In this paper we present some of the challenges we approached in order to design and develop interactive experience environments in textile. Our interactive environments are created to facilitate communication on equal terms through music, between children with severe disabilities and their families. We call these environments “fields” because of their openness towards many interpretations, interaction forms and activity levels. We present some of the problems, experiments and explorations we made in textile, when designing these fields. We show how we designed to motivate musical actions, like playing an instrument, improvising with the field as a co-musician, and experiencing it as a “soundscape”.
