Sven Kratz

I currently work as a research scientist in Human-Computer Interaction at FX Palo Alto Laboratory (FXPAL). My current research focuses on sensor-based user interfaces with a focus on gestural interactions and free-space input. I also explore spatial interaction techniques in cooperative work environments and augmented spaces as well as user interfaces for robot teleoperation.

Prior to joining FXPAL, I worked as a as a research assistant at Media Informatics and Human-Computer Interaction Group at the University of Munich , Germany, where I obtained my Ph.D. in Computer Science in 2012. From 2008–2011, I worked as a a junior researcher and Ph.D. student within the Quality and Usability Group at Telekom Innovation Laboratories, TU Berlin, Germany. I interned at the Microsoft Applied Sciences Group in the summers of 2010 and 2011. I hold a Diplom degree in Computer Science from RWTH Aachen University, Germany.
