摘要： An apparatus and method for animating editing changes on a display device is provided. The invention is designed to operate preferably with a graphical editing system that permits both handwritten and typewritten data entry. Both the primary changes made by the user and the contextual changes resulting from the primary changes are animated at a visually apparent rate in multiple steps to permit a user and other viewers of the display device to understand the effects of an editing change on surrounding objects. The number of steps in which the changes are animated depends on the number of changes which must be made and the operation performed.

摘要： 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.

摘要： 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.
摘要翻译：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。
