    • A method simplified drag and drop operations of display icons. This method calculates a projected path for an icon based on the past movement of the icon. The method highlights the “best fit” target icon as the mouse pointer moves across the screen. As the mouse pointer moves, or changes direction, the “best fit” target icon can change, with the current best-fit icon being highlighted. In addition to highlighting the target icon, a line or arrow from the mouse pointer to the target icon is maintained. The line presents the predicted path in a very noticeable, visual way. As the best-fit target icon changes, the line is re-drawn to point to the current best-fit icon. Regardless of how the target icon is visually indicated, releasing the mouse button will cause the drop operation to be completed “into” target. Completion of the drop could be instantaneous, or could be rendered with animation of some sort to indicate moving from the source to the target.
    • 一种方法简化了显示图标的拖放操作。 该方法基于图标的过去运动来计算图标的投影路径。 该方法突出显示“最佳拟合”目标图标,鼠标指针移动到屏幕上。 当鼠标指针移动或改变方向时,“最佳拟合”目标图标可以改变,当前最佳拟合图标被突出显示。 除了突出显示目标图标之外,维护从鼠标指针到目标图标的线或箭头。 该线以非常明显的视觉方式呈现预测的路径。 当最佳拟合目标图标更改时,该线条将被重新绘制,以指向当前最佳拟合图标。 无论目标图标如何被视觉指示,释放鼠标按钮将使得drop操作完成“into”目标。 完成下降可能是瞬时的,或者可以使用某种动画来表示从源到目标的移动。
