HEAD MOUNTED DISPLAY PROVIDING EYE GAZE CALIBRATION AND CONTROL METHOD THEREOF
First Claim
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 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;
if the detected first route is substantially identical with the detected third route, set the first moving object as the reference object, andif 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.

-
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.
