    • Computer-readable media, computerized methods, and computer systems for intuitively invoking a presentation action (e.g., rendering a menu) by applying a drag-operation at a top-level control button rendered at a touchscreen display are provided. Initially, aspects of a user-initiated input applied at the top-level control button are detected. These aspects may include an actuation location and a distance of a drag-movement therefrom. If a distance of the drag-movement at the touchscreen display is greater than a threshold distance in a particular radial direction from the actuation location, the user-initiated input is considered a drag-operation. Typically, a set of trigger boundaries are constructed based on system metrics to assist in disambiguating the drag-operation from a tap-type operation. If a drag-operation is identified, the presentation action is invoked; otherwise, a principle action associated with the top-level control button (e.g., manipulating content of an application) may be invoked.
    • 提供了计算机可读介质,计算机化方法和用于通过在触摸屏显示器处呈现的顶级控制按钮上应用拖动操作直观地调用呈现动作(例如呈现菜单)的计算机系统。 最初,检测在顶级控制按钮上应用的用户发起的输入的方面。 这些方面可以包括致动位置和从其移动的距离。 如果触摸屏显示器上的拖动移动的距离大于在距离致动位置的特定径向方向上的阈值距离,则用户启动的输入被认为是拖动操作。 通常,基于系统度量来构造一组触发边界,以帮助消除拖拽操作与抽头式操作的歧义。 如果确定了拖动操作,则调用演示动作; 否则,可以调用与顶级控制按钮相关联的主要动作(例如,操纵应用的内容)。
