What does it take to create digital experiences which positively impact our health? How do user experience requirements change as digital evolves from a method for simply self-tracking health metrics to becomes a platform for diagnosing and even treating conditions. What are the requirements from different stakeholders, from end user patients to their casual networks of supporting friends and family, prescribing clinicians and the insurers and national health services which manage the costs. Hosts Marek Pawlowski and Alex Guest discuss examples, explore design principles and user research challenges.
