摘要： The present invention relates to a method and system for haptic interaction in augmented reality. More specifically, the present invention relates to a method and system for haptic interaction in augmented reality that can effectively remove noise from real images captured by an image capturing device and minimize discontinuity of force generated in the haptic interaction so as to stably and smoothly perform the haptic interaction in the augmented reality.The present invention provides an augmented reality system and a method for providing augmented reality therefor, the augmented reality system comprising: a marker detecting unit that receives images for a real environment including markers and detects the markers included in the images; a marker position extracting unit that extracts the positions of the detected markers; a noise removing unit that removes noise from positional information of the markers extracted from the marker position extracting unit; a visual rendering unit including a virtual object augmenting unit that augments virtual objects corresponding to the markers and outputs them to the positions of the markers; a motion estimating unit that estimates the motion of the markers over a time step so as to perform the haptic rendering on the basis of the positional information of the markers transferred from the noise removing unit; a collision detecting unit that detects whether the virtual objects corresponding to the positions of the markers estimated by the motion estimating unit collide with end points of the haptic device; and a haptic rendering unit including reaction force calculating unit that calculates reaction force to be provided through the haptic device according to a determination of the collision detecting unit.
