Battery, cloud apps and controls still a work-in-progress.
Google has further detailed Project Glass, with the company still deliberating on how the platform will be used.
Speaking in an interview with IEEE Spectrum, the head of the Google Glass project, Babak Parviz, said the search engine giant is continuing to experiment new ideas. He stressed that both the software and hardware development is progressing: "We constantly try out new ideas of how this platform can be used. We're also trying to make the platform more robust. This includes making the hardware more robust and the software more robust, so we can ship it to developers early this year."
Parviz continued on to discuss what the firm been working on since Project Glass' July debut. Currently, the device sports a touch pad for changing settings and Google is experimenting with voice commands.
The company is also working on integrating a phone call feature and increasing the battery life in order for it to last an entire day. He added that Google doesn't have any current plans to incorporate advertising on the device.
"This is a complicated thing. This is not a laptop or a smartphone. It's an entirely new platform. So how people interact with it and what people do with it is totally new territory. But we hope that when we ship this to developers, other people will also figure out what this very powerful platform is able to do."
Google Glass is expected to launch in 2014, with Google confirming that a select group of developers can purchase the $1,500 "Explorer" edition of the device during early 2013.
