Graffito: crowd-based performative interaction at festivals

Crowd-based events are generating new forms of crowd-based performative interaction. Nightclubs and festivals are at the cutting edge of crowd-based interaction with ubiquitous computing. The social capital of crowd-based interaction is not well understood and is usually limited to one-off events. Our intention is to explore the possibility for generating a lifelong contextual footprint of crowd-based performative interaction. In this paper, we present and discuss two case studies of designing applications for crowd-based performative interaction at two large-scale festivals and reflect on their implications for design.
