Next-Gen Augmented Reality Will Go Beyond Google Glass

March 12, 2013, By Sanjeev Ramachandran

Todd Humphreys is popular among TED fans for his videos that showed how absurd GPS systems can be and how we can tweak it to perfection.

But this time at SXSW, he’s gone far beyond Google Glass as the Augmented Reality (AR) discovery that could revolutionize the tech world. Todd and his students showed off what could be the next gen AR and it certainly threw us!

The key to Humphreys’ next gen AR is the fusion of two readily available technologies – carrier-phase differential GPS (CDGPS) and an inertial measurement unit (IMU). The IMU helps place and track objects in their local environment, and fusing that data with CDGPS will provide accurate details.


The result is a technique that eliminates the need to map the whole world in advance by essentially mapping just the local area on the fly (with an IMU and camera) and then placing that reference frame into a global context (via CDGPS).

Todd Humphreys is director of the University of Texas at Austin’s Radionavigation Laboratory where he works as an assistant professor in the Department of Aerospace Engineering and Engineering Mechanics.

His research into orbital mechanics has made him one of the world’s leading experts on GPS technology and the security concerns that arise from its ubiquitous use.  In 2008 he co-founded Coherent Navigation, a start-up dedicated to creating more secure GPS systems.
