Google has revealed details of its research into augmented reality glasses.

It posted a brief introduction to Project Glass, photos and a concept video at its Google+ social network.

The images show a minimalist design with a microphone and partly-transparent video screen that places information over the view from the users’ right eye.

The product’s developers said they wanted feedback on the idea.

They did not give any indication about when the device might go on sale or what it would cost.

“A group of us… started Project Glass to build this kind of technology, one that helps you explore and share your world, putting you back in the moment,” said a statement from Google X – the firm’s experimental lab.

There is concern that children are no longer being equipped with the necessary computer development skills needed to fuel a 21st century tech-based economy.

The UK Government is looking to industry to inspire school children into making technology of the future.

Click’s Mark Cieslak looks at why this could mean that the way computer science was taught in schools in the 1980s could be making a comeback.

More than half a million Apple computers have been infected with the Flashback Trojan, according to a Russian anti-virus firm.

Its report claims that about 600,000 Macs have installed the malware – potentially allowing them to be hijacked and used as a “botnet”.

The firm, Dr Web, says that more than half that number are based in the US.

Apple has released a security update, but users who have not installed the patch remain exposed.

Flashback was first detected last September when anti-virus researchers flagged up software masquerading itself as a Flash Player update. Once downloaded it deactivated some of the computer’s security software.

Later versions of the malware exploited weaknesses in the Java programming language to allow the code to be installed from bogus sites without the user’s permission.
