## Table of Contents

- Preface
  Summary: The CHIIoT workshop series brings together researchers and practitioners from human-computer interaction (HCI) design, computer science, and electrical engineering who are working on new challenges in industry and academia. The workshop provides a platform for participants to review and discuss challenges and opportunities in the intersection of computer-human interaction and the Internet of Things, focusing on human-centered applications using emerging connectivity and sensing technologies. We aim to jointly develop a design space and identify opportunities for future research--a community in which CHI and IoT researchers can exchange views and begin fruitful collaborations. There were 20 papers submitted for peer-review to both workshops. Out of these, 12 were finally accepted for this volume.
