Holophonor: On the Future Technology of Visual Music

This chapter discusses the progression of visual music and related audio-visual artworks through the 20th Century and considers the next steps for this field of research. The principles of visual music are described, with reference to the films of early pioneers such as John Whitney. A further exploration of the wider spectrum of subsequent work in various audio-visual art forms is then given. These include visualisations, light synthesizers, VJ performances, digital audio-visual artworks, projection mapping artworks, and interactive visual music artworks. Through consideration of visual music as a continuum of related work, the authors consider the Holophonor, a fictional audio-visual instrument, as an example of the ideal visual music instrument of the future. They conclude by proposing that a device such as the Holophonor could be constructed in the near future by utilising inter-disciplinary approaches from the fields of HCI and affective computing.
