Moving Digits: Augmented Dance for Engaged Audience aims to enhance audience understanding and engagement in contemporary dance performances, and to allow to experience dance in an augmented way (even after the performance). The project also aims to empower dancers, choreographers and technicians with further tools for expression, archival and analysis. The use of technology to sense dancers is not new, but the combination of bodily sensing, motion tracking, visualization and sonification is, and especially so in a participatory form. The main aim is to use the advantages of available sensor and mixed media technologies in communicating the body language to the audience. Some of the main motivating questions during the process should be - in which ways can technology translate, transform or extend our bodily existence in space and time? What sort of new effects and meanings can this mediation produce or reveal? How can technology enhance the participatory potential of a dance performance? How can we use technology to enable two-way communication with the audience?
