An Object Expression System using Depth-maps

In existing Augmented Reality (AR), data gloves or markers are used for smooth interactions between objects and backgrounds. This results in inconvenience in use and reduced immersiveness. To reinforce immersiveness in AR, added input devices should be removed. To this end, spatial coordinates should be accurately perceived even when a marker has been attached. In this paper, an object expression system was proposed that uses depth-maps for interactions without any additional input devices in order to improve immersiveness. Immersiveness was improved by projecting obtained images on two-dimensional (2D) spaces, extracting vanishing lines, calculating the virtual spatial coordinates of the projected images, and varying the sizes of the inserted objects in accordance with the sizes of the areas of virtual coordinates, based on the images projected on the 2D coordinates. By using this system, the use of three-dimensional (3D) modelers could be excluded when 3D objects were created, thus, the efficiency of object creation could be improved.
