Patent ID: 7978180

Claim:
An apparatus for providing haptics of an image displayed through an image unit, comprising: a haptics numerically calculating unit dividing the image to be displayed into a plurality of regions where each region includes a respective designated number of pixels, the respective designated number being determined in consideration of a resolution of haptics to be provided to a user and a size of a portion of the image to be touched by the user, and calculating haptic information of each region, where at least two of the plurality of regions have different sizes of haptics; a touch unit checking whether a user has touched a portion of the divided image, and searching for a position of the portion based on the checking; and a magnetic force changing unit selecting the calculated haptic information corresponding to the position searched by the touch unit, changing magnetic forces in response to the calculated haptic information corresponding to the position and expressing the changed magnetic forces through the image unit, wherein the magnetic force changing unit comprises: a lower magnetic force unit, and an upper magnetic force unit that includes a fewer number of electromagnetic cells than the lower magnetic force unit and the fewer number of electromagnetic cells are movable to the touched position with respect to the lower magnetic force unit to change the magnetic forces, wherein haptics of the portion are provided through a change of the expressed magnetic forces.
