1. A method for determining near touch interaction by a user object, comprising the steps of: displaying on a display one or more objects; acquiring one or more images of the user object by one or more pairs of stereo cameras located adjacent to the display; dewarping the one or more acquired images; computing a disparity based upon the dewarped images; and identifying one or more target regions of the display adjacent to one or more corresponding portions of the disparity that may benefit from refinement, and displaying one or more screen tessellations therein using the light sources that illuminate the display; wherein the tessellations are interleaved with the actual data, allowing for the display of the structured light without the light being perceived by the user.
