In some implementations, a mobile device can be configured with virtual motion fences that delineate domains of motion detectable by the mobile device. In some implementations, the mobile device can be configured to invoke an application or function when the mobile device enters or exits a motion domain (by crossing a motion fence). In some implementations, entering or exiting a motion domain can cause components of the mobile device to power on or off (or awaken or sleep) in an incremental manner. |
