Google has received three patents for a “wearable display device” which appear to be the foundation for its most talked about latest technology gadget – Project Glass augmented reality glasses. The new glasses could be used much the way a smart phone is by corresponding with friends, listening to music, and searching information. They can also be used as a navigator. Engineers behind Project Glass say that early tests show the glasses are best suited for taking and sharing photos. So far there is no information as to when the new gadget will hit the stores and for how much. Earlier reports said the smart galsses would be commericially available by the end of this year.
