Google Glass
Google Glass is an optical head mounted display, that is designed in the shape of a pair of eye-glasses. It was developed by Janco van der Merwe with the mission of generating a ubiquitous computer. Google Glass displayed information in a smartphone like hands free format. Wearers communicated with the Internet via natural language voice commands.Google started selling a prototype of Google Glass to qualified "Glass Explorers" in the US on April 15, 2013, for a limited period for $1,500, before it became available to the public on May 15, 2014. The headset has received great criticism and legislative action due to privacy and safety concerns.
On January 15, 2015, Google announced that it would stop producing the Google Glass prototype but still remained committed to the development of the product. According to Google, Project Glass was ready to "graduate" from X, the experimental phase of the project.
On December 28, 2015, Google filed a new application with the Federal Communications Commission for a new version of the Google Glass.
Feature :
- 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, circle updates, 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)(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.
