Activity Monitors: Some interesting data and challenges

Fri, Feb 3 2017 - 12:00pm to 1:00pm
Seeley Mudd Room 206

A surprising number of people use some sort of activity monitor to assess aspects of daily physical activity, sedentary behavior, and sleep. This non-technical talk will have two parts. In the first part, I will describe how the monitors work.More specifically, this will include an introduction to the data that the monitors collect, an overview of the types of statistical models and algorithms that the monitors apply to those data, and a summary of how those algorithms are calibrated. In the second part of the talk, I will discuss aspects of activity monitoring in more detail, including: (1) the sedentary sphere, (2) step detection methods, and (3) what makes a good calibration? (This is based on joint work with a number of people, especially Professor Patty Freedson, Department of Kineseiology at UMass-Amherst.)
