abstract = {Affordances manifest possibilities of interaction with a spoken dialog
system. For example, the act of asking a question affords to the recipient the
possibility of answering. In the system we present, the observable act of maneuvering
affords the possibility of controlling a motion. Our system thus uses the affordance
principle to shape the interaction: to trigger the usage of instructions that are easy
to understand and process, the system gives immediate visual feedback to afford
user commands that can then be reacted upon. This tightening of the interaction
loop requires an incremental processing paradigm to allow fast reactions and to be
able to alter ongoing system actions. Our system is a hybrid of incremental and
non-incremental processing components, combining conventional, state graph-based
processing, which has the advantage of widely available toolkits and well-understood
dialog management, with incremental dialog processing which allows for the tight
feedback loop that provides for quick reactions. We tested our approach in a small
user study and found that users used simpler and setting-independent commands
more often and were more efficient when faced with the affordance-based version of
our system.},
