In exactly three months, the thirteenth edition of the Animal-Computer Interaction International Conference (ACI 2026) will begin. The conference will take place from December 2 to 5, 2026, at the FHNW Campus Brugg-Windisch in Switzerland. For the first time in its history, the ACI conference will be held in continental Europe. Registration has been open since the end of July, and preparations for the conference are well underway. All submitted papers have now been peer-reviewed, and acceptance and rejection notifications have been sent to the authors. General Chair Oliver Bendel is pleased to see the conference program taking shape and looks forward to welcoming the ACI community to Brugg-Windisch in December. This year’s conference will also feature three workshops, providing opportunities for focused discussion, exchange, and collaboration on topics relevant to Animal-Computer Interaction and related fields. ACI 2026 brings together perspectives from computer science, informatics, engineering, interaction design, animal behavior and welfare science, veterinary science, ecology, sociology, philosophy, and related disciplines. The conference provides a forum for theoretical, methodological, empirical, and ethical work that advances dialogue around animal-centered research and the design of computing-enabled systems. In an increasingly networked world shaped by pervasive technologies, animals – both human and nonhuman – are entangled in complex webs of interaction. ACI 2026 will explore how technology shapes human-animal relationships, how large-scale technological deployments affect animals, and how future systems can be designed responsibly and ethically. The conference also includes work in Animal-Machine Interaction (AMI), exploring interaction and communication between animals and machines, including autonomous systems such as drones and robots. All information about the conference, program, workshops, and participation is available on the ACI 2026 website: www.aciconf.org.
