Researchers in the Microsoft lab of Jaron Lanier are experimenting with multi-person augmented reality, and the results of their work could help shape the way the technology is commercialized and used. Lanier was a pioneer of virtual and augmented, or mixed, reality in the 1980s.Microsoft is testing a commercial augmented reality product, called HoloLens. Lanier stresses that his work is separate from HoloLens and does not reflect how that product will develop. Still, multi-person mixed reality is a long-standing challenge for those interested in the technology. Beyond gaming, there is hope that virtual and augmented reality could prove useful for communications, collaboration, and for new ways of accessing and handling information.Lanier’s project is called Comradre (and pronounced “comradery”). A video produced by Lanier’s lab shows several projects developed by student interns in which more than one person interacts with the same virtual object or phenomena. These headsets were made using smartphones and laptop computers, and the tracking of a person’s head movements are performed using external sensors. And most of the footage was shot through one of the headsets.
