Activity-aware heart sensing in mobile healthcare

This work designs, implements, and evaluates an activity-aware heart sensing framework based on mobile devices, called AA-Heart, which consists of two major components: the front-end mobile platform collecting user's heart and context data, and the back-end web server where the data can be visually displayed, screened and analyzed, and shared with user's permission. Using the mobile devices, AA-Heart can monitor heart continuously and send the heart data to medical staff in a real-time way. Specially, AA-Heart enables doctor to make a positive diagnosis of user's heart conditions. Since mobile devices are very constrained in energy resource, we design a semantics-based model to achieve balance of energy efficiency and application fidelity.
