ACM is a premier publisher of computing research, with its Digital Library serving as one of the largest and most respected archives of computer science literature. The organization also sponsors more than 170 events annually, many of which are considered top-tier in their respective subfields. In addition, ACM supports a wide range of SIGs, including SIGCHI (Human-Computer Interaction), SIGGRAPH (Computer Graphics), and SIGPLAN (Programming Languages), each of which drives progress in specialized areas of computing.
Being published or referenced in an ACM venue is widely recognized as a mark of academic rigor, relevance, and credibility within the computing and technology communities.

About the ACM Designing Interactive Systems Conference
The ACM Designing Interactive Systems (DIS) Conference is one of the premier international gatherings focused on Human-Computer Interaction (HCI) and design research. Organized by ACM SIGCHI—the Special Interest Group on Computer–Human Interaction—DIS is distinctively design-oriented, bridging the gap between technical HCI research and real-world design practice. It draws a diverse mix of participants including UX researchers, interaction designers, social scientists, technologists, and both industry practitioners and academics.
Key themes often explored at DIS include interactive and digital system design, participatory and co-design methods, speculative and critical design, community engagement and social innovation, AI ethics and responsible technology, and tangible, embedded, and immersive interfaces. This rich diversity of topics reflects the conference’s commitment to pushing boundaries at the intersection of design, technology, and society.
Renowned for its selectivity and rigorous peer-review process, DIS is known as a hub for interdisciplinary innovation. It serves as a platform where cutting-edge ideas converge and evolve. Typical attendees include researchers and designers from top universities, research institutions like Microsoft Research and Google Research, nonprofits, startups, and international development organizations.
