Abstract
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 for the stable and smooth haptic interaction in the augmented reality. The augmented reality system comprising: a marker detecting unit that detects a markers in 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; a visual rendering unit that augments virtual objects; a motion estimating unit that estimates the motion of the markers over a time; a collision detecting unit that detects collision between the virtual objects and an end point of the haptic device; and a haptic rendering unit that calculates reaction force to be provided through the haptic device.
