摘要: This paper compares the efficiency of using a standard direct-manipulation graphical user interface (GUI) with that QuickSet pen/voice multimodal for supporting military task. In this task, places units and control measures (e.g., various types lines, obstacles, objectives) on map. Four personnel designed entered their own simulation scenarios via both interfaces. Analyses revealed led to an average 3.5-fold speed improvement in entity creation time, including all error handling. The mean time repair errors also was 4.3 times faster when interacting multimodally. Finally, subjects reported strong preference interaction. These results indicate substantial advantage over GUI-based interaction during map-based tasks.
