Proceedings of the 2020 CHI Conference on Human Factors in Computing Systems

Aloha! We are excited to welcome you to CHI 2020 in beautiful Honolulu, Hawai'i! Although CHI has strong origins in the USA, it has never been to Hawai'i. We see this rather "unusual" location for a conference as both an acknowledgement of the role underrepresented regions play in the field of Human-Computer Interaction as well as a symbol for more outreach to the rest of the world. The ACM CHI Conference on Human Factors in Computing Systems is the premier international conference of Human-Computer Interaction. CHI - pronounced "kai" - is a place where researchers and practitioners gather from across the world to discuss the latest in interactive technology. We are a multicultural community from highly diverse backgrounds who together investigate new and creative ways for people to interact. CHI has a rich history of bringing together people from different disciplines, cultures, sectors, communities and backgrounds. Through CHI, designers, researchers and practitioners come together with the common purpose of creating technology that works for people and society. We are increasingly realizing how our technology use is changing how we delineate work and pleasure, how it is advancing our productivity but at the same time threatening our wellbeing. In choosing a beautiful location like Hawai'i, we hope we highlight the importance of work-life balance and also elicit new discussions on such critical perspectives about the future of interactive technology. Thanks to our massive numbers of volunteers and help from ACM and its SIGCHI members, we are excited to present a vibrant technical and social programme for you to experience. Over six days, participants can join and continue to engage with the CHI community and explore technology and world-class research, and engage in discussions with designers, researchers, students, and practitioners! Ho'omalu-o means "to conserve; to use or manage wisely" in the Hawaiian language. One of our goals for CHI 2020 is to make more sustainable choices wherever we can, recognising, of course, that any travel, especially to locations like ours, has a significant impact on the environment. Working with the Sustainability Chairs, we have chosen recycled, biodegradable or eco-friendly products and engaged with local suppliers, wherever possible. We have implemented options to reduce travel related to the conference organisation by using videoconference meetings as much as possible. We have worked with the CHI Steering and Executive Committee to identify future opportunities to reduce travel and to reduce the number of meetings. We have removed the conference bag and gifts by default and encouraged the selection of more sustainable food choices (including the decision not to serve red meat). We have also chosen reusable or compostable crockery and cutlery where possible and are donating any remaining food to a homeless shelter to avoid food waste. Furthermore, we have chosen to locate all activities in or near the Convention Centre and negotiated deals with hotels nearby to reduce the need for transportation. The Convention Centre itself is the first and only public assembly convention centre to earn LEED v.4 O+M Gold Certification in the United States. In the spirit of Ho'omaluo- , we have also decided to set the default temperature in the venue higher to reduce air condition energy usage. A particular highlight is the Interactivity programme, which will be launched at the Reception on Monday evening, giving a live glimpse into the future with hands-on prototypes, design experiences as well as inspirational technologies. We are also excited to continue the commitment to making CHI, and CHI content, more widely accessible. We will be live-streaming even more paper sessions. We also provide a nursing room, all-gender bathrooms, badge pronouns, a desensitization room and a prayer room.
