  We describe the adaptation and refinement of a graphical user interface
designed to facilitate a Wizard-of-Oz (WoZ) approach to collecting human-robot
dialogue data. The data collected will be used to develop a dialogue system for
robot navigation. Building on an interface previously used in the development
of dialogue systems for virtual agents and video playback, we add templates
with open parameters which allow the wizard to quickly produce a wide variety
of utterances. Our research demonstrates that this approach to data collection
is viable as an intermediate step in developing a dialogue system for physical
robots in remote locations from their users - a domain in which the human and
robot need to regularly verify and update a shared understanding of the
physical environment. We show that our WoZ interface and the fixed set of
utterances and templates therein provide for a natural pace of dialogue with
good coverage of the navigation domain.
