Google glass: is it the future?

Google Glass is the name for a type of wearable computer created by the Google's Project Glass. These futuristic glasses provide augmented reality for users by visually connecting them to an Android-run heads up display that offers many of the features of an Android spmartphone and connects users to many of Google's key cloud features, such as maps, calendar, Gmail, Google+ and Google Places.

In April 2012, Project Glass launched a Google+ page and revealed that Google researchers were testing the technology and hoped to have it on the market in the near future. Google expects the technology to cost about as a much as a smartphone.

Google Glass provide an experience known as augmented reality, where images are superimposed over what the user sees in real life. With Google Glass, these images are generally icons that provide directions, alert users to messages from contacts or give weather updates.

Although this technology's potential has been praised as a futuristic way to deliver hands-free computing, critics have pointed out its ability to distract walkers or drivers and questioned its utility for those who already wear corrective eyeglasses.

Google glasses are sometimes called Google goggles, although is is inaccurate because Google Goggles is actually a separate Google project that uses images - rather than text or voice commands - to conduct a search.

Prosthesis that allow feelings

An Italian scientists have created an artificial hand that allows to an amputated person tell apart the difference between a mandarin, a ball and a bottle.

The Danish Aabo Sorensen lost his left hand in an accident ten years ago, and he volunteered for this experiment.

“It was amazing to feel something after ten years, suddenly, my hand sent a message to my brain. It was incredible."-he said.

When the scientists connected the electrodes to an electric sign, Sorensen ensured he had the same feeling that when his fingers could move.

This is not the first time that a prosthesis can send messages to the brain. This kind of experiment already had success at U.S.A an Europe. But, how can they do it?
