How to connect patients to their illness and the medical staff, while complying to the constraints of patient management in the care system? This project, led at the Polyclinic Baudelaire (APHP Saint-Antoine) with Prof. Jacques Lebas, developed into tools to reduce uncertainty and facilitate decision-making. It aims to humanize communication tools to promote cooperation and understanding by becoming virtually invisible in the chain of care. Thus facilitating and improving interactions between patients, practitioners and the health care system. In this particular context, a designer has to reveal and create touchpoints by juggling with interaction design and information representation to enable a satisfying and efficient user experience, be it patient-wise or practitioner-wise. Due to the variety of user expectations, the whole design process had to be agile and versatile enough to enable updates on-the-fly without interruption and under constant evaluation. Eventually, the “design” has to completely vanish to make way for a flexible and appropriable service.
