A wearable computing device can detect device-raising gestures. For example, onboard motion sensors of the device can detect movement of the device in real time and infer information about the spatial orientation of the device. Based on analysis of signals from the motion sensors, the device can detect a raise gesture, which can be a motion pattern consistent with the user moving the device's display into his line of sight. In response to detecting a raise gesture, the device can activate its display and/or other components. Detection of a raise gesture can occur in stages, and activation of different components can occur at different stages. |

1. A method executed in a device, the method comprising:
establishing, in a first processor of the device that the device is in a focus state, wherein the focus state includes a user interface component of the device being in an active state; receiving, by the first processor, a sequence of motion-sensor data samples from a motion sensor of the device; detecting, by the first processor, a change in an orientation of the device based on the motion-sensor data samples; identifying, by the first processor, a loss-of-focus gesture based at least in part on the change in the orientation; and notifying, by the first processor, another component of the device when the loss-of-focus gesture is detected. |
