Recent research has demonstrated the benefits of mixed realities for information visualisation. Often the focus lies on the visualisation itself, leaving interaction opportunities through different modalities largely unexplored. Yet, mixed reality in particular can benefit from a combination of different modalities. This work examines an existing mixed reality visualisation which is combined with a large tabletop for touch interaction. Although this allows for familiar operation, the approach comes with some limitations which we address by employing mobile devices, thus adding tangibility and proxemics as input modalities.
