Choreomorphy is a Unity-based interactive application that supports reflective dance improvisation through the use of MoCap technologies. The design idea is that different avatars and visualisations of movement highlight different aspects and eventually trigger different qualities and patterns of moving, which is meaningful from both a pedagogic as well as creative and aesthetic perspective. By wearing an inertial motion capture suit, the user can visualise his/her movements in real time in the form of a 3D avatar with related customisable motion effects, allowing to focus on specific aspects of the movement such as traces, or volumetric space. The tool allows to change and customise the visualization by switching among different avatars and settings in real time, facilitating self-reflection and experimentation. The application also allows to load pre-recorded MoCap data and watch them in a variety of avatars, environments and effects or even in augmented reality through the HoloLens.
