AirFlow: designing immersive breathing training games for COPD

Chronic Obstructive Pulmonary Disease (COPD) refers to a collection of lung diseases that result in breathing difficulties. In some cases, the symptoms of COPD can be reduced, by engaging in breathing exercises. Technology can support, and we are developing AirFlow, a suite of interactive computer games, to guide breathing exercises and promote learning. To establish requirements, we interviewed 20 people with COPD, in China, to understand their use of breathing exercises, and learn how technology might fit their lifestyle. The findings informed our design goals. We outline a prototype system, where respiration rate, waveform, and amplitude are captured and used to control a virtual environment. The system will guide users through breathing exercises, and provide training instructions, using a series of games. The immersive environment aims to support a fun and motivating experience, therefore underpinning user confidence.
