Techniques for determining one or more physiological properties of a user of a device is disclosed. The techniques include, in part, obtaining one or more vascular-related signals and a first set of data corresponding to one or more inertial sensors. The one or more vascular-related signals and the first set of data correspond to a common time interval. The techniques further include determining one or more motion state categories in accordance with the first set of data, selecting portions of the one or more vascular-related signals based on their corresponding motion state category, and processing the selected portions of the one or more vascular-related signals to determine the physiological properties of the user.
