In this paper we motivate the use of
qualitative spatial actions
as the fundamental unit in processing user route instructions. The spatial action model has been motivated by an analysis of empirical studies in human-robot interaction on the navigation task, and can be interpreted as a conceptual representation of the spatial action to be performed by the agent in their navigation space. Furthermore, we sketch out two distinct models of interpretation for these actions in cognitive robotics. In the first, the actions are related to a formalized
conceptual user modeling
of navigation space, while in the second the actions are interpreted as
fuzzy operations
on a voronoi graph. Moreover, we show how this action model allows us to better capture the points at which user route instructions become out of alignment with a robot’s knowledge of the environment through a number of examples.
