The INTERACT Conferences are an important platform for researchers and practitioners in the field of human-computer interaction (HCI) to showcase their work. They are organised biennially by the International Federation for Information Processing Technical Committee on Human–Computer Interaction (IFIP TC13), a committee of 30 member national societies and 9 Working Groups. The 17th IFIP TC13 International Conference on Human-Computer Interaction (INTERACT 2019) took place during 2-6 September 2019 in Paphos, Cyprus. The conference was held at the Coral Beach Hotel Resort, and was co-sponsored by the Cyprus University of Technology and Tallinn University, in cooperation with ACM and ACM SIGCHI. With an emphasis on inclusiveness, these conferences work to lower the barriers that prevent people in developing countries from participating in conferences. As a multidisciplinary field, HCI requires interaction and discussion among diverse people with different interests and backgrounds. This volume contains the Adjunct Proceedings to the 17th INTERACT Conference, and comprises a series of papers from the workshops. It follows the INTERACT Conference tradition of the publication of adjunct proceedings by a University Press which has a connection to the conference itself. This tradition has been established to enhance the outreach and reputation of the University Press chosen. For INTERACT 2019, both the Conference Program Chair, Dr Fernando Loizides, and the Adjunct Proceedings Chair of the conference, Dr Usashi Chatterjee, work at Cardiff University which is the home of Cardiff University Press.
