1. A method comprising:

  • establishing a low-power wireless connection between a wearable device and a client device;

    receiving, at low-power wireless circuitry of the wearable device, a display communication comprising instructions to display content data including visual direction information indicating a path of direction and a turn on a display of the wearable device;

    processing, by a low-power processor coupled to the low-power wireless circuitry, the display communication;

    powering, in response to the processing of the display communication, a high-speed processor;

    accessing, by the high-speed processor, the content data;

    accessing, by the wearable device, location data from a global positioning system (GPS) receiver;

    determining, using the high-speed processor and the location data, that a physical location of a user is approaching the path of direction of the visual direction information;

    displaying the visual direction information in response to the determining that the physical location of the user is approaching the path of direction;

    determining, using the positioning system, whether the turn of the visual direction information displayed on the wearable device has been made;

    determining, by the high-speed processor, a first period of time for display of the content data based on whether the turn of the visual direction information has been made;

    powering on the display and displaying, using the display, the content data for the first period of time;

    automatically turning off the display following display of the content data for the first period of time; and

    automatically turning off the high-speed processor following display of the content data for the first period of time.
