Google Glass is a wearable high-tech pair of spectacles that connects to the internet. It can display information, run apps, take pictures and video and respond to voice commands. With companies currently betting big on smartwatches, Google has gone one step further and believes that soon we'll all be walking around wearing super-intelligent glasses.
We're keeping track of all the latest Google Glass updates including the latest Google Glass news, rumours, price details and release date information. This piece will be regularly updated with the latest news appearing at the top.
GOOGLE GLASS RELEASE DATE
Google Glass is already available on general sale in the US, but it still costs $1,500 (£890). Google said it would continue to sell Glass until stocks ran out as part of its Explorer Programme. The company explained that this version of Glass wasn't the final retail version and that the technology was still in its extended testing period. Glass remains unavailable to people living outside the USA.
Google has previously said that Google Glass will launch "later in 2014". No more specific details than that are available. How widespread that launch will be is up for debate.
The Google Glass Explorer scheme has remained US-only. In its terms Google says you need to be a US resident with a US shipping address and aged 18 or older. It is therefore possible that the full launch of Glass later this year will be US only. There's certainly precedent on Google's part, the company has a history of launching certain services and products in the US first.
GOOGLE GLASS PRICE: HOW MUCH WILL GLASS COST?
At the moment Google Glass is only available as part of Google's Explorer program for a whopping $1,500 (£888). Google has admitted that the full-release version will cost significantly less. It has been speculated that the company will sell Glass for the same as a mid-range smartphone, with a $600 (£355) mooted.
Anyone eager to get their hands on Google Glass early had their chance on 15 April with Google putting it on sale for one day only. Glass ended up selling more than expected, with Google pulling the plug a tad early, but not before lots of keen punters had snapped one up.
As with the Google Glass Explorer program, everyone who purchased one on 15 April paid $1,500. The one-day sale was once again US-only, with Google saying it "wasn't ready" to bring Glass to other countries yet.
In early May a teardown of Google Glass revealed how much it costs Google to make one unit - $79.78 (£47). According to teardown.com the most expensive component in Google Glass is the processor at $13.96 (£8.27) with connectivity parts and non-electric elements also costing around £8. The teardown was conducted on the 16GB model of Google Glass.
Google has said the figure is "absolutely wrong", adding that that Glass costs "significantly more" to produce. In the past Google has said that the consumer version of Google Glass will cost less than the $1500 'explorer' version that is currently being tested.
According to the teardown the battery costs Google just $1.14, while the camera is $5.66. Assembly and testing on each Google Glass sets Google back $2.15.
GOOGLE GLASS TECHNICAL SPECS
Google Glass has just been updated to Android 4.4.2 KitKat. The update has improved battery life and added lots of new features. However Google has removed video calling from Glass, claiming that less than 10 per cent of people were using it.
On the inside Google Glass has 1GB of memory, 16GB of Flash storage and a 5MP camera that can record video at 720p. It also has Wi-Fi, Bluetooth, a micro USB port, GPS, accelerometer, compass and gyroscope. The processor has been reported as a Texas Instruments OMAP 4430, although the clock speed isn't clear.
The 640 x 360 display might seem awful but as it is located to close to your eye it is actually the equivalent of watching a 25in screen from 2.4m away. As a result, it looks a lot higher quality than the resolution suggests.
GOOGLE GLASS FEATURES: WHAT APPS RUN ON GLASS?
Google Glass apps, also known as Glassware, is what will make the specs a hit or a massive failure. Google has done a lot of work on the customised Android operating system. The 'OK Glass' launcher lets you search Google, take a picture, get directions, send messages and emails, make calls, start a Google Hangout and access Google Now for appointments, flight details and bookings.
Scores of third-party apps are also in the works. The New York Times, Twitter, Facebook, Evernote, CNN and dozens of other websites and services have already developed apps for Glass, with more developers popping up all the time.In May it was reported that Google Wallet will soon be launched on Glass, letting people send money using their voice. TechCrunch reports that people will be able to make payments through Google Wallet on Glass by saying "send money". While it will initially only be available to people on Google's corporate network, the Wallet 'glassware' will be released more widely soon.Google Wallet for Glass can be used to quickly send money. Suggested uses include owing a friend or family member money or splitting a bill at a restaurant. In order to transfer money users will need to say "send money" and then swipe through the Wallet interface to select the appropriate options. Google takes a cut of all payments made through Wallet either 30c (18p) or 2.9 per cent, whichever is higher.

DESIGNER VERSIONS OF GOOGLE GLASS
Google has teamed-up with Luxottica, the Italian design firm behind Ray-Ban, Oakley and Vogue-Eyewear. The deal, announced in March, will see Luxottica offer its design expertise to try and make Google Glass appeal to people outside its 'geeky' niche.Google has already revealed prescription frame versions of Glass, with a range of colours and styles available. Google launched four new styles - Bold, Split, Curve and Thin. Two new tinted shade syles, Classic and Edge, were also been added to the range. It is very likely that Google will sell Glass in a variety of looks, from designer shades to more basic frames and a 'standard' Glass model.
GOOGLE GLASS PRIVACY AND SAFETY CONCERNS
Google Glass has already had a major setback in the UK – it is likely to be banned on roads. The Department of Transport has said that it is aware of Glass and considers it unsafe:We are aware of the impending rollout of Google Glass and are in discussion with the Police to ensure that individuals do not use this technology while driving," the DfT said in a statement.Google has attempted to calm fears that Glass will cause a massive invasion of privacy by issuing its 'top 10 Google Glass myths'. In a post on Google+, the company said that glass wasn't a distraction and couldn't record everything.

Google said Glass isn't capable of always recording video as its battery would only last 45 minutes and said that people wouldn't want to record everything they do anyway.Google also said that Glass wasn't just for geeks and was used by people from "all walks of life", including "parents, firefighters, zookeepers, brewmasters, film students, reporters, and doctors". The company said that Glass allowed people to get on with their lives without being "distracted by technology".Google also pointed out that Glass is a terrible spying device because it is on people's faces and has flashy lights. The company also explained that Glass isn't capable of facial recognition.1\o651
