Google has recently released version two of their new wearable technology, Glass. And the product, which resembles a pair of eyeglasses, has been kicking up a lot of conversation about the benefits and concerns.

Glass is not currently on sale to consumers, but Jason Katterhenry, Arizona Public Media's technology contributor, said that Google released around 1,500 pairs to selected beta testers.

Brian Klug, senior editor for was one of the few who received a pair of the first version of Glass.

"At present, the functionality is kind of limited, but it's sort of at a high level companion device for your phone," Klug said.

Even though Glass is not yet available to the public, researches have already been looking for ways to create a better version.

Dr. Hong Hua, associate professor the UA's College of Optical Science is working on technology that will track the eye movement of the user and translate it into commands.

"For instance, one potential application of the technology is to be able to use it for patients with Parkinson's disease," she said.

Privacy Concerns

The product has also raised privacy concerns. For that reason, Glass has been banned from places, such as casinos, strip clubs and bars.

Also, many concerns have emerged around the usage of Glass while driving or the ability to discreetly capture photos and videos.

"I think that we will probably have to adapt, a little bit, our expectations in the same way we would expect Google to alter the way that Google Glass works as well," said Derek Bambauer, who is a UA law professor.
