Multi-Modal Spatial Querying
TLDR
We use two concurrent communication channels—graphics and speech—to construct a multi-modal spatial query language in which users interact with a geographic database by drawing sketches of the desired configuration, while simultaneously talking about the spatial objects and the spatial relations drawn.
