Eucalyptus: Integrating Natural Language Input with a Graphical User Interface
Abstract
This report describes Eucalyptus, a natural language (NL) interface that has been integrated with the graphical user interface of the KOALAS Test Planning Tool, a simulated Naval air combat command system. The multimodal, multimedia interface handles both imperative commands and database queries (either typed or spoken into a microphone) while still allowing full use of the original graphical interface. In this way the precision and consistency of direct manipulation is balanced and augmented by the descriptive power and reduced redundancy of NL. The two input media used together yield such powerful interaction techniques as deixis (simultaneous speech and pointing) and the ability to use mouse clicks and verbal referring expressions interchangeably. Finally, the system's discourse handling capability allows abbreviated NL follow-ups (anaphora and ellipsis) to receive full interpretations based on the prior interaction context, whether verbal or graphical.
