Below is a four minute video showing an example of some of the innovative research and technology under development.
D4AR - 4 dimensional augmented reality - Modeling from RAAMAC Lab on Vimeo.
This project is led by Mani Golparvar-Fard at Virginia Tech, Feniosky Pena-Mora at Columbia University, and Silvio Savarese at the University of Michigan. More information available here.
Charles Woodward from Finland's VTT also presented very compelling AR research and technology demos at the event. More information on his research here. A 10-page PDF with more info here.
Look for more AEC-related augmented reality innovation at the upcoming ISMAR conference in Basel, Switzerland October 26-29th and at the 11th International Conference on Construction Applications of Virtual Reality (CONVR), in Weimar, Germany on November 3-4th.
