| 基于笔式手势的自然交互是支持概念设计创新的有效方式.提出了一种笔式手势的层次概念模型,结合基于约束的自由勾画和上下文感知技术描述了手势设计方式,进一步讨论了手势内部的约束建立和求解算法;基于手势应用的范式,给出了概念设计中特征手势建模的应用实例,通过与传统建模和交互方式的对比,验证了特征手势建模的方便性.给出一个自然、高效的方法,以基于手势的方式来完成概念设计构思过程,采用笔式交互快速自然地记录下设计思路,所实现的系统方便了用户的创新设计,改善了人机交互模式. |

| Abstract: |
| Natural interaction based on pen gesture is efficient for innovation in conceptual design. This paper presents a hierarchy concept model for pen gesture design based on the interactive informal constraint sketch and context-awareness. Furthermore, it discusses the constraint foundation and solution. Feature gesture as an instance of gesture applications in conceptual design is given. Compared with the traditional modeling mode, the feature gesture is convenient. Gesture-based interaction gives a natural way to record the brain streaming quickly. This paper provides an efficient method for innovative design to improve human-computer interaction. |
