Google Glass is widely discussed, not only by the Augmented Reality community, to collect ideas how to design and use the next generation of personal displays. At the moment, those ideas, e.g. assisting surgeons with projecting 2D information into their view and teaching medical students with live video views from the surgeon’s perspective during surgery, might focus mainly on features of Google Glass that are currently available (or that have been released by Google). But displaying 3D objects as part of the real 3D world will be very likely the next step. The medical domain has always been an application area for Augmented Reality that goes beyond marketing products and services. In particular the idea of looking into the patient has pushed many researchers and nowadays also companies to develop new Augmented Reality systems to be applied to various clinical scenarios, e.g. breast tumor resection, biopsy, and ultrasound examination during pregnancy.
In addition to Google Glass, having most probably the biggest existing marketing budget and the biggest audience, there are many more comparable and maybe even better, commercially available Augmented Reality glasses and prototypes. In particular the method of augmenting the real world with virtual objects can make the difference when letting the wearers of such goggles immerse themselves into an Augmented Reality scene. One important aspect is of course binocularity. Jürgen Röder, a Senior Software Engineer at Siemens and founder of ActiveAntiGlare, has generated a nice list of currently available and presents monocular Augmented Reality glasses and binocular Augmented Reality glasses next to other types of virtual reality glasses (http://www.activeantiglare.com).
