Really interesting augmented reality glasses concept by Nokia. Nokia is experimenting with new types of interactions involving near-to-eye displays, gaze direction tracking, 3D audio, 3D video, gesture and touch.  A number of different vendors are coming to the table with similar concepts, most of which involve augmenting interfaces over space. After the first wave of glasses has hit the market users can expect interfaces to become even more integrated. More information about this project can be found here.
