1. A computing device comprising:

  • a camera configured to capture image data indicative of a wearer field-of-view associated with a wearable computing device when worn; and

    a computing system configured to;

    determine optical flow from the image data;

    determine, based on the optical flow, that the wearable computing device is associated with movement of a vehicle;

    responsive to the determination that the wearable computing device is associated with movement of the vehicle;

    detect, from the image data, one or more objects in the wearer field-of-view that are indicative of an operator location in the vehicle;

    detect gaze data from a gaze tracking sensor that is indicative of focus on a side-view mirror, a rear-view mirror, a speedometer, or other operator-side instrument of the vehicle;

    determine, based at least in part on the detection of the one or more objects in the wearer field-of-view and the detection of gaze data indicative of focus on the side-view mirror, the rear-view mirror, the speedometer, or the other operator-side instrument of the vehicle, that the wearable computing device is positioned at the operator location in the vehicle;

    control a display to display information in a first mode, when the wearable computing device is associated with the operation of the vehicle; and

    control the display to display information in a second mode different from the first mode, when the wearable computing device is not associated with the operation of the vehicle.
