A live augmented reality tool for facilitating interpretation of 2D construction drawings

Abstract

Construction consists of a complex set of tasks in the 3D world based on instructions encoded in 2D drawings. Although the process is facilitated by the availability of 3D models displayed on digital tablets on construction sites, it is not always clear what is the exact 3D location of specific elements in 2D drawings. In this preliminary study, we propose a method based on a computer tablet and a head mounted augmentation system that enables the user to display a 3D element by clicking on its 2D representation on a construction drawing. Early results show that the method has potential, but highlights perception issues. We proposed and tested solutions to alleviate those issues.
