100 million adults in China are affected by chronic obstructive pulmonary disease (COPD), yet less than 7% are properly diagnosed. GlaxoSmithKline set out to resolve this shortfall by turning a mobile phone into a selftesting diagnostic tool. Inspired by traditional Chinese art form of blow painting, the brand worked with We Chat, China’s most popular social media channel to create the Breath of Life app. Users simply pick out an artistic tree type and color and then blow onto the phone to create a rendition of their chosen tree. The app then uses the phone’s microphone to determine any level of COPD by the volume of breath blown in a second versus the total volume. The size of the produced tree represents the lung’s capacity and any need to seek out medical examination.
