019, which took place in Orlando, Florida, in July 2019.The total of 1274 papers and 209 posters included in the 35 HCII 2019 proceedings volumes was carefully reviewed and selected from 5029 submissions. The 208 papers presented in these three volumes are organized in topical sections as follows: Part I: design, development and evaluation methods and technique; multimodal Interaction; security and trust; accessibility and universal access; design and user experience case studies. Part II:interacting with games; human robot interaction; AI and machine learning in HCI; physiological measuring; object, motion and activity recognition; virtual and augmented reality; intelligent interactive environments. Part III: new trends in social media; HCI in business; learning technologies; HCI in transport and autonomous driving; HCI for health and well-being.

This set of 35 volumes constitutes the proceedings of all of the conferences affiliated with HCI International 2019, which was held in Orlando, Florida, USA, in July 2019. The 1274 papers and 209 posters presented were carefully reviewed and selected from 5029 submissions. The respective focus of the 18 conference is as follows: Human-Computer Interaction; Human Interface and the Management of Information; Engineering Psychology and Cognitive Ergonomics; Universal Access in Human-Computer Interation; Virtual, Augmented and Mixed Reality; Cross-Cultural Design; Social Computing and Social Media; Augmented Cognition; Digital Human Modeling and Applications in Health, Safety, Ergonomics and Risk Management; Design, User Experience, and Usability; Distributed, Ambient and Pervasive Interactions; HCI in Business, Government and Organizations; Learning and Collaboration Technologies; Human Aspects of IT for the Aged Population; HCI for Cybersecurity, Privacy and Trust; HCI in Games, HCI in Mobility, Transport and Automotive Systems; and Adaptive Instructional Systems. The set therefore provides readers with a comprehensive overview of ongoing research and development within the broad field of Human-Computer Interaction.

This year the 21st International Conference on Human-Computer Interaction, HCII 2019, which was held in Orlando, Florida, USA, in July 2019, introduced the additional option of "late-breaking work", which applied both for papers and posters with the corresponding volumes of the proceedings. The 47 late-breaking papers included in this volume were published after the conference has taken place. They were organized in the following topical sections: user experience design and evaluation; information, visualization, and decision making; virtual and augmented reality; learning and games; human and task models in HCI; and design and user experience case studies.
