Wearable device body detection

Abstract: Wearable devices to monitor user biometrics have become prevalent in use. Accuracy of those devices has become more important, as has battery conservation. Of particular importance to both accuracy and battery conservation is accurately determining when the device is worn or within a proximity of a user such that biometric data can be determined, and when the device is not worn or within a proximity of the user, such that biometric data can be determined. A failure to accurately detect the status of the device at any point will result in degraded user experience, such as missing biometric data, and lost battery life. Increasing the difficulty of this problem is that accurately detecting the status of the device is more difficult for some skin tones.
