Título: “Topos” toolkit for pure data: exploring the spatial features of dance gestures for interactive musical applications
Even though the relationships of music and dance appear to be evident in most of cultural contexts, the two modalities tend to be seen as two separated cultures. However, the im- pact of technologies in the culture of information societies created an interesting momentum: The unprecedented ac- cess to all sorts of combinations of music, image, video and media streams created a scenario that demands more interactive and expressive multimodal experiences. How to support the demands for richer music-movement inter- actions? How to translate spatiotemporal qualities of hu- man movement into relevant features for music making and sound design? In this paper we study the realtime interac- tion between choreographic movement in space and mu- sic, implemented by means of a collection of tools called Topos. These tools – developed in the Pure Data platform – provide a number of feature descriptions that help to map quality of dance gestures in space to music and other me- dia. The features are based concepts found in the literature of cognition and dance, which improves the computational representation of dance gestures in space. The concepts and techniques presented in the study introduce new prob- lems and possibilities for multimedia applications and per- formances involving the dance and music interaction.
