我们展示了WITAS对话系统的第一个演示版本，用于与自主移动的机器人进行多模态对话，并激发了目前正在开发的版本II的几项创新。人机交互设置被认为是提出了新的挑战，对话系统工程师，相比以前的工作，在对话系统下的旅行规划范式，在对话必须是异步的，混合主动，开放式的，并涉及一个动态的环境。我们在WITAS机器人直升机或UAV（“无人驾驶飞行器”）的对话界面中处理了这些一般性问题。1我们提出了这个系统及其背后的建模思想，然后激发了对系统第二版的修改，包括更丰富的结构化对话状态以及在任务、能力和世界状态模型上使用自动推理系统。我们认为，这些类型的增强是至关重要的会话系统的未来发展。
We present the first demonstration version of the WITAS dialogue system for multi-modal conversations with autonomous mobile robots, and motivate several innovations currently in development for version II. The human-robot interaction setting is argued to present new challenges for dialogue system en-gineers, in comparison to previous work in dialogue systems under the travel-planning paradigm, in that dialogues must be asynchronous, mixed-initiative, open-ended, and involve a dynamic environment. We approached these general problems in a dialogue interface to the WITAS robot helicopter, or UAV (‘Un-manned Aerial Vehicle’). 1 We present this system and the modelling ideas behind it, and then motivate changes being made for version II of the system, involving more richly structured dialogue states and the use of automated reasoning systems over task, ability, and world-state models. We argue that these sorts of enhancement are vital to the future development of conversational systems.
