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;
an eye gaze detection unit configured to detect a third route along which a user'"'"'s eye gaze moves;
a display unit configured to display visual information; and
a controller configured to;
control a focus of the camera unit based on a route of a reference object and the detected third route; and
display the visual information between an eye of the user and the reference object,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,if the detected first route of the first moving object is substantially identical with the detected third route, set the first moving object as the reference object,if the detected second route of the second moving object is substantially identical with the detected third route, set the second moving object as the reference object, andset the focus of the camera unit on the set reference object.

Abstract
A control method of a head mounted display (HMD) is disclosed. The control method 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 a user'"'"'s eye gaze moves, setting the first moving object as a reference object if the detected first route identical with the detected third route, setting the second moving object as the reference object if the detected second route identical with the detected third route, and setting a focus of the camera unit on the set reference object based on a route of the set reference object and the detected third route.

19. A control method of an 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; detecting, via an eye gaze detection unit, a third route along which a 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; setting, via the controller, the first moving object as the reference object if the detected first route of the first moving object 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 of the second moving object is substantially identical with the detected third route; setting, via the controller, a focus of the camera unit on the set reference object based on a route of the set reference object and the detected third route, and displaying on a display unit, via the controller, visual information between an eye of the user and the reference object, wherein the plurality of real moving objects are not images displayed by the display unit.
