The Animal-Computer Interaction International Conference 2026 (ACI 2026) invites contributions for its thirteenth edition. The conference seeks theoretical, methodological, empirical, and ethical work that advances dialogue around animal-centered research and the design of computing-enabled systems. ACI brings together perspectives from computer science, informatics, engineering, interaction design, animal behavior and welfare science, veterinary science, ecology, sociology, philosophy, and related disciplines, with the aim of further developing Animal-Computer Interaction as a field. In an increasingly networked world shaped by pervasive technologies, animals – both human and nonhuman – are entangled in complex webs of interaction. These interactions may be direct or indirect, physical or cognitive, distributed or dyadic, synchronous or asynchronous. Contributions are encouraged that critically examine 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 welcomes submissions in Animal-Machine Interaction (AMI), which explores interaction and communication between animals and machines, including autonomous systems such as drones and robots. AMI focuses on designing machines that benefit animals and safeguard their interests, supporting survival and well-being. The submission deadline for Research Papers and Emerging Work Papers has been extended by two weeks and is now May 15, 2026. The deadline for Workshop Proposals remains unchanged at June 1, 2026. All submissions will be peer-reviewed. Further information is available at www.aciconf.org, and submission details can be found at www.aciconf.org/call-for-contributions.
