Method for estimating device fit using physiological data

Abstract

Methods and systems are provided for assisting a user of a wearable biosignal monitoring device () in adjusting the device to achieve optimum fit and positioning. The biosignal monitoring devices considered use integrated bio sensors () to monitor the user's physiological activity for various purposes such as tracking daily activity patterns, determining mood, and monitoring sleep stages, among others. It is determined either during device setup or during primary use of the device whether the current fit and positioning of the device () enable the bio sensors () to properly sense the physiological signals needed for the device to perform its primary function. The user is then informed either after initial device setup whether adjustments need to be made in order to optimize device function during primary use, or is informed after primary use whether adjustments need to be made in order to improve device function during future primary use.
