Mike Chen's Research

Our paper on applying machine learning + wearable accelerometers to recognize free-weight exercises will be presented at Ubicomp 2007.

I recently joined a stealth-mode startup, Ludic Labs, in San Mateo, CA. At Intel Research Seattle, I led two mobile phone/ubicomp projects that led to publications at Ubicomp (4), MobiSys (2), UIST, HotOS, and HotMobile:

Privacy Observant Location System (POLS), a client-side GSM/WiFi location system
MyExperience, a system for in-situ tracing and capturing of user feedback on mobile phones.

My mobile phone research focuses on rapid development of context-enhanced apps on cell phones and novel uses of personal context such as location, physical activities (e.g. running, cycling), and communication (e.g. phone calls, email, SMS).

MyExperience: context-enhanced in-situ survey on mobile devices.
MyRoute: personalizing directions based on personal travel patterns.
Voting with Your Feet: inferring place preference based on visit patterns.
Metropolitan-scale client-side positioning using GSM phones

During my years at UC Berkeley, my advisor was Prof. Eric Brewer, co-founder of Inktomi. I also worked closely with Prof. Dave Patterson, currently the ACM President, Prof. Armando Fox, and Prof. Marti Hearst on the following projects:

ROC - recovery-oriented computing.
Ninja - infrastructure for scalable, composable Internet services.
Cha-Cha - exploiting hyperlink structure to provide search result context.
