For example, the act of asking a question affords to the recipient thepossibility of answering. In the system we present, the observable act of maneuveringaffords the possibility of controlling a motion. Our system thus uses the affordanceprinciple to shape the interaction: to trigger the usage of instructions that are easyto understand and process, the system gives immediate visual feedback to afforduser commands that can then be reacted upon. This tightening of the interactionloop requires an incremental processing paradigm to allow fast reactions and to beable to alter ongoing system actions. Our system is a hybrid of incremental andnon-incremental processing components, combining conventional, state graph-basedprocessing, which has the advantage of widely available toolkits and well-understooddialog management, with incremental dialog processing which allows for the tightfeedback loop that provides for quick reactions. We tested our approach in a smalluser study and found that users used simpler and setting-independent commandsmore often and were more efficient when faced with the affordance-based version ofour system.}, language = {en} } @misc{PaetzelSchlesingerPricopetal., author = {Paetzel, Maike and Schlesinger, Philipp and Pricop, Mircea and Comaneci, Radu and Baumann, Timo and Menzel, Wolfgang}, title = {Inkrementelle und zustandsbasierte Verarbeitung in einem hybriden Sprachdialogsystem}, language = {en} }
