Erik Stolterman May 1, 2021 | 22 min read Erik Stolterman is Professor of Informatics at Indiana University Bloomington, as well as a professor at the Institute of Design at Umeå University, Sweden, where he originates. A prolific scholar of design theory and philosophy, he has co-authored 5 books and more than 150 academic publications with a focus on the design of digital and interactive systems. His work has been immensely useful to mine. In his writings, I find the words I need to articulate my ideas. He writes, among other things, on the relationships between people and products, on the value and ideals of various design research approaches, and on the synergy of design research and design practice. I spoke with him about the basics: How does he know what he knows? And what can designers learn from philosophy?
