Abstract:
1. An image display apparatus, comprising: a body; a display unit configured to display a 3D screen corresponding to a 3D space and divided into a plurality of regions; an exciter having a plurality of vibration generators disposed on the body, each vibration generator overlapped with one of the plurality of regions of the 3D screen and each region of the plurality of regions overlapping with one of the plurality of vibration generators; and a controller configured to: display an event graphic image corresponding to a virtual event in the 3D space, on one region of the plurality of regions of the 3D screen; calculate a distance between a user object and a point of the virtual event in the 3D space; calculate an intensity of a vibration at the point; extract at least one material present in the 3D space between the point and the user object; change the intensity of the vibration at the point based on type, property or size of the material; and control one vibration generator of the exciter to output vibration based on the changed intensity of the vibration, wherein the one vibration generator outputting the vibration is overlapped with the one region of the plurality of regions of the 3D screen.
