Patent Images
1. A head mounted display (HMD) comprising:
- a camera unit configured to detect a first route of a first moving object and a second route of a second moving object in front of the HMD;
a display unit configured to display visual information;
an eye gaze detection unit configured to detect a third route along which an eye gaze of a user moves; and
a controller configured to perform an eye gaze calibration based on a route of a reference object and the detected third route,wherein the controller is further configured to;
select the reference object from a plurality of real moving objects including the first moving object and the second moving object, wherein the reference object is selected by comparing the third route of the eye gaze with each route of the plurality of real moving objects, wherein the plurality of real moving objects are not images displayed by the display unit of the head mounted display;
change a position of the displayed visual image according to the result of the eye gaze calibration;
if the detected first route is substantially identical with the detected third route, set the first moving object as the reference object; and
if the detected second route is substantially identical with the detected third route, set the second moving object as the reference object.

Abstract
A control method of a head mounted display (HMD) is disclosed. The control method of the HMD includes detecting a first route of a first moving object and a second route of a second moving object in front of the HMD, detecting a third route along which user'"'"'s eye gaze moves, setting the first moving object as a reference object if the detected first route is substantially identical with the detected third route, setting the second moving object as the reference object if the detected second route is substantially identical with the detected third route, and performing an eye gaze calibration based on a route of the set reference object and the detected third route.

20. A control method of a HMD comprising:
-
detecting, via a camera unit, a first route of a first moving object and a second route of a second moving object in front of the HMD; display visual information on a display unit; detecting, via an eye gaze detection unit, a third route along which user'"'"'s eye gaze moves; selecting, via a controller, a reference object from a plurality of real moving objects including the first moving object and the second moving object, wherein the reference object is selected by comparing the third route of the eye gaze with each route of the plurality of real moving objects, wherein the plurality of real moving objects are not images displayed by the display unit of the head mounted display; changing, via the controller, a position of the displayed visual information according to a result of the eye gaze calibration; setting, via the controller, the first moving object as the reference object if the detected first route is substantially identical with the detected third route; setting, via the controller, the second moving object as the reference object if the detected second route is substantially identical with the detected third route; and performing, via the controller, an eye gaze calibration based on a route of the set reference object and the detected third route.
