Interactive sound is enabled by interactive systems that track the user's activity and provide sonic feedback in real-time. The chapter's focus is on how the experience of different walking aspects can be supported depending on decisions in design of interactive sound. The chapter starts by arguing that interactive systems can be designed to promote different aspects of the activity at hand. It then provides reasons for using sonic feedback in design for physical activities and explains the basic technical components to implement interactive sound. The chapter continues with analysis of design approaches that use interactive sound to support different walking aspects including: navigation, the exploration of the environment and optimization of body movement. This way interdependencies are elucidated between: the specific walking aspect that is supported, the walking setting, decisions on walking information tracked and sonic material used. The second part elaborates on GangKlang, a concept to design interactive sound with the aim to enhance walking experiences in daily life. Finally, challenges and opportunities of designing interactive sound for walking in everyday life are discussed.en004book article
