His research focuses on building new sensing technologies and systems for AR/VR. Typically, this meant developing new sensing hardware (depth cameras and imaging sensors) alongside practical computer-vision or machine-learning algorithms and techniques for these technologies. He was at Xerox PARC in 2000-2002, and obtained his PhD from the Mixed Reality Lab at the University of Nottingham, UK, in 2004. In 2009, he was named one of the TR35, an annual list published by MIT Technology Review magazine, naming the world’s top 35 innovators under the age of 35. He has published over 120 research papers (see DBLP & Google Scholar), and more than 120 patents. His work has led to products and projects such as the Microsoft Touch Mouse, Kinect for Windows, Kinect Fusion, and most recently HoloLens and Holoportation.
