Eyes-free Exploration of Shapes with Invisible Puzzle

The aim is to reach a wide audience of both sighted and visually impaired users and to engage them, thanks to game elements, in playing over time, so that it is possible to evaluate how the perfor­ mance of each sonification technique is affected by practice.
