Asynchronous interaction handoff to system at arbitrary time

User input that is part of a user interaction with a computing device is received by a system module. The system module notifies the application of the user input, and the application determines whether the application is to handle the user interaction or the whether the operating system is to handle the user interaction. For user interactions that the operating system is to handle, the application notifies the operating system to handle the user interaction. For the duration of the user interaction, the operating system then determines what changes to make to a display of data based on the user interaction and need not (and typically does not) notify the application of the user input. Thus, the application hands off the user interaction to the operating system. 作为与计算设备的用户交互的部分的用户输入由系统模块接收。系统模块向应用通知用户输入，并且应用确定是应用将处理用户交互还是操作系统将处理用户交互。对于操作系统将处理的用户交互，应用通知操作系统处理用户交互。在用户交互的持续时间内，操作系统然后基于用户交互确定对数据的显示做出什么改变，并且不需要(并且通常不)向应用通知用户输入。因此，应用将用户交互移交到操作系统。
