I am an associate researcher in the Wireless and Networking Group at Microsoft Research Asia (MSRA). I received B.E and M.E (both with honors) from Automation Department, Tsinghua University in Beijing in 2002 and 2005.

My research interests include Mobile Computing and Wireless Networks and Signal Processing. Actually, I am interested in any novel techniques and systems that can enhance collaboration among users on any networks, especially distributed forms.

Projects

BeepBeep seeks a high-accuracy ranging technique, without leveraging any pre-planned infrastructure or special hardware/system modification. It should be a software-based solution and uses only the most basic set of commodity hardware so that it is readily applicable to many low-cost sensor platforms and COTS mobile devices. The key idea is to use the pair-wise the elapsed time of arrival (ETOA) of sound signals between the two devices to infer the distance. We have implemented BeepBeep prototype on Windows 5.0+ mobile phones and demonstrated that it can achieve around one or two centimeters accuracy within a range of more than ten meters. More information about BeepBeep can be found in this page.

Point&Connect (P&C) offers an intuitive and resilient device pairing solution on standard mobile phones. Its operation

follows the simple sequence of point-and-connect: she simply points her phones toward the intended target, and it is done for pairing. The key idea is to measure maximum distance change based on acoustic signals to capture the user intention and pick the right device among many others nearby. We have implemented P&C in Windows Mobile phones and demonstrated that it is acool and effective way to do device pairing. More information about Point&Connect can be found in this page.
