Idoru() is an interactive sound performance that explores wearable technology and the body as an interface to control sound. The project wishes to address issues of body augmentation through the use of electronic textiles, creating an enhanced hyper-body, that generates useful data, that can be translated into frequencies and thus, generate an interactive soundscape. The system model, is a hybrid between the biological body and its technological augmentations, that without being pervasive to the body itself, allows the performer to extend its biological capabilities, though the use of subtle technologies. Conceptually, the project is influenced by cyberpunk literature as described by William Gibson and the japanese AI performer Rei Toei in his 1996 novel “Idoru”. Idoru, is a female virtual entity, that manifests herself only through her performances, creating this way a unique and personalized experience for her audience.
