| 摘 要： | 以用户为中心的思想,引入笔交互风格,运用Fonseca和Jorge提出的模糊逻辑识别算法,采用了中科院软件所的笔式应用开发平台PenUI作为底层支撑,设计并实现了一个能识别基本几何图形和简单手势的交互式系统.所采用的识别算法是一种识别多笔画几何草图简单方法.它利用图形的暂时邻接关系和全局几何特征来识别一些简单的几何图形,其中有实线和虚线两种.

| Abstract: | According to the user-centred design notion,using recognition algorithm of fuzzy logic proposed by Fonseca and Jorge,in this paper it introduces the design and the realization of an interaction system which can recognize basic geometric figures and simple gestures.The system adopts pen based application development platform PenUI from the Institute of Software,the Chinese Academy of Science as the bottom support.The recognition algorithm used is a simple approach to recognise multi-stoke geometric sketches.... |
