摘要:

智能会话代理(ECA)受益于非语言行为,与用户进行自然和有效的交互。手势-伴随着讲话的手和手臂运动-是非语言行为的重要组成部分。手势生成模型已经发展了几十年:从基于规则的方法开始,到主要是数据驱动的方法结束。迄今为止,最近的端到端手势生成方法尚未在与用户的实时交互中进行评估。我们提出了一个概念验证的框架,这是为了方便评估现代手势生成模型的互动。我们展示了一个可扩展的开源框架,它包含三个组件:1)3D交互式代理; 2)聊天机器人后端; 3)手势系统。每个组件都可以被替换,使得所提出的框架适用于研究不同手势模型在与不同通信方式、聊天机器人后端或不同代理外观的实时交互中的效果。代码和视频可以在项目页面https://nagyrajmund.github.io/project/gesturebot上找到。

英文摘要:

Embodied conversational agents (ECAs) benefit from non-verbal behavior for natural and efficient interaction with users. Gesticulation - hand and arm movements accompanying speech - is an essential part of non-verbal behavior. Gesture generation models have been developed for several decades: starting with rule-based and ending with mainly data-driven methods. To date, recent end-to-end gesture generation methods have not been evaluated in a real-time interaction with users. We present a proof-of-concept framework, which is intended to facilitate evaluation of modern gesture generation models in interaction. We demonstrate an extensible open-source framework that contains three components: 1) a 3D interactive agent; 2) a chatbot backend; 3) a gesticulating system. Each component can be replaced, making the proposed framework applicable for investigating the effect of different gesturing models in real-time interactions with different communication modalities, chatbot backends, or different agent appearances. The code and video are available at the project page https://nagyrajmund.github.io/project/gesturebot.
