A new type of wearable technology could redefine the AR experience.

Andrew Maimone, a University of North Carolina at Chapel Hill PhD student, has developed augmented reality (AR) glasses that would allow users to digitally interact with the real world, except Maimone’s glasses are sleek, compact, and light and are realistically wearable and less of a “gimmick” in comparison to conventional AR devices.

The new AR glasses provide a wide field of view.

Maimone commented that while it is possible to utilize a tablet or a even a smartphone to call up a virtual place and character and superimpose it on the real world via a small mobile screen, this experience is not “very compelling” because the experience does not occur through a person’s vision. The smartphone or tablet only allows the user to look at the virtual place through a small window.

On the other hand, traditional augmented reality glasses are bulky due to several components that are required to make the technology work, such as lenses, waveguides, reflectors, beam splitters, and additional optics that relay a digital image to the eye and place it at a distance where it can be focused on by the eye. Unfortunately, all of the bulk this tech creates can limit a person’s field of view.

Maimone’s device is called a Pinlight Display and he has been working on this device in collaboration with three researchers from the University of North Carolina and two from Nvidia Research. The Pinlight Display does not rely on standard optical components. Instead, it utilizes an array of “pinlights”, which are essentially bright dots.

Maimone explains that “A transparent display panel is placed between the pinlights and the eye to modulate the light and form the perceived image.” He added that “Since the light rays that hit each display pixel come from the same direction, they appear in focus without the use of lenses.”

Early prototypes of the augmented reality Pinlight Displays have demonstrated 100 degree fields of view.

Currently, the best commercial augmented reality glasses only offer a field of view of up to 40 degrees, while Maimone’s glasses have demonstrated fields of view of 100 degrees or higher. While this is no doubt impressive, the present prototype is not without its problems. It currently has image quality and low resolution issues. Maimone says that the next step is to work on improving these elements. He firmly believes, however, that with the proper engineering and research, the technology could be made into something realistic for use in everyday life.

Microsoft takes a big step toward the wearable glasses market.

Recently, the computer software and electronics company acquired a patent for object-recognizing augmented reality glasses from Osterhout Design Group, a deal worth $150 million.

The smart glasses equipped with this technology could result in people interacting with their environment in a whole new way.

More specifically, the patent for which Microsoft filed is an application called “Wearable Behavior-based Vision System”. The wearable device that could result from this technology may be smart glasses that look like large sunglasses, which could enhance how the wearer interacts with his or her environment.

For instance, if the wearer was crossing the street and a vehicle happened to be approaching at a fast speed, the glasses would warn the wearer if the vehicle was perceived as a threat. In addition to this function, allegedly, the smart glasses could combine the real world with the virtual world. Thus, if the wearer were playing a game using the glasses, for example, and he or she were walking around their home, the glasses will incorporate objects from the real world (ex. furniture) with objects from the game (virtual world).

Rumors about Microsoft developing augmented reality glasses are nothing new.

Since November 2012, there have been rumors circulating about Microsoft working on some form of wearable tech involving glasses. However, by securing this patent, it does seem that the company is serious about entering the wearables space.

On the other hand, simply because a company files for a patent, this does not necessarily mean it will use the technology as has been rumored. Until Microsoft officially releases information regarding what it plans to do with the application, there still is no solid evidence to back the old rumors. After all, it is quite possible that the massive corporation may only be building a prototype device that they have no intention of releasing to the market or at least not for several years down the road.

That being said, if it turns out that Microsoft does create object-recognizing augmented reality glasses, it would produce a smart glass device equipped with unique features that Google Glass would lack.
