Moori is an interactive audience-participatory multi-media performance system. By innovations in network-based personal mobile devices, users collaboratively generate stories, animation, and sound. The dialogue between the performer and audience members results in a dramatic narrative and a real-time audio-visual composition. Moori allows audience members to take part actively in narrative-building, which brings visuals and sound in a performance. Users tell stories in response to guided questions by the performer by interacting with multiple modes of messaging on mobile phones and portable smart devices. As audience members input data through their personal device, the user data is processed to generate audio and graphics while creating a larger narrative. This collaboration creates dialog between the performer and audience members and suggests new possibilities that can exist through the combination of algorithmic animation, audio and language.
