本书涵盖了从医疗保健到教育的八个应用领域，展示了六十多件作品——不是你在杂志或网上看到的那种，而是那些对全世界的社区和生活产生真正影响的作品。书中介绍的每件作品没有像商业设计那样以顾客为导向，而是伸出援手的设计师、积极参与的社区和帮助人们实现想法的技术共同作用的结果。从南非的一个通过游乐场供电的水泵到一个DIY的廉价手机，这些开创性的作品中的每一件作品都通过引人入胜和积极向上故事、揭示每种设计方法背后的机制和动机的图表，以及赞美这些尝试的人性化的摄影来呈现。

Structured into eight areas of application, from healthcare to education, this book showcases over sixty projects – not the kind you see in glossy magazines or online, but the ones that have made a genuine difference to communities and lives around the world. Rather than being client-driven, as commercial design often is, each project here is the result of designers who reach out, communities who get involved and the technologies that helping people to realize ideas together. From a playground-powered water pump in South Africa to a DIY budget cellphone, each of these groundbreaking projects is presented through fascinating and life-affirming stories, diagrams that reveal the mechanisms and motivations behind each design approach, and photography that celebrates the humanity of the endeavour.
