ITR: Beyond the Talking Head and Animated Icon: Behaviorally Situated Avatars for Tutoring

一对一辅导是教与学的重要组成部分。本计画探讨技术，以部署一个随时随地的导师随时随地的学生系统，允许导师通过动画化身提供指导。利用心理语言学信息，该系统将在LCD平板电脑上执行的时间定位指向和交流手势与语音一起转换成由化身导师执行的行为正确的空间定位3D手势流。 一个摄像头跟踪学生，促进化身的社会意识行为。 该系统利用学生的能力，使用身体运动线索的体现化身，以引导她的注意力投影图形，作为工件的指令的适当位置。 该技术将有可能促进一个辅导计划，在该计划中，学生可以连接到一个导师池，以获得各种主题的帮助。 该方法基本上实现了在交互的两端辅导“电话听筒”。 导师可以分布在多个地点在他们方便，并采取呼吁，因为他们是需要的。广泛提供这种辅导将有助于实现普遍提供教育机会的愿景。 该项目将研究必要的人工智能和交互技术，并评估这种辅导方法的有效性。

Behaviorally Situated Avatars for Tutoring: Beyond the Talking Head and Animated IconAbstractOne-on-one tutoring is a critical component of teaching and learning. This project investigates technology to deploy an anywhere-tutor anywhere-student system that permits a tutor to provide instruction via an animated avatar. Exploiting psycholinguistic information, the system translates time-situated pointing and communicative gestures performed on a LCD tablet in conjunction with speech into a stream of behaviorally correct, spatially situated 3D gestures performed by the avatar tutor. A camera tracks the student, facilitating socially aware behavior by the avatar. The system exploits the student's ability to use body motion cues in the embodied avatar to direct her attention to appropriate locations of projected graphics that serve as artifacts of instruction. The technology will potentially facilitate a tutoring program in which students may connect to a pool of tutors for help with a variety of topics. The approach essentially implements tutoring 'telephone handsets' at both ends of the interaction. Tutors may be distributed across multiple sites at their convenience and take calls as they are needed. Widespread access to such tutoring will facilitate the vision of universally available educational opportunities. The project will investigate the necessary artificial intelligence and interaction technologies and evaluate the efficacy of this tutoring methodology.
