About
Xiaojun Bi is a Human-Computer Interaction research scientist at Google in Mountain View, California. His research focuses on building interactive systems, implementing interaction techniques, and studying fundamental issues of user interface design especially on mobile devices. He has pioneered a number of techniques for mobile text entry systems, pen and touch based interactive systems, and large display interaction. His recent innovations such as keyboard correction & completion algorithm (CHI 2013) , bimanual gesture typing (UIST 2012), personalizing language models for text entry (CHI 2015) have been integrated into the Android keyboard, used by more than 100 million users. The keyboard evaluation system, Octopus (CHI 2013) has been widely used in the product development. Mobile Interaction Research at Google, a Google Research blog article highlights some of his recent research integrated into the Google products. Xiaojun Bi has authored 20 publications in the premier HCI publication venues such as CHI, UIST, and Human Computer Interaction Journal, and 20 US patents (11 issued and 9 pending). His research papers have received awards at CHI, the flagship conference in HCI. His paper studying the speed-accuracy tradeoff of finger touch input (FFitts Law, CHI 2013) won the Google 2013 Influential Paper Award. Xiaojun Bi is active in the HCI academic community. He constantly serves as an Associate Chair on the CHI and UIST program committees, and organizes/co-organizes CHI workshops to prompt research in computational interaction design and text input technology. He is now co-editing the book Computational Interaction Design. He was a program co-chair for Chinese CHI 2015, and now is a general co-chair for Chinese CHI 2016. Xiaojun Bi earned his Ph.D. from the Department of Computer Science at the University of Toronto. He received his Master's and Bachelor's degrees from Tsinghua University. He won the first place in the National Mathematical Olympiad (China) in his home province when he was a high school student, recruited by Tsinghua University with national college entrance examinations waived.
