Publications
As a Research Scientist at Google, I devote to inventing future interactive technologies in 3D graphics, fusing the information from the physical and virtual worlds, and making it interactive, accessible, and useful in VR, AR, and MR. I have published over 25 peer-reviewed publications in top venues of HCI, Computer Graphics, and Computer Vision, including CHI, SIGGRAPH Asia, UIST, TVCG, CVPR, ICCV, ECCV, ISMAR, VR, I3D, Web3D, etc. Please feel free to search keywords / authors / journal / conference below or visit my Google Scholar for more details.
