现有的草图系统重在设计对象外形的表达,忽略了隐含在设计过程中用户思维活动的信息;另一方面,目前笔的交互方式尚不能自然、流畅地表达用户设计意图.通过分析草图界面信息对象和交互过程的特点,提出面向构思设计的应用系统框架ISF,以满足设计意图原型的快速生成;同时结合交互的任务、环境和用户偏好等上下文信息,建立从物理设备到逻辑工具映射的交互模型,旨在为此类系统的交互设计提供一定指导的方法.最后给出面向轻纺行业服装设计的应用实例——草图图板系统.应用结果表明,ISF能够为此类草图应用系统的设计给予一定的指导,满足自然、流畅的交互设计要求.
Most sketch-based systems emphasize on shape description of design intention, but the implicit information related to users' thinking is not fully taken into account during the design. On the other hand, current interaction modes of the pen in the sketch systems can hardly meet the requirements for natural and flexible expression of design intentions. Based on the analysis on the features of domain object and interaction process, an intelligent sketch-based framework for design capture (ISF) is proposed so as to create design prototype quickly. By accounting for the context of task, environment as well as user preference, we set up an interactive model to conduct the mapping from physical device to logical tools. Our prototype system demonstrates that ISF can provide guidance to sketch-based application design, and support natural and flexible user interaction.
