Keynote

It's Time to Focus on the Apps!


Jeff Dean

AJ Brush (Microsoft Research)

Mobile phones offer fascinating opportunities to sense information and interact with users. Past research has been critically important to demonstrate that it is possible to sense a variety of human activities and contexts, address energy and other pragmatic concerns, and to prototype a range of applications that are enabled by phone sensing. In this talk, drawing from my experience building mobile context sensing applications, I will argue that as a research community it's time to move the focus from general purpose enabling research to application-driven research. I have two primary reasons for this argument. First, the usage context of an application directly impacts the relative importance of a number of factors including energy efficiency and recognition accuracy required of any inference. Second, building mobile context sensing applications currently requires expertise not only in developing applications, but also in sensing and machine learning, not to mention collecting large amounts of data to train models. In our own work, we have found it quite difficult to build on past research, especially when our goal has been building novel experiences, not advancing basic research in activity recognition. In addition to showing past and ongoing research on mobile sensing applications, I will present some ideas for ways the community might work together to enable application-driven research including sharing annotated sensor data, creating a shared set of basic logging and activity recognition algorithms, or running a "grand challenge" for applications in a specific domain. My aim is to for the presentation to be very interactive and hope you will come with your own ideas and feedback.
