METHOD AND SYSTEM FOR HAPTIC INTERACTION IN AUGMENTED REALITY
First Claim
1. An augmented reality system including haptic interaction, 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.
