This is the project I'm currently working on.

This is my house
For several years my work has been centered on the writing itself of choreography – writing that implies the creation of special signals used to compose the dance ahead of the rehearsals with the dancers – and on the integration in this writing of computerized devices of disturbance and re-generation of the pre-written composition in real time. The goal of this research is to invite the performer to co-create an open score.

For "This is my house" the five dancers pilot the process of modification of the choreographic score by their breath and by slow movements – thanks to the collecting system developed by the IRCAM – which shows up on LCD screens placed above. Therefore, the technology – the computer device at the heart of the relations between time and spaces – allows the structure of situations, of original contexts that the dancers interpret, as the piece develops and unfolds.

This is a performance for 5 dancers wearing Wi-Fi sensors (accelerometers, optical-flex, standard flex and breath sensors). A dance score (Laban notation customized by Myriam Gourfink) is generated in real-time driven by the interpretation of the dancers and displayed on 12 LCD monitor facing the floor on a structure over the dancers. A computer is in charge of receiving the sensor data and performs various kind analysis in order to trigger and generate the score to be displayed.

analysis performed on the sensors
- cyclicity detection through generalized autocorrelation
- synchronicity between dancers for different sensors
- activity of each dancer
- phrase recognition using Hidden Markov Models so that dancers have control over the time of the performace.

all the analysis is performed using the MnM/FTM library for MaxMSP.
