A head-mounted display (HMD), comprising:

• a head-mounted support;
• an optical system attached to the head-mounted support, wherein the optical system comprises a display having a central axis, wherein the display is configured to display images that are viewable from a viewing location;
• an infrared light source configured to illuminate the viewing location with infrared light such that infrared light is reflected from the viewing location as reflected infrared light;
• a camera configured to image the viewing location by collecting the reflected infrared light;
• a sensor configured to generate sensor data that relates to motion of the HMD;
• and
• a computer configured to determine a gaze axis based on one or more images of the viewing location obtained by the camera, control the display to display images based on the sensor data, determine a target object in the displayed images based on the gaze axis, and control the display to move the target object towards the central axis.

A non-transitory computer readable medium having stored therein instructions executable by a computing device to cause the computing device to perform functions, the functions comprising:

• controlling a display to display images, the display having a central axis;
• determining a gaze axis with respect to the central axis;
• determining a target object in the displayed images based on the gaze axis;
• and
• controlling the display to adjust the displayed images so as to move the target object towards the central axis, wherein controlling the display to adjust the displayed images comprises moving the target object at a tracking rate and adjusting the tracking rate based on a difference between the gaze axis and the central axis.

A method, comprising:

• displaying images on a display of a head-mounted display (HMD), wherein the displayed images are viewable at a viewing location and the display comprises a central axis;
• acquiring sensor data related to the motion of the HMD;
• controlling the display to display images based on the sensor data;
• determining a gaze axis based on one or more images of the viewing location obtained by a camera;
• determining a target object in the displayed images based on the gaze axis;
• and
• controlling the display to move the target object towards the central axis.
