Abstract

The concept of gamified interactive models and its novel extensions, such as playification, has been widely approached in order to engage users in many fields. In fields such as HCI and AI, however, these approaches were not yet employed for supporting users to create different forms of artworks, like a musical corpus. While allowing novel forms of interactivity with partially-autonomous systems, these techniques could also foster the emergence of artworks not limited to experts. Hence, in this paper we introduce the concept of meta-interactivity for compositional interfaces, which extends an individual's capabilities by the translation of an effort into a proficiency. We present how this approach can be effective through a novel system that enables non-experts to compose coherent musical pieces through the use of imagetic elements in a virtual environment. We conduct experiments with a population of musical experts and non-experts, showing that non-experts were able to learn and create high-quality musical productions through our interactive approach.
