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.

This book constitutes 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 55 papers presented in this volume are organized in topical sections as follows: interaction design; cognitive issues in HCI; accessibility and universal access; learning and games; HCI in health and rehabilitation; HCI in business and society; big data, machine learning and visual analytics; and user studies.

This book constitutes late breaking papers from the 22nd International Conference on Human-Computer Interaction, HCII 2020, which was held in July 2020.
