Method and apparatus for monitoring hydration using a portable communication device

Abstract:

A portable communication device (100) automatically determines user hydration levels while the device is being transmitted. The portable communication device comprises a humidity sensor (120) located by a microphone and touch sensors (124) located on a push-to-talk (PTT) button (110). Data is gathered during PTT switch activation (112). No additional steps are required by the user. Alerts (140) are provided when predetermined dehydration thresholds are approached.
