Abstract

In an image display apparatus for outputting a vibration with a sense of realism and an realistic sense and a method for adjusting an intensity of vibration for implementing a vibration with sense of realism and an realistic sense, a user of the image display apparatus can directly recognize (experience) a situation happened on a space formed by a screen by virtue of the vibration with the sense or presence and the realistic sense, output in association with an effect of a displayed image, and also can feel more the sense of realism and the realistic sense from the situation in the game or a virtual reality.
