Google Glass is a brand of smart glasses—an optical head-mounted display designed in the shape of a pair of eyeglasses.
It was developed by X ( with the mission of producing a ubiquitous computer.
Google Glass displayed information in a smartphone-like, hands-free format.

The headset received a great deal of criticism amid concerns that its use could violate existing privacy laws.net via natural language voice commands

FEATURES:

  • T ouchpad: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, circle updates, etc.
  • Camera: Google Glass has the ability to take 5 Mp photos and record 720p HD video. Glass Enterprise Edition 2 has an improved 8MP 80° FOV camera.

  • Display: The Explorer version of Google Glass uses a liquid crystal on silicon (LCoS)(based on an LCoS chip from Himax), field-sequential color system, 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 sensor 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



The Explorer's LCoS display is illuminated using sequential color LEDs that pass through a polarization conversion system, a polarizing beam splitter, a half-silvered mirror, and an anastigmat, collimating reflector formed on the nose end of the optical assembly.
