American designer Aza Raskin proposes a design renaissance in healthcare, making it easier and more enjoyable.
Whose fault is it that video recorders are hard to programme, he asks? And why do we complete so few courses of antibiotics - with all the terrible individual and social consequences?
His answer in both cases is that the products are badly designed, and they don't take into account how human beings actually behave.
He argues that by applying cognitive psychology, design, and feedback loops to some of our most intractable medical problems, we can dramatically improve our health.
Four Thought is a series of talks which combine thought provoking ideas and engaging storytelling.
