Development of a sketch-input interface that distinguishes between gesture operations and figure-drawing operations

我们一直在不断地、全面地研究素描输入界面，以开发实用的素描绘图系统为目标，基于在素描时利用模糊信息的独特和一致的理念。在这项研究中，我们建立了一种算法，区分被识别为手势的绘画笔画和被识别为图形的绘画笔画。此外，利用该算法实现了区分手势操作和图形绘制操作的草图输入界面。

We have been continuously and comprehensively conducting research on sketch-input interface, aiming for practical sketch based drawing system, based on unique and consistent concept of making use of vagueness information while sketching. In this study, we established an algorithm that distinguishes between drawing strokes to be recognized as gestures and drawing strokes to be recognized as figures. Furthermore, utilizing the algorithm, we realized a sketch-input interface that distinguishes between gesture operations and figure-drawing operations.
