Steven K. Feiner is Professor of Computer Science at Columbia University, where he directs the Computer Graphics and User Interfaces Lab. His research interests include human–computer interaction, augmented reality and virtual reality, 3D and 2D user interfaces, automated design of graphics and multimedia, mobile and wearable computing, health applications, computer games, and information visualization. Prof. Feiner is a Fellow of the ACM and the IEEE and a member of the CHI Academy. He is the recipient of the ACM SIGCHI 2018 Lifetime Research Award, the IEEE ISMAR 2017 Career Impact Award, the IEEE VGTC 2014 Virtual Reality Career Award, and an ONR Young Investigator Award. Together with his students, he won the IEEE ISMAR 2019 Impact Paper Award, the ISWC 2017 Early Innovator Award, the ACM UIST 2010 Lasting Impact Award, and best paper awards at ACM UIST, ACM CHI, ACM VRST, IEEE ISMAR, and IEEE 3DUI. His lab created the first outdoor mobile augmented reality system using a see-through head-worn display and GPS in 1996, and has pioneered experimental applications of augmented reality and virtual reality to fields as diverse as tourism, journalism, archaeology, maintenance, construction, and medicine. Prof. Feiner has served as program chair or general chair for over a dozen ACM and IEEE conferences, and is coauthor of two editions of Computer Graphics: Principles and Practice and of Introduction to Computer Graphics (Addison-Wesley).
