Claim:
1. A method for determining measurement confidence for data collected from a sensor of a wearable device, comprising: determining that a first sample voltage of the wearable device is less than a first threshold voltage; in response to determining that the first sample voltage is less than the first threshold voltage, determining that a second sample voltage of the wearable device is greater than a second threshold voltage; in response to determining that the second sample voltage is greater than the second threshold voltage, calculating a signal quality metric indicative of data measured by the sensor of the wearable device over a test period; in response to calculating the signal quality metric indicative of the data measured by the sensor of the wearable device over the test period, determining that the signal quality metric is greater than a measurement threshold indicative of a minimum signal quality metric; and in response to determining that the signal quality metric is greater than the measurement threshold indicative of the minimum signal quality metric, determining that the wearable device is worn by a user.
