For the display they use a vibrating optic fibre. At least according to their patents. The fibre spins vibrates in a spiral pattern and uses a modulated RGB light to build up an image (like a CRT).

The latency on this demo looks pretty bad though.

Having a vibrating optic fibre in front of your eyes does not sound like 'something that you won't be shy to wear in public and that it will maintain "normal relationships with people."'
