Molly is a virtual nurse, otherwise known as a ‘health care avatar’, specialized in heart failure care. The avatar is designed to monitor patients, and she is charged with supporting and guiding them in user-friendly manner. Molly asks the patients how they are doing and then verbally instructs them on how to check their vital signs using the accompanying digital scale and blood pressure meter. Once the checks are done, she reports the results and advises patients about any action that needs taking. The system operates via an app on a mobile phone or tablet.
