Optical Tech now here we GO: Google Glass

Google Glass was developed by Google X, the facility within Google devoted to technological advancements such as driverless cars.
Google Glass is smaller and slimmer than previous head-mounted display designs.
The Google Glass prototype resembled standard eyeglasses with the lens replaced by a head-up display. In mid-2011, Google engineered a prototype that weighed 8 pounds (3,600 g); it is now lighter than the average pair of sunglasses.
In April 2013, the Explorer Edition was made available to Google I/O developers in the United States for $1,500.
Touchpad: A touchpad is located on the side of Google Glass, allowing users to control the device by swiping through a timeline-like interface displayed on the screen. Sliding backward shows current events, such as weather, and sliding forward shows past events, such as phone calls, photos, circupdat, etc. 
Camera: Google Glass has the ability to take photos and record 720p HD video. 
Display: The Explorer version of Google Glass uses a Liquid Crystal on Silicon (LCoS), field-sequential color, LED illuminated display. The display's LED illumination is first P-polarized and then shines through the in-coupling polarizing beam splitter (PBS) to the LCoS panel. The panel reflects the light and alters it to S-polarization at active pixel sites. The in-coupling PBS then reflects the S-polarized areas of light at 45° through the out-coupling beam splitter to a collimating reflector at the other end. Finally, the out-coupling beam splitter (which is a partially reflecting mirror, not a polarizing beam splitter) reflects the collimated light another 45° and into the wearer's eye
