Action scores and gesture-based notation in Augmented Reality

Augmented Reality (AR) is becoming, year by year, an established and well-known technological resource. Experimentations and innovative applications are produced in different areas. In music, there already is some use of such a technology in the fields of education and performance. However, the use of AR features as compositional resources has yet to be deeply explored and leaves room for innovative research. In particular, the possibility of notating the gesture in space, instead of on paper or screen, has been only superficially studied. This research focuses on the development of a new prescriptive notation system for gestures that represents extended techniques requiring direct contact between the performer and the vibrating body. Such a system has been implemented in the composition Portale, for small tam-tam, AR environment and live-electronics
