a display device configured to output an image;
an image forming optical system configured to convey light corresponding to the image through a light transmission region such that a virtual image corresponding to the image appears on a ground surface in the light transmission region, the ground surface being in front of a vehicle; and
a controller configured to,
generate the image based on an eye-box such that a 2D graphic object and a 3D graphic object appear at the ground surface in the light transmission region,
the 2D graphic object corresponding to the ground surface and the 3D graphic object having a stereoscopic effect,
the eye-box being defined based on a viewing angle of a driver of the vehicle, the 3D graphic object corresponding to a 3D object projected onto the ground surface using a first conversion matrix, the first conversion matrix corresponding to a first view and a second view,
the first view being towards the ground surface, the second view being towards a 3D space above the ground surface, and the first view and the second view being based on the eye-box, and
