(CNN) - It's seen as the next tech frontier. Technology you actually wear, rather than just carry around.
"I think we've moved from desktop to mobile to tablet, and now we're just going to be wearing our computers," Marvin Ammori with Silica Labs said.
Google glass developers like Washington's Silica Labs see a potential for apps in healthcare and law enforcement.
But in addition to creating buzz, wearable tech is also creating some privacy concerns.
A recent survey by cloud computing operator Rackspace found the majority of wearable tech users said it's enhanced their lives in some way. But among those hesitant to adopt it, 51 percent cited privacy as a barrier.
"Google Glass and wearable tech have a sort of always on feature. Whereas with smartphones if you wanted to take a picture or take a video you had to hold the device out in front of you in a somewhat obvious way," David Jacobs said.
Along with surveillance, the Electronic Privacy Information Center cites data collection and access to that data, stored in the cloud, as chief concerns.
In addition to certain design features, Google has also laid out rules for developers.
Among the rules - no facial recognition.
"We as developers try to follow those policies, and we follow the golden rule of technology, which is, try not to be creepy," Ammori said.
Like any new technology. Early adopters see users eventually getting used to it all.
"Once people have developed software for it that'll change our lives, I think we'll forget what life was like before we had these things," Ammori said.
