论文摘要
我们提出了一种新颖的方法，用于在共享虚拟环境中生成合理的言语相互作用和虚拟人类的化身和用户头像。 Sense-Plan-ask或Spa在命题计划和自然语言处理方面扩展了先前的工作，以使代理商能够使用不确定的信息来计划，并利用问题和回答与其他代理商和化身的对话，以获取所需的信息并完成其目标。代理人还可以使用自然语言来回答头像和其他代理商的问题，从而实现实时多代理多瓦塔尔通信环境。 我们的算法可以在交互，移动，沟通，计划和重新启动下模拟数十个虚拟代理。我们发现，我们的算法创造了较小的运行时成本，并且使代理商比没有能力利用自然语言交流的代理人更有效地完成目标。我们在一组模拟基准上展示了定量结果，并详细介绍了为评估SPA产生的虚拟相互作用的合理性的初步用户研究结果。总体而言，我们发现参与者更喜欢水疗中心，而不是84％的响应中的先前技术，包括自然语言相互作用的合理性和这些相互作用的积极影响，包括重大好处。
We present a novel approach for generating plausible verbal interactions between virtual human-like agents and user avatars in shared virtual environments. Sense-Plan-Ask, or SPA, extends prior work in propositional planning and natural language processing to enable agents to plan with uncertain information, and leverage question and answer dialogue with other agents and avatars to obtain the needed information and complete their goals. The agents are additionally able to respond to questions from the avatars and other agents using natural-language enabling real-time multi-agent multi-avatar communication environments. Our algorithm can simulate tens of virtual agents at interactive rates interacting, moving, communicating, planning, and replanning. We find that our algorithm creates a small runtime cost and enables agents to complete their goals more effectively than agents without the ability to leverage natural-language communication. We demonstrate quantitative results on a set of simulated benchmarks and detail the results of a preliminary user-study conducted to evaluate the plausibility of the virtual interactions generated by SPA. Overall, we find that participants prefer SPA to prior techniques in 84\% of responses including significant benefits in terms of the plausibility of natural-language interactions and the positive impact of those interactions.
