Abstract: Provided are an augmented reality device and a method of operating the same. The augmented reality device adjusts a depth value based on a gravity direction measured by an IMU sensor in order to obtain a depth map having a high accuracy without an additional hardware module. The augmented reality device obtains a depth map from an image obtained using the camera, obtains a normal vector of at least one pixel included in the depth map, modifies a direction of the normal vector of the at least one pixel, based on the gravity direction measured by the IMU sensor, and adjusts a depth value of the at least one pixel based on the modified direction of the normal vector.

Abstract: Provided is a display apparatus having a structure of fixing an optical sheet to allow the optical sheet to expand uniformly even when a display is rotated. The display apparatus includes a liquid crystal panel; a backlight unit arranged to supply light to the liquid crystal panel; an optical sheet provided between the liquid crystal panel and the backlight unit and having a hole formed therein; and a sheet fixer configured to fix the optical sheet, wherein the sheet fixer includes: an anti-deviation projection inserted in the hole of the optical sheet to restrict movement of the optical sheet in a first direction, and a supporting projection contacting the optical sheet to restrict movement of the optical sheet in a second direction opposite the first direction.
