Modern Approaches to Augmented Reality

Abstract

This tutorial provides a survey of modern techniques for augmented reality (AR) systems. Novel approaches have taken AR beyond traditional eye-worn or hand-held displays, enabling new application areas. We discuss conventional AR displays and present alternative augmented reality approaches that are overcoming some of their limitations. These practical alternatives are spatially augmented displays that exploit large optical elements, video-projectors, holograms, and tracking technologies. Due to the fall in the cost of these devices and graphics resources, there has been a considerable interest in exploiting such augmented reality systems in universities, labs, museums and in the art community.
