What Is Google Glass Features?

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.[33] 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.[34] Glass Enterprise Edition 2 has an improved 8MP 80° FOV camera.[35]

Display: The Explorer version of Google Glass uses a liquid crystal on silicon (based on an LCoS chip from Himax), field-sequential color systemLED illuminated display.[36] 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.[37][38]
