【摘要】：针对现有虚拟装配系统中交互是以设备为中心的显式交互,不能有效地感知用户操作意图,用户认知负担和操作负担较高的问题,为了提高虚拟装配系统的智能性,将隐式人机交互引入虚拟装配系统,提出一种基于场景任务的用户意图感知算法.首先建立场景知识模型和用户知识模型,并分别构建显式交互知识库和隐式交互知识库;然后利用专家系统推理用户显式操作意图和隐式操作意图,实现人手向目标位置平移时场景主动拉近和抓放场景物体时物体主动旋转2种情景下的人机相向互动.实验结果表明,该算法实现了人机协同交互,降低了用户的操作负担和认知负担.
[Abstract]:In order to improve the intelligence of virtual assembly system, interaction is a kind of explicit interaction centered on equipment, which can not effectively perceive user's operation intention, user's cognitive burden and operation burden, in order to improve the intelligence of virtual assembly system. Implicit human-computer interaction is introduced into virtual assembly system, and a user intention perception algorithm based on scene task is proposed. Firstly, the scene knowledge model and user knowledge model are established, and the explicit interactive knowledge base and implicit interactive knowledge base are constructed, and then the explicit and implicit operation intention of user is deduced by expert system. The man-machine interaction is realized in the two situations when the human hand moves to the target position and the scene is actively drawn close and the object is rotated actively when the scene object is grasped. The experimental results show that the algorithm realizes man-machine cooperative interaction and reduces the user's burden of operation and cognition.
