1. A head-mounted computing device for positioning a target indicator displayed via a display system, the head-mounted computing device operatively connected to the display system, the head-mounted computing device comprising:

  • a gaze tracking system for generating gaze tracking data having a coarse accuracy from a user wearing the head-mounted computing device;

    a head tracking system for generating head pose data from the user, wherein the head pose data has a fine accuracy that is greater than the coarse accuracy of the gaze tracking data; and

    a positioning module executed by a processor of the head-mounted computing device, the positioning module configured to;

    using the gaze tracking data, determine an approximate user gaze region within a display region generated by the display system;

    control the display system to display the target indicator at an initial location within the approximate user gaze region;

    receive a reposition input from the user;

    in response to receiving the reposition input, use subsequently received head pose data to calculate an adjusted location for the target indicator in the display region; and

    control the display system to display the target indicator at the adjusted location in the display region.
