Interactive Spaces. Models and Algorithms for Reality-based Music Applications

Reality-based interfaces have the property of linking the user's physical space with the computer digital content, bringing in intuition, plasticity and expressiveness. Moreover, applications designed upon motion and gesture tracking technologies involve a lot of psychological features, like space cognition and implicit knowledge. All these elements are the background of three presented music applications, employing the characteristics of three different interactive spaces: a user centered three dimensional space, a floor bi-dimensional camera space, and a small sensor centered three dimensional space. The basic idea is to deploy the application's spatial properties in order to convey some musical knowledge, allowing the users to act inside the designed space and to learn through it in an enactive way.
