| 摘要: |
| 概念设计过程使用了多种图表来表示设计概念以及构建功能结构.将手绘草图作为设计者之间的一种通信语言引入到异地同步协同概念设计过程,提出了基于手绘草图的协同图表绘制多agent 系统,包含草图交互、草图识别、通信、协调等多个agent.讨论了各agent 之间的通信机制以及主要agent 的实现策略,包括草图识别以及语义一致性维护策略.将系统应用到协同流程图绘制领域,运行结果表明,该工具能够改善人机交互模式,促进多用户之间的交流和协作. |

| Abstract: |
| Diagrams are used for representing design concepts and constructing function structure in the stage of conceptual design. This paper considers sketches as the language of communication in cooperative conceptual design and presents a tool that enables distributed participants to cooperatively construct diagrams in the form of freehand sketches. The tool is designed and implemented as a multi-agent system, which contains a set of agents to fulfill the requirements, including sketch-based interaction, sketch recognition, communication and coordination. The operating strategies of these agents are also addressed, including communication between agents, sketch recognition algorithm, and semantic consistency maintenance. The proposed approach is implemented in cooperative flowchart drawing. |
