摘要： An electronic device includes a touch-sensitive surface, for example a touch pad or touch screen. The user interacts with the touch-sensitive surface, producing touch interactions. Some of these touch interactions may be detected as indicative of a grasp for manipulating a physical tool (e.g., the grasp for holding a pen). When these touch interactions are encountered, a corresponding virtual tool is instantiated. The virtual tool controls an action on the electronic device that is similar to an action that can be performed by the physical tool. For example, the virtual pen can be used to draw on the display, whereas the physical pen draws on paper. A representation of the virtual tool is also displayed on a display for the electronic device, possibly providing additional affordances, at a location that corresponds to a location of the detected touch interaction.

摘要翻译： 电子设备包括触敏表面，例如触摸板或触摸屏。 用户与触敏表面交互，产生触摸交互。 这些触摸交互中的一些可以被检测为用于操纵物理工具的抓握（例如，用于握持笔的抓握）。 当遇到这些触摸交互时，相应的虚拟工具被实例化。 虚拟工具控制电子设备上的操作，类似于可由物理工具执行的操作。 例如，虚拟笔可以用于画在显示器上，而物理笔画在纸上。 在对应于检测到的触摸交互的位置的位置处，虚拟工具的表示也显示在用于电子设备的显示器上，可能提供额外的可用性。
