CONFIRMING SLEEP BASED ON SECONDARY INDICIA OF USER ACTIVITY

Abstract:

In some implementations, a provisional determination that a user of a first device is awake may be based on data indicating that the first device is being used. Also, sleep sounds associated with a human sleeping may be detected, and sleep sound information corresponding to the user may be obtained. Next, the detected sleep sounds may be compared to the sleep sound information, and a determination may be made as to whether the detected sleep sounds are attributable to the user based on the comparison of the detected sleep sounds and the sleep sound information. In addition, the provisional determination that the user is awake may be revised to indicate that the user is sleeping in response to a determination that the detected sleep sounds are being performed by the user in order to provide a more accurate sleep determination for the user.
