Workshop on Perceptive Animated Interfaces and Virtual Humans

感知动画界面代表了新一代人机交互，其中人与机器交互就像人在特定任务域中相互交互一样。这些界面结合了虚拟的栩栩如生的三维动画计算机角色，这些角色在特定的任务领域（如学习和训练）展示了专家的智慧和行为。虚拟人定位于用户，在用户说话时提供实时反馈（如点头、微笑、困惑的表情），解读用户的听觉和视觉行为，推断用户的意图和认知状态，并通过自然的面对面对话与用户进行敏感有效的沟通，实现任务目标。感知动画界面和虚拟人研讨会的目标是将来自科学学科的感兴趣的研究人员聚集在一起，帮助概念化开发包含虚拟人的感知动画界面所涉及的挑战，考虑可能的研究议程和形成一个社区所需的步骤，这个社区将共同努力，促进朝着共同的研究目标前进。参与者包括来自人类交流、人机界面设计、人类语言技术、计算机视觉、计算机动画、认知科学和其他相关研究领域的科学家。研讨会活动包括评估相关学科的当前理论和实践，定义研究目标和目的，评估系统架构，确定可以将原型系统开发为研究测试平台的任务域，以及确定执行建议工作所需的关键基础设施。感知动画界面的发展有望通过提供更自然和有效的通信体验来彻底改变人机交互，并极大地改善学习和培训的机会，以及访问网络信息。研讨会报告将建议研究和开发感知动画界面和虚拟人的具体步骤。

Perceptive Animated Interfaces represent a new generation of human computer interaction, in which people interact with machines much like people interact with each other in specific task domains. These interfaces incorporate virtual humans-lifelike three dimensional animated computer characters that exhibit expert intelligence and behaviors in specific task domains, such as learning and training. Virtual humans orient to the user, provide real time feedback as the user is speaking (e.g., head nods, smiles, puzzled looks), interpret the user's auditory and visual behaviors to infer his or her intentions and cognitive state, and communicate with the user sensitively and effectively to achieve the goals of the task through natural face-to-face dialogues. The goal of the Workshop on Perceptive Animated Interfaces and Virtual Humans is to bring together interested researchers from scientific disciplines to help conceptualize the challenges involved in developing perceptive animated interfaces incorporating virtual humans, to consider possible research agendas and the steps required to form a community that will work together to stimulate progress toward shared research goals. Participants include scientists from areas of human communication, human interface design, human language technology, computer vision, computer animation, cognitive science and other relevant fields of study. Workshop activities include assessing current theories and practice in relevant disciplines, defining research goals and objectives, evaluating system architectures, identifying task domains for which prototype systems can be developed as test beds for research, and identifying critical infrastructure necessary to conduct proposed work. The development of perceptive animated interfaces is expected to revolutionize human computer interaction by providing more natural and effective communication experiences, and to improve dramatically opportunities for learning and training, and access to networked information. The workshop report will recommend concrete steps toward research and development of perceptive animated interfaces and virtual humans.
