Interaction and experience design is a rapidly evolving field at the intersection of creativity, technology, and human behavior. It encompasses the full range of ways people engage with digital and digitally enabled products, services, and environments; from mobile applications and enterprise software to AI-enabled interfaces, extended reality experiences, and the physical spaces shaped by connected technology. For students and professionals considering the field, understanding its scope, demands, and what degree-level preparation looks like is essential to making an informed decision about where and how to study.
While UX design is often used as shorthand for this field, interaction and experience design is broader than the visual logic of an app or website. At its core, IXD is the study and practice of how humans engage with designed systems such as digital and digitally augmented physical environments, mixed-reality spaces, and the layered services that span across all.
This broader view reflects where technology is headed. As AI-enabled tools, immersive environments, and connected systems continue to evolve, the boundaries between physical and digital experiences are becoming less distinct. The designers who will lead in this environment need a fundamentally wider frame than screen-based UX alone provides.
Modern IXD practice may include areas such as:
Organizations have come to understand something that was less obvious a decade ago—experience is a competitive variable. A confusing healthcare portal does not just frustrate patients, it affects outcomes. A poorly designed financial services interface does not just annoy users, it erodes trust and drives attrition. A logistics platform that field workers cannot intuitively navigate creates real operational risk.
As AI and immersive technologies become part of more products and services, the complexity of what IXD professionals are asked to develop has increased sharply. Designing AI-powered experiences requires a different kind of rigor than traditional interface design. So does designing for XR environments, where spatial cognition, accessibility, and user safety introduce challenges that flat-screen design never presented.
These shifts have important implications for prospective students deciding where to study. As the field expands to include AI-enabled systems, immersive environments, and more complex service ecosystems, effective IXD programs need to balance strong foundational design principles with exposure to current tools, technologies, and evolving areas of practice. Rather than focusing only on specific platforms or trends, the most valuable programs help students build adaptable skills, critical thinking, and a deep understanding of human-centered design so they can navigate a field that continues to change.
The foundational skills of interaction and experience design are not primarily technical, though technical fluency matters. The most important capabilities IXD practitioners develop are rooted in systems thinking and human-centered design. The ability to hold a complex system in mind, to research and synthesize how real people behave in designed environments, to make and defend design decisions under constraints, and to communicate those decisions across disciplines are essential aptitudes for today’s designers.
Strong IXD programs cultivate several interconnected competencies and skills:
The BS IXD program is built to serve students at different stages and from different starting points:
Prospective undergraduates who want to enter a field at the convergence of technology, creativity, and human behavior, and who want a degree that prepares them for the profession as it exists in real time.
Career changers from adjacent disciplines such as graphic design, psychology, computer science, communications, anthropology, and business, who recognize that IXD is where their existing knowledge and new skills can combine into something more powerful than either alone.
Design students reconsidering their path who want deeper grounding in the research, technology, and strategic dimensions of the field, within an institution built around design education.
These roles span industries: technology, healthcare, financial services, retail, government, education, and any sector actively navigating digital transformation.
