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.

We invite submissions of research papers, both long and short, that contribute to the field of Human-Computer Interaction (HCI).

• Long Papers: These should present original, substantial research that advances HCI. Submissions must provide sufficient methodological and technical detail to ensure thorough scrutiny and reproducibility. Results should adhere to established scholarly standards, and authors are expected to discuss explicitly the implications of their findings for the field.
• Short Papers: These should introduce innovative or thought-provoking research, or novel applications within HCI. Evaluation will focus on the originality and relevance of the work rather than on comprehensive technical validation or extensive research studies.

Paper Format and Submission Guidelines

All paper submissions must be prepared in English, and authors are required to use the ACM single-column submission template for all submissions. The recommended page limits are as follows:

• Long Papers: A maximum of 10 pages(*) for long papers, excluding references
• Short Papers: A maximum of 6 pages(*) for short papers, excluding references

(*) page limit is in terms of double column format.

ACM single-column submission templates are available for both Word and LaTeX:

If you choose to use LaTeX, follow the instructions under the section “The ACM Article Template: Using LaTeX“. For complete guidelines on ACM formatting, please consult the ACM website. Submissions must be uploaded in PDF format via Easy Chair.
