We demonstrate how multi-touch hand gestures in combination with foot gestures can be used to perform navigation tasks in interactive systems. The geospatial domain is an interesting example to show the advantages of the combination of both modalities because the complex user interfaces of common Geographic Information System (GIS) requires a high degree of expertise from its users. Recent developments in interactive surfaces that enable the construction of low cost multi-touch displays and relatively cheap sensor technology to detect foot gestures allow the deep exploration of these input modalities for GIS users with medium or low expertise. In this paper, we provide a categorization of multitouch hand and foot gestures for the interaction with spatial data on a large-scale interactive wall. In addition we show with an initial evaluation how these gestures can improve the overall interaction with spatial information.
