The theme of the 16th Biannual Conference of the Italian SIGCHI Chapter (CHItaly 2025) is “Technologies and Methodologies of Human-Computer Interaction in the Third Millennium”. It invites us to reflect on how technological advances continue to redefine our interactions with the digital world.

Over the last two decades, the field of Human-Computer Interaction (HCI) has evolved rapidly, adapting to innovations that have transformed everyday life. Integrating Artificial Intelligence, Augmented and Virtual Reality, Robotics, voice interfaces, wearable devices, and the Internet of Things has brought HCI to the forefront of scientific inquiry, offering novel possibilities and complex challenges. These technologies are not only changing how we use digital systems but also influencing the ways we think, learn, communicate, and interact on a personal, social, and organizational level.

This year’s conference aims to inspire a comprehensive dialogue on how these technologies are reshaping the landscape of HCI and redefining the boundaries of human capabilities. Participants will be invited to engage with questions surrounding ethical implications, accessibility, inclusivity, user experience, and the sustainability of emerging technologies. The theme encourages contributors to share insights on methodologies that adapt to these changes, from user-centred design practices to innovative evaluation methods for complex, adaptive systems.
