Google Glass would track the direction in which the wearer was looking with a tiny screen on the left lens that users will have to look up to see. It sports a different look from traditional glasses, covering only one eye instead of two.
Microsoft also envisages a system whereby eye-tracking is used to select areas of focus within the scene. Information shown could follow a preprogrammed script – Microsoft uses the example of an opera, where background detail about the various scenes and arias could be shown in order – or on an ad-hoc basis, according to contextual cues from the surrounding environment.
You can control the software by swiping a finger on that right earpiece in different directions. And Inside the right earpiece — that is, the horizontal support that goes over your ear — Google has packed memory, a processor, a camera, speaker and microphone, Bluetooth and Wi-Fi antennas, accelerometer, gyroscope, compass and a battery. All inside the earpiece.
A product like Glass will give Google a big opportunity to take an outsized chunk of local mobile advertising growth. Google can directly deliver location based ads to a person visually, instead of having to rely on a person using their mobile phones.
Now, Google emphasized that Google Glass is still at a very, very early stage. Lots of factors still haven’t been finalized, including what Glass will do, what the interface will look like, how it will work, and so on. Google doesn’t want to get the public excited about some feature that may not materialize in the final version. And at the moment, Google is planning to offer the prototypes to developers 2013 in anticipation of selling Glass to the public.
