Body-worn devices that estimate physical behavior have tremendous potential to address key research gaps. However, there is no consensus on how devices and processing methods should be developed and evaluated, resulting in large differences in summary estimates and confusion for end-users. We propose a phase-based framework for developing and evaluating devices that emphasizes robust validation studies in naturalistic conditions.
