    • A graphical editing system is provided which allows a user to draw number of commonly used gestures called primitive command gestures together in essentially one stroke. The primitive gestures are chosen to represent gestural syntax, analogous to a textual command syntax. The primitive gestures are concatenated. i.e., connected in a series of commands by a gestural operator called a break feature. Every input composite gesture is scanned to detect the break features. When found, the composite gesture is broken up into primitive gestures and each gesture is interpreted and executed in the order in which the individual gestures were drawn. The preferred break feature is sharp angle drawn between consecutive primitive gestures. In a composite gesture consisting of two primitive gestures, one being the selection gesture, the break feature is recognized as any departure from the selection gesture.
    • 提供了图形编辑系统,其允许用户在基本上一个笔画中一起绘制被称为原始指令手势的常用手势的数量。 选择原始手势来表示手势语法,类似于文本命令语法。 原始手势连接在一起。 即通过称为断点特征的手势操作器以一系列命令连接。 扫描每个输入复合手势以检测断点特征。 当发现时,复合手势被分解成原始手势,并且按照绘制个人手势的顺序来解释和执行每个手势。 优选的断裂特征是在连续原始手势之间绘制的锐角。 在由两个原始手势组成的复合手势中,一个是选择手势,断开特征被识别为与选择手势的任何偏离。

    • In a computer controlled display system capable of supporting free form graphical input, techniques for maintaining the topology of a node-link structure when nodes are moved. When a node is moved, arbitrarily shaped links to other nodes will automatically be reshaped. The manner in which the link reshapes will depend on where a node is moved relative to the node to which it is linked. Various techniques for reshaping the node in order to retain the node-link structure topology are provided. A link may be reshaped by curve transformation or flipping the link shape about an axis. Curve transformation is a technique wherein the shape characteristics of a link are retained no matter where the node is moved. However, links that intersect, i.e. pass through, the nodes may arise from such reshaping. Various techniques for correcting link intersection situations and include flipping the attachment points of the links on the nodes, truncating and reattaching the link at the point where a link intersects a node or rerouting the link so that intersection is avoided.
    • 在能够支持自由形式图形输入的计算机控制的显示系统中,当移动节点时,用于维护节点链接结构的拓扑的技术。 当节点移动时,任意形状的链接到其他节点将自动重新整形。 链接重塑的方式取决于节点相对于其链接的节点的移动位置。 提供了用于重新形成节点以保持节点链路结构拓扑的各种技术。 链接可以通过曲线变换重新整形,或者围绕轴旋转链接形状。 曲线变换是一种技术,其中链节的形状特征被保留,而不管节点何处被移动。 然而,这些重新整形可能产生相交,即通过节点的链接。 用于校正链路交叉情况的各种技术,包括翻转节点上的链接的附接点,在链路与节点相交点或重新路由链路的位置处截断并重新连接链路,从而避免交集。

    • A system features a data input scheme in which the nature of the entered data is irrelevant until the requirement made to perform a function with respect to that data. It is only when it becomes necessary to perform a function with respect to the data that the determination of the nature of the data become important. The desired function, which may include editing, rearranging, moving, etc., then results in a determination of the nature of the data in order to enable implementation of that specific function. The nature of the data can be determined to be in the form of a list, table, or diagram. To this end, a screen oriented display processing system is provided for the entry of informational data including a display means, a data entry means for entering informational data on the display means, a gesture entering means for entering handwritten gestural data on the display, the gestural data representing a gesture associated with at least a portion of the informational data on the display, an assignment means responsive to the entry of the gesture for assigning a function representative of the gesture to the portion of the informational data, and an implementing means responsive to the assignment means for implementing the function on the said portion of the informational data.
    • 系统具有数据输入方案,其中输入的数据的性质不相关,直到执行关于该数据的功能的要求为止。 仅当需要执行关于数据性质的确定变得重要的数据的功能时才是。 可能包括编辑,重排,移动等的期望功能然后导致数据的性质的确定,以便能够实现该特定功能。 可以将数据的性质确定为列表,表格或图表的形式。 为此,提供一种面向屏幕的显示处理系统,用于输入信息数据,包括显示装置,用于在显示装置上输入信息数据的数据输入装置,用于在显示器上输入手写手势数据的手势输入装置, 表示与显示器上的信息数据的至少一部分相关联的手势的手势数据,响应于用于将表示手势的功能分配给信息数据的部分的手势输入的分配装置,以及响应于 到用于在信息数据的所述部分上实现功能的分配装置。
