When these "things" (in the growing Internet of Things healthcare ecosystem) are beautifully designed to mesh into peoples' life-flows, they can make real differences to people's individual health, and in aggregate, drive public health. The key best practice is radical user-centered design: being passionate about the ethnographic research that informs how people actually "live, work, play, pray and learn," in the context of their personal values.
That's the promise of the best user-centered design for health and wellbeing, for all people. One area where digital health can scale scarce resources is in mental health. A fine example of digital technology bridging the gap between patient/consumer and health care providers is The Big White Wall in the UK. This platform enables people to record their mood, network and interact with peers dealing with behavioral health challenges, and touch base with health care providers. The model has proven to be cost-effective, saving the National Health Service at least 340 pounds a year for each patient using the service.
