Personal Health Monitoring Using a Smartphone

In this paper, we describe the Well Phone, a smartphone with additional software, that is used as a personal health monitoring device. The Well Phone interfaces various health monitoring devices to the smartphone, and collects physiological data from those devices. It employs novel algorithms that perform statistical analyses, relate sequences of disparate measurements from different devices, and correlate physical activity with physiological measurements. The Well Phone provides feedback to the user by means of visualization and speech interaction, and alerts a caregiver, medical professional, or emergency responder, as needed.
