摘要
目前存在的CAD系统由于交互方式不自然,交互效率低,缺乏对概念设计中模糊信息的支持,中断了设计信息流,导致概念设计与后续设计过程断裂,增加了设计周期和工作量。针对当前CAD系统的不足,提出对于支持概念设计的笔式CAD系统的研究,并探讨实现这样一个系统的问题及解决。其目的在于通过高效地使用当前的手势识别和草图识别技术,支持用户从开始的模糊意图所产生的随手笔画,到最后进行精确定位和绘制,使概念设计与详细设计过程整合,减少工作量和缩短设计周期。
Most present CAD systems lack of mechanics to support the input of vague information. Unnatural human - computer interfaces lead to low interacting efficiency, and the break up of conceptual design and consequent design process bring about increased work load and prolonged design cycle. To resolve these shortages of present CAD systems, studied a pen - input CAD system which is to support conceptual design. Make use of present gesture recognition techniques and sketch recognition techniques efficiently in order to support users starting from inputting vague sketch to draw detailed drawings.
