Proximity-based management of computing devices

Techniques are disclosed for enabling a user computing device to manage a controlled device only when the user computing device is physically proximate to the controlled device. The controlled device repeatedly provides a rotation code that changes at a selected time, and the user computing device sends back the last received or captured code to the controlled device. A user computing device is capable of managing a controlled device when a latest code sent by the user computing device matches one or more codes recently provided by the controlled device. Additionally or alternatively, a user computing device can manage a controlled device when the user and the controlled device are connected to the same access point. A technique for enabling a user computing device to share, mirror, or project a screen on the user computing device onto a display of a controlled device is also disclosed. 公开了用于使得用户计算设备能够仅在用户计算机设备物理地接近于受控设备时才能够管理受控设备的技术。所述受控设备重复地提供在选定的时间改变的旋转代码，并且用户计算设备将最后接收或捕获的代码发送回到所述受控设备。当由用户计算设备发送的最新代码与由受控设备
